Abstract
Fasciola spp. is a major livestock parasite, especially in cattle, water buffalo, sheep, and goats. Infection reduces animal productivity, e.g., meat, dairy, wool and might cause death. In Thailand, reports of Fasciola spp. infection in livestock, especially dairy and beef cattle, are sparse. Pakchong district in Nakhon Ratchasima province is one of Thailand's largest farming areas for dairy and beef cattle, but the prevalence of Fasciola spp. infection has never been reported in this district. The landscape of this area is mainly a hilltop plateau with many water sources suitable for the development of lymnaeid snails, the intermediate host of Fasciola spp., which are essential for the parasite life cycle. This study surveyed the copro- and seroprevalence of Fasciola spp. infection in dairy and beef cattle farmed in Pakchong district by microscope-based examination, PCR, and indirect ELISA. Associated risk factors and geographic information data were collected and analyzed. Paired stool and serum samples were collected from 102 dairy cattle and 99 beef cattle from April to November 2021. Sample analyses demonstrated a high prevalence of Fasciola spp. infection, especially in beef cattle. The overall copro-prevalence was 5.97%, with 0.99% in dairy cattle and 11.11% in beef cattle. The overall seroprevalence was 23.88%, with 2.94% in dairy cattle and 45.45% in beef cattle. Moreover, the data indicated that infection status was not correlated with animal sex and age whereas consumption of natural grasses, water resources, housing floor, and farming system were significant risk factors. Data analysis by a geographic information system (GIS) demonstrated that an associated risk could be farmed in lowering areas, especially in Chan Thuck, Nong Sa Rai, and Khlong Muang subdistricts. In conclusion, this study reports the prevalence of Fasciola spp. infection in cattle in a major farming area of Thailand which could be beneficial for designing parasite control policies in this region as well as adapting this knowledge to other Fasciola spp. endemic areas.

Abstract
A high incidence of cholangiocarcinoma (bile duct cancer) has been observed in Thailand. This usually rare cancer has been associated with infection with the human liver fluke, Opisthorchis viverrini. Secretions of the parasite that interact with the host are thought to be a major component of its pathogenicity and proteolysis is a key biological activity of the secreted molecules. In this study, we present a molecular analysis of cysteine proteinase inhibitors (cystatins) of Opisthorchis viverrini. Six cDNA coding sequences of Opisthorchis viverrini cystatins, OvCys1-6, were cloned from the adult stage of the parasite using RT-PCR. Based on their sequences, OvCys1 and OvCys2 are classified as type 1 cystatins, while OvCys3-6 are classified as type 2 cystatins, with each containing a signal peptide and only one C-terminal disulfide bond. Their C-terminal region sequences are diverse compared with other cystatin members. Cystatins OvCys1, 3 and 4 were found in crude worm extracts and excretory-secretory (ES) products from the adult parasite using Western blot detection, while the other isoforms were not. Thus, OvCys1, 3 and 4 were selected for inhibition analysis and immune reactivity with Opisthorchis viverrini-infected hamster sera. OvCys1, 3, and 4 inhibited mammalian cathepsin L more effectively than cathepsin B. The pH range for their full activity was very wide (pH 3-9) and they were heat stable for at least 3 h. Unlike Fasciola gigantica cystatins, they showed no immune reactivity with infected hamster sera based on indirect ELISA. Our findings suggest that Opisthorchis viverrini cystatins are not major antigenic components in the ES product of this parasite and that other effects of Opisthorchis viverrini cystatins should be investigated.

Abstract
BACKGROUND Helminth infection is a global health issue that not only causes acute helminthiasis but long-term infection may lead to complicated symptoms as well as severe complications. The World Health Organization cooperated with the Ministry of Public Health in many countries, particularly where high prevalence, spending a lot of resources for limiting the infection. In Thailand, the incidence of parasitic helminth infections was continuously declined in the last few decades according to several campaigns for parasitic elimination. However, the rural community in the northeast of Thailand where the highest prevalence of the country still needs to be monitored. This present study aims to report the current prevalence of parasitic helminth infections in Nakhon Ratchasima and Chaiyaphum provinces where sharing a huge area of the northeastern region of Thailand but only a few studies have been published. METHODS The stool specimens were collected from 11,196 volunteers and processed by modified Kato-Katz thick smear, PBS-ethyl acetate concentration techniques, and PCR. The epidemiological data were collected, analyzed, and used for generating of parasitic hotspots. RESULTS The results indicated that O. viverrini remains the major parasite in this area with a total prevalence of 5.05% followed by Taenia spp., Hookworms, T. trichiura, and Echinostoma spp., respectively. Mueang district of Chaiyaphum province has the highest prevalence especially O. viverrini with a prevalence of 7.15% that higher than the latest national surveillance. Interestingly, the prevalence of O. viverrini was hugely reported (more than 10%) in five subdistricts. The geographic localization of O. viverrini infections revealed that a lot of water reservoirs such as the lakes or branches of the river in the two-most prevalent subdistricts. Our finding indicated that gender and age were insignificantly different. CONCLUSION This finding suggested that the parasitic helminth infection in the rural areas of northeast of Thailand remains high and the housing location is a major contributing factor for the parasitic infection.

Abstract
A rumen fluke Fischoederius elongatus is assigned to the type species of genus Fischoederius, family Gastrothylacidae. However, the mitochondrial sequences recently published are thought to be of inconsistent species, suggesting that several morphologically similar but genetically distinct species might be classified as Fischoederius elongatus. Thus, mentions of F. elongatus from South, Southeast, and East Asia might unintentionally refer to different species. The present work describes morphology and a full mitochondrial genome sequence of one of these species. The fluke specimens were collected from 2 infected cattle in Thailand. An interesting finding was the presence of a second tRNA-Asp gene next to a partial ND1 gene. It is suggested that these duplicated sequences are the remnants of non-reciprocal recombination events caused by inverted repeats located between ND2 and ND1 mitochondrial genes.

Abstract
Rumen flukes in the genus Fischoederius are neglected foodborne parasites of cattle in Asia. Fischoederius elongatus, first described in 1883 from a sample collected in Indonesia is the type-species of the genus and is found from South to East Asia. In this study Fischoederius spp were collected from cattle in Thailand. The flukes resembled F. elongatus and images of 48 specimens were taken and their DNA was isolated. The mtDNA sequence of the cytochrome c oxidase subunit I (COX1) gene was amplified by PCR and used for restriction analysis with MseI. Nine restriction patterns (A-I) were observed and the COX1 mtDNA sequence for each pattern was determined. Phylogenetic analysis clustered the nine COX1 sequences into five groups with 4.6-9.6 % sequence differences between the groups. This is beyond intragenic variation observed for the COX1 gene in other organisms and suggested that the analyzed specimens represented several species. A comparative transcriptome analysis of specimens with COX1 MseI patterns A, C, E supported this finding. The observed median base differences, both absolute and relative, in the protein coding sequences of 999 orthologs were similar to those between distinct fruit fly species. It is proposed that the genus Fischoederius contains undescribed species that follow the classic description of F. elongatus.

Abstract
The DM9 domain is a protein unit of 60–75 amino acids that has been first detected in the fruit fly Drosophila as a repeated motif of unknown function. Recent research on proteins carrying DM9 domains in the mosquito Anopheles gambiae and the oyster Crassostrea gigas indicated an association with the uptake of microbial organisms. Likewise, in the trematode Fasciola gigantica DM9-1 showed intracellular relocalization following microbial, heat and drug stress. In the present research, we show that FgDM9-1 is a lectin with a novel mannose-binding site that has been recently described for the protein CGL1 of Crassostrea gigas. This property allowed FgDM9-1 to agglutinate gram-positive and -negative bacteria with appropriate cell surface glycosylation patterns. Furthermore, FgDM9-1 caused hemagglutination across all ABO blood group phenotypes. It is speculated that the parenchymal located FgDM9-1 has a role in cellular processes that involve the transport of mannose-carrying molecules in the parenchymal cells of the parasite.

Abstract
Opisthorchis viverrini infection causes various complications in patients, ranging from asymptomatic to severe chronic disease including cholangiocarcinoma (CCA). O. viverrini is endemic in Southeast Asia and acting as a risk for CCA. Early diagnosis of O. viverrini infection can reduce the number of CCA cases. The routine diagnosis for opisthorchiasis is direct wet smear, sometimes coupled with concentration techniques, which has limitations when investigating light infection or if done by laboratorians with lack of experiences. PCR-based methods have been established for the detection of O. viverrini egg DNA from stool samples, but have never fully succeeded for light infections when compared to wet smear concentration techniques. This study aims to improve the PCR-based method for detection of O. viverrini eggs in stool samples by targeting the genes ITS-2, cox1, and cyb. The results reveal higher sensitivity than conventional concentration techniques, with all newly designed primers. ITS-2 has an overall sensitivity of 76.9% with 66.7% in the samples with < 50 EPG, while cox1 has shown 96.2% overall sensitivity and 94.1% in the same EPG intervals. Interestingly, the new pointing target, cyb, has shown 100% sensitivity in all egg intervals in this study, particularly for light infections (EPG less than 100). No cross-reactivity was found in Taenia spp., Trichuris trichiura, Ascaris lumbricoides, Capillaria philippinensis, and hookworm. The procedure is convenient, with shorter steps compared to previous reports, and it appears appropriate for use in the diagnosis of light infection with O. viverrini. These three genes are good candidates for use in PCR-based detection of the parasite eggs. Further testing with a larger cluster of samples is however necessary.

Abstract
Tegumental and excretory-secretory proteins are reported as diagnostic antigens for human opisthorchiasis. Rhophilin associated tail protein1-like (OvROPN1L) protein of Opisthorchis viverrini sperm tail showed potential as a diagnostic antigen. The OvROPN1L recombinant fragments were assayed for diagnostic antigenicity for human opisthorchiasis using indirect ELISA. The strongest antigenic region was a N-terminus peptide of M1 - P56. One synthetic peptide (P1, L3-Q13) of this region showed the highest antigenicity to opisthorchiasis. Sera from other parasitic infections including Strongyloides stercoralis, hookworm, Taenia spp, minute intestinal flukes, Paragonimus spp showed lower reactivity to P1. Peptide P1 is located in the disordered N-terminus of ROPN1L supporting its suitability as linear epitope. In the Platyhelminthes the N-terminal sequence of ROPN1L is diverging with taxonomic distance further suggesting that peptide P1 has potential as diagnostic tool in the genus Opisthorchis/Clonorchis. It should be further evaluated in combination with peptides derived from other O. viverrini antigens to increase its diagnostic power.

Abstract
Fascioliasis, caused by Fasciola hepatica and Fasciola gigantica infection, is a major food-borne trematodiasis in many places of the world, with the central region of Vietnam being reported as a highly endemic area. Stool examination for Fasciola eggs is not a sensitive method, and immunodiagnostic methods are preferable. We investigated various enzyme-linked immunosorbent assays (ELISAs) to evaluate their efficacy for fascioliasis diagnosis. Test sera used are primarily screened using an ELISA kit produced in Vietnam (VN kit; Viet Sinh Chemical Producing & Trading Co. Ltd., Ho Chi Minh City, Vietnam): Seropositive individuals having symptoms compatible with fascioliasis were regarded as clinically diagnosed fascioliasis cases. A commercial Fasciola IgG ELISA kit from Diagnostic Automation/Cortez Diagnostics, Inc. (USA kit; Woodland Hills, CA), which has been commonly used in Vietnam, was assessed and compared with in-house ELISA systems, including a cystatin-capture (CC) ELISA using crude worm extract (CWE) and an indirect ELISA using a synthetic peptide Ac-TPTCHWECQVGYNKTYDEE-NHMe designed from the F. gigantica cathepsin B (FgCB5) molecule. The USA kit was suitable for routine diagnosis after recalibration of the manufacturer's suggested cutoff point. Cystatin-capture ELISA with CWE provided good sensitivity and specificity with perfect agreement to the results of the USA kit. In dot-blot ELISA, recombinant FgCB5 reacted more strongly with human antisera than did other F. gigantica antigens tested. Enzyme-linked immunosorbent assay using the synthetic peptide fragment of the FgCB5 exhibited nearly 80% sensitivity and specificity, but the test results showed low agreement with CC-ELISA or the USA kit. In conclusion, the commercially available Fasciola IgG ELISA kit from the United States and the in-house CC ELISA using CWE are suitable for practical diagnosis for fascioliasis.

Abstract
The multifunctional calreticulin (CALR) was identified as a major calcium-binding protein of the endoplasmic reticulum before being recognized as a chaperone in the same place. Only later were activities of calreticulin outside the endoplasmic reticulum described that for example affect cell proliferation and the innate immune system. In the present work we have investigated those extracellular activities of CALR from the cancerogenic human liver fluke Opisthorchis viverrini (OvCALR), as they might be important in host/parasite interaction. We first demonstrate that OvCALR is released from the parasite and stimulates a specific humoral immune response. Recombinant OvCALR is then shown to suppress proliferation of primary endothelial cells, their motility and sprouting activities. The potential of OvCALR to interfere with the complement system is established, firstly by demonstrating its direct binding to C1q and, secondly by suppression of hemolysis of sensitized red blood cells. These findings suggest that OvCALR is an important parasite antigen that could modulate diverse host functions and support parasite survival.

Abstract
Four isoforms of calcium binding proteins containing 2 EF hand motifs and a dynein light chain-like domain in the human liver fluke Opisthorchis viverrini, namely OvCaBP1, 2, 3, and 4, were characterized. They had molecular weights of 22.7, 21.6, 23.7, and 22.5 kDa, respectively and showed 37.2–42.1% sequence identity to CaBP22.8 of O. viverrini. All were detected in 2- and 4-week-old immature and mature parasites. Additionally, OvCaBP4 was found in newly excysted juveniles. Polyclonal antibodies against each isoform were generated to detect the native proteins in parasite extracts by Western blot analysis. All OvCaBPs were detected in soluble and insoluble crude worm extracts and in the excretory-secretory product, at approximate sizes of 21–23 kDa. The ion-binding properties of the proteins were analyzed by mobility shift assays with the divalent cations Ca2+, Mg2+, Zn2+, and Cu2+. All OvCaBPs showed mobility shifts with Ca2+ and Zn2+. OvCaBP1 showed also positive results with Mg2+ and Cu2+. As tegumental proteins, OvCaBP1, 2, and 3 are interesting drug targets for the treatment of opisthorchiasis.

Abstract
Calreticulin (CALR), a multifunctional protein thoroughly researched in mammals, comprises N-, P-, and C-domain and has roles in calcium homeostasis, chaperoning, clearance of apoptotic cells, cell adhesion, and also angiogenesis. In this study, the spatial and temporal expression patterns of the Opisthorchis viverrini CALR gene were analyzed, and calcium-binding and chaperoning properties of recombinant O. viverrini CALR (OvCALR) investigated. OvCALR mRNA was detected from the newly excysted juvenile to the mature parasite by RT-PCR while specific antibodies showed a wide distribution of the protein. OvCALR was localized in tegumental cell bodies, testes, ovary, eggs, Mehlis’ gland, prostate gland, and vitelline cells of the mature parasite. Recombinant OvCALR showed an in vitro suppressive effect on the thermal aggregation of citrate synthase. The recombinant OvCALR C-domain showed a mobility shift in native gel electrophoresis in the presence of calcium. The results imply that OvCALR has comparable function to the mammalian homolog as a calcium-binding molecular chaperone. Inferred from the observed strong immunostaining of the reproductive tissues, OvCALR should be important for reproduction and might be an interesting target to disrupt parasite fecundity. Transacetylase activity of OvCALR as reported for calreticulin of Haemonchus contortus could not be observed.

Abstract
Opisthorchis viverrini is the causative agent of human opisthorchiasis in Thailand and long lasting infection with the parasite has been correlated with the development of cholangiocarcinoma. In this work we have molecularly characterized the first member of a protein family carrying two DM9 repeats in this parasite (OvDM9-1). InterPro and other protein family databases describe the DM9 repeat as a protein domain of unknown function that has been first noted in Drosophila melanogaster. Two paralogous proteins have been partially characterized in the genus Fasciola, Fasciola hepatica TP16.5, a novel tegumental antigen in human fascioliasis and, recently F. gigantica DM9-1, a parenchymal protein with structural similarity to nematode cytoplasmic motility protein (MFP2). In this study, we show further evidence that this family of trematode proteins is related to MFP2 in sequence and structure. Soluble recombinant OvDM9-1 was used for structural analyses and for production of specific antisera. The native protein was detected in soluble and insoluble crude worm extracts and in seemingly various oligomeric forms in the latter. The potential for oligomerization was supported by cross-linking experiments of recombinant OvDM9-1. Structure prediction suggested a β-rich secondary structure of the protein and this was supported by a circular dichroism analysis. Molecular modeling in Phyre2 identified both MFP2 domains as distant homologs of OvDM9-1. The protein was located in tegumental type tissue and the cecal epithelium in the mature parasite. Recombinant OvDM9-1 was used as target in indirect ELISA but sera from infected hamsters showed only marginal reactivity towards it. It is proposed that OvDM9-1 and other members of this protein family have a role in cellular transport through functions on the cytoskeleton.

Abstract
Cysteine proteases of the liver fluke Fasciola have been described as essential molecules in the infection process of the mammalian host. Destinct cathepsin Bs, which are already expressed in the metacercarial stage and released by the newly excysted juvenile are major actors in this process. Following infection their expression is stopped and the proteins will not be detectable any longer after the first month of development. On the contrary, the novel cathepsin B5 of Fasciola gigantica (FgCB5) described in this work was also found expressed in later juvenile stages and the mature worm. Like all previously described Fasciola family members it was located in the cecal epithelium of the parasite. Western blot analysis of adult antigen preparations detected procathepsin B5 in crude worm extract and in small amounts in the ES product. In support of these data, the sera of infected rabbits and mice were reactive with recombinant FgCB5 in Western blot and ELISA. Biochemical analysis of yeast-expressed FgCB5 revealed that it has properties of a lysosomal hydrolase optimized for activity at acid pH and that it is able to efficiently digest a broad spectrum of host proteins. Unlike previously characterized Fasciola family members FgCB5 carries a histidine doublet in the occluding loop equivalent to residues His110 and His111 of human mature cathepsin B and consequently showed substantial carboxydipeptidyl activity which depends on these two residues.

Abstract
Determining of the success of a parasite's infectiveness in its snail host clearly depends on environmental conditions. Temperature, one of the most influential factors impinging on metabolism of cold-blooded animals, is believed to be an important factor in parasitic infection in snails. In order to elucidate the influence of temperature, sex and size of snails on infectivity of Opisthorchis viverrini to its first intermediate host, Bithynia siamensis goniomphalos, 960 snails were divided into 2 groups by sex. Each group was subdivided by their size into small and medium sub-groups. Each snail was fed with embryonated uterine-eggs of O. viverrini at different temperatures (16-37°C, 3°C intervals). Dissections were carried out 1, 7, 14, 28 and 56 days thereafter and detection of O. viverrini infection was undertaken by PCR using specific primers. Infection was strongly temperature-dependent, as temperature increases of 1°C resulted in increased odds of infection 5.4% (P<0.01). A temperature of 34°C gave the highest rate of infection of 44.14%. We also found that the odds of infection in small sized snails was 39.8% higher relative to medium sized snails (P<0.05). Relative to day 1, the decrease in the odds of infection was detected when the day post infection was longer (P<0.01). Proportion of infection in female was not different to male significantly.

Abstract
Concurrent deficiency of rhophilin associated tail protein (ROPN1) and ROPN1-like (ROPN1L) in mice causes structural abnormalities and immotility of sperm and thereby infertility. In the present research, ROPN1L of the human liver fluke Opisthorchis viverrini was molecularly characterized and showed unexpected potential as a diagnostic tool. ROPN1L transcripts were detected in 2-week-old juveniles by RT-PCR. Immunohistochemical analysis of the adult worm localized the protein in testis lobes, seminal vesicle and receptacle and immunoelectron microscopic analysis revealed its location on the tail of spermatozoa. Interestingly, sera of experimentally infected hamsters and sera of individuals suffering from opisthorchiasis showed reactivity to recombinant OvROPN1L (rOvROPN1L). The protein shows modest conservation to the human homolog at 47.2% sequence identity and a mouse anti-rOvROPN1L antiserum was not reactive with sperm protein extracts from hamsters, mice and rats. Unsurprisingly, conservation is higher in trematodes, e.g. 78.4% and 71.2% identity to Fasciola gigantica and Schistosoma haematobium, respectively and evaluation of diagnostic specificity is required using sera of individuals suffering from different trematodiases in Thailand.

Abstract
UNLABELLED The snail Bithynia siamensis goniomphalos acts as the first intermediate host for the human liver fluke Opisthorchis viverrini, the major cause of cholangiocarcinoma (CCA) in Northeast Thailand. The undisputed link between CCA and O. viverrini infection has precipitated efforts to understand the molecular basis of host-parasite interactions with a view to ultimately developing new control strategies to combat this carcinogenic infection. To date most effort has focused on the interactions between the parasite and its human host, and little is known about the molecular relationships between the liver fluke and its snail intermediate host. In the present study we analyse the protein expression changes in different tissues of B. siamensis goniomphalos induced by infection with larval O. viverrini using iTRAQ labelling technology. We show that O. viverrini infection downregulates the expression of oxidoreductases and catalytic enzymes, while stress-related and motor proteins are upregulated. The present work could serve as a basis for future studies on the proteins implicated in the susceptibility/resistance of B. siamensis goniomphalos to O. viverrini, as well as studies on other pulmonate snail intermediate hosts of various parasitic flukes that infect humans. BIOLOGICAL SIGNIFICANCE Despite the importance and high prevalence of opisthorchiasis in some regions of Southeast Asia and the direct relationship between infection by Opisthorchis viverrini and the incidence of cholangiocarcinoma, little is known of the modifications induced by this parasite in its snail intermediate hosts. This time-course study provides the first in-depth quantitative proteomic analysis of experimentally infected Bithynia siamensis goniomphalos. We show how motor and stress-related proteins are upregulated in infected snails, while O. viverrini infection downregulates the expression of oxidoreductases and catalytic enzymes. This work serves as a basis for the development of new strategies, focused on the invertebrate intermediate hosts, to control parasite transmission.

Abstract
PURPOSE Legionella is a common cause of community-acquired pneumonia (CAP) and is second only to Pneumococcal pneumonia as a cause of severe CAP that requires treatment in an intensive care unit. We report a case series of patients with severe Legionella pneumonia who developed the acute respiratory distress syndrome (ARDS), failed to improve with mechanical ventilation alone and required extracorporeal life support (ECLS). METHODS We performed a retrospective study of all patients treated with ECLS at our institution for severe ARDS as a result of Legionella pneumonia from 1994 to 2006. RESULTS A total of twelve patients with a diagnosis of Legionella pneumonia were treated with veno-venous (VV) ECLS over this time period. Nine of these twelve (75%) were successfully treated and weaned off ECLS and 8 patients (67%) survived to hospital discharge. Two (13%) died of multisystem organ failure, one patient (8%) died from global hypoxic encephalopathy and one (8%) was weaned from ECLS, but ultimately died of liver failure. Renal failure requiring some form of continuous dialysis occurred in seven patients (58%) and the survival for this sub-set of patients was 43%. CONCLUSIONS Extracorporeal life support for severe ARDS associated with Legionella pneumonia is an effective treatment option when mechanical ventilation fails, especially when introduced early in the course.

Abstract
BACKGROUND We developed an allele-specific polymerase chain reaction (AS-PCR) technique for Kidd blood group genotyping. METHODS Altogether, 340 blood samples from Thai blood donors at the National Blood Centre, Thai Red Cross Society, were tested with anti-Jk(a) and anti-Jk(b) using the gel technique and the direct urea lysis test was used for screening Jk(a-b-) phenotype. For AS-PCR technique, different types of primers were used for JK*01 and JK*02 allele detections in known DNA controls. RESULTS Regarding JK*02 allele detection, the pseudopositve amplification products were found when using correctly matched forward primer and a single mismatch forward primer. Interestingly, one type of two mismatch pairing at the 3' end of the forward primer can be used together with the newly designed reverse primer for Kidd blood group genotyping. It was found that the typing results in all samples obtained by serological techniques and newly developed AS-PCR technique were in agreement and this PCR technique also gave 100% concordance of results in 30 samples randomly tested twice and demonstrated reproducible results. CONCLUSION This study shows that the in-house AS-PCR is simple, cost-effective, and convenient for Kidd blood group genotyping in routine laboratories, especially, in resolving serologic investigations.

Abstract
Transcriptome data supports the notion of a Platyhelminthes-specific protein family that is characterized by combination of two N-terminal EF-hands and a C-terminal dynein light chain-like domain. Family members in schistosomes induce an IgE response that has been connected with resistance to reinfection in schistosomiasis and is considered as a marker of protection. In the present study, we have compared three homologs of the liver fluke Fasciola gigantica for their immunological properties in mouse. Antisera raised against the recombinant proteins detected the native proteins in tegumental type tissues and epithelial linings of excretory system and intestinal tract. The recombinant EF-hand domains induced strong IgG and IgE responses in immunised mice while only weak to moderate responses were observed against the complete recombinant proteins and their DLC-like domains. Parasite crude worm and tegumental extract antisera reacted predominantly with one isoform and its EF-hand domain. Sera of F. gigantica infected mice did not react with the recombinant proteins. The RNA products of the three genes were detected from the metacercarial up to the adult stage. These observations indicate that the investigated EF-hand proteins are not at the frontier of humoral host/parasite interaction in acute fascioliasis gigantica in mouse but are acting as intracellular proteins in tissues that interface with the parasite's environment or tubular tracts.

Abstract
The aim of the present study was to find evidence for a homologous protein of the mammalian cytochrome P450 family member CYP2B1/B2 in Plasmodium falciparum at the nucleic acid level. Prior research had demonstrated enzyme activity in the parasite comparable to mammalian CYP1A, 2A, 2B and 2E enzymes and presence of CYP enzymes by spectrophotometric and electrophoretic analyses. In recent years, the transcriptome/proteome data of P. falciparum and other Plasmodium spp. have been published and we performed an in silico analysis to identify putative cytochrome P450 family members in the parasite. This analysis failed to identify homologs to CYP1A, 2A, 2B and 2E enzymes in Plasmodium. A prior study had also claimed the presence of a conserved CYP2B1/B2 gene in the parasite by using Northern analysis with a rat CYP2B1/B2 probe. We have repeated this analysis by cloning a rat CYP2B1/B2 cDNA and using it as a hybridization probe against total RNA extracted from P. falciparum K1 and 3D7 clones but did not obtain positive results. This is consistent with the transcriptome/proteome sequence data and suggests that the genus Plasmodium contains either only highly diverged CYP proteins which are not easily identified by their primary sequence or that they have been functionally replaced by other enzymes. It is suggested that further studies are performed that allow isolation and identification of such proteins through their functional activities.

Abstract
Cathepsin proteases are promising vaccine or drug targets for prophylaxis or therapy against Fasciola parasites which express cathepsin L and B proteases during their development. These proteases are believed to be involved in important functions for the parasite, including excystment, migration, feeding and host immune evasion. Several cathepsin L transcripts, including FhCatL5, have been isolated from adult Fasciola, while certain cathepsin L proteases, including FgCatL1G, have only been identified in the juvenile forms of the parasite. In this study, Fasciola hepatica cathepsin FhCatL5 and F. gigantica FgCatL1G were expressed in yeast and their biochemical properties characterised and compared. The pH profiles of activity and stability of the two recombinant cathepsins was shown to differ, differences that are likely to be functionally important and reflect the environments into which the cathepsins are expressed in vivo. Biochemical analysis indicates that FgCatL1G can cleave substrates with proline residues at P(2), a characteristic previously described for the adult cathepsin FhCatL2. FgCatL1G and FhCatL5 show differences in their host substrate digestion patterns, with different substrates cleaved at varying efficiencies. Functional analysis of a recombinant FhCatL5 L69W variant indicates that the residue at position 69 is important for the S(2) subsite architecture and can influence substrate specificity.

Abstract
Fascioliasis, caused by liver flukes of the genus Fasciola, is an important disease of ruminants. In order to identify a potential new drug target we have studied aquaporin (AQP) in Fasciola gigantica. AQPs facilitate the transport of water, glycerol and other small solutes across biological membranes. The structure, function, and pathology of AQPs have been extensively studied in mammals but data for AQPs from trematodes is still limited. In the present study, we have functionally characterized two closely related AQP isoforms, FgAQP-1 and FgAQP-2, from the trematode F. gigantica. Immunohistochemical analysis located the FgAQPs in the tegumental cells, their processes and the tegument itself. In addition, they were present in the epithelial linings of testes and ovary. Expression in Xenopus oocytes of these FgAQPs increased osmotic water permeability 3-4-fold but failed to increase glycerol and urea permeability. AQPs have two highly conserved NPA motifs that are important for the function of the channel pore. In FgAQP-1 and FgAQP-2 the first NPA motif is changed to TAA. Substitution of Thr with Asn in the TAA motif of FgAQP-1 increased its water permeability twofold but did not affect urea and glycerol impermeability while the substitution at the pore mouth of Cys204 by Tyr caused loss of water permeability. In addition, the FgAQPs did not increase methylamine and ammonia permeability after expression in yeast. In comparison to rat AQP-1 the described FgAQPs showed low water permeability and further in vivo analyses are necessary to determine their contribution to osmoregulation in Fasciola.

Abstract
Freshwater snails of the family Lymnaeidae are the intermediate hosts of the liver fluke Fasciola worldwide. While distinct species have been identified at the molecular level in other parts of the world such data have not been published for Thailand. In this study we collected Lymnaeidae from different localities across Thailand and analyzed their 16S rDNA sequences as a molecular signature for classification. In addition to the ubiquitous Radix rubiginosa, we have confirmed the presence of Austropeplea viridis and Radix swinhoei, for the latter of which the ribosomal rDNA sequences are reported for the first time, in North-Thailand. Based on the obtained 16S rDNA data three primer pairs were designed that allowed rapid identification of these snail species by PCR. To determine their infection status, PCR primers for F.gigantica cathepsin L were used in parallel with the snail 16S rDNA species-specific primers in multiplex PCR analyses. Western blot analysis of total snail protein with a monoclonal anti-F.gigantica cathepsin L antibody confirmed positive cathepsin L PCR results. The developed diagnostic PCR will be of use in risk assessment for transmission of fascioliasis in Thailand.

Abstract
The liver fluke Opisthorchis viverrini is the agent of human opisthorchiasis in Thailand with a high prevalence observed in the rural population of north and northeastern regions of the country. A focus of research has therefore been the development of diagnostic tools to indicate infection by this parasite. In the present study, a 28 kDa glutathione S-transferase of O. viverrini (OV28GST), which is found in the excretion/secretion product of the parasite, was evaluated for its application in diagnosis of human opisthorchiasis. Bacterially expressed and functionally active rOV28GST was used in immunoblots and indirect ELISA to detect anti-OV28GST antibody in sera of infected individuals. Crude whole worm extract, sera of uninfected individuals and a rabbit anti-rOV28GST antiserum were used as controls in the assays while positivity for parasite DNA by PCR and egg count in faeces were used as primary indicators of infection. The results showed weak or absent reactivity of the infected sera to immunoblotted rOV28GST and no significant difference in absorbance values when compared to uninfected sera in ELISA. In addition, a glutathione capture ELISA which was performed to test for circulating OV28GST in human and hamster sera showed negative results. In conclusion, OV28GST is not applicable as a diagnostic tool in established infections due to low specific antibody titre and abundance as circulating antigen.

Abstract
In the present study we describe type 1 cystatin, a cysteine protease inhibitor, as a major released antigen of the tropical liver fluke Fasciola gigantica (FgStefin-1). Immunohistochemical analysis showed that FgStefin-1 is abundant in (a) tissue of tegumental type, including oral and ventral sucker, pharynx, genital atrium, metraterm, cirrus and (b) the intestinal epithelium. Faint staining was observed in the epithelia of ovary and proximal uterus. Immunoblots showed the presence of FgStefin-1 in the parasite's excretion/secretion (ES) product and immunodepletion demonstrated that FgStefin-1 herein is partially complexed with cathepsin L. Furthermore, quantitation of FgStefin-1 in comparison to cathepsin L in ES product and crude worm extract of adults supports a major external function of FgStefin-1 with an estimated 50% being released in at least equimolar amounts to cathepsin L. Sera of an experimentally infected rabbit reacted with recombinant FgStefin-1 starting 8 weeks postinfection. Activity analyses of recombinant FgStefin-1 showed nanomolar inhibition constants for mammalian cathepsin B, L, and S cysteine proteases and released cysteine proteases of the parasite. The protein is active over a wide pH range and is heat stable. Our results suggest protective functions of FgStefin-1, regulating intracellular cysteine protease activity, and possibly protection against extracellular proteolytic damage to the parasite's intestinal and tegumental surface proteins. Considering inhibition kinetics and previously demonstrated immunomodulatory properties of cystatin in parasitic nematodes a comparable function of FgStefin-1 is suggested and is at present under investigation.

Abstract
A cDNA containing a 813 bp open reading frame encoding vitelline protein BI (FgVPBI) of Fasciola gigantica was cloned. FgVPBI has 96% sequence identity with VPBI of Fasciola hepatica and 84% identity with VPBII F. hepatica. It is far less similar to eggshell precursor proteins of other trematode species, for example, 29% identity with C. sinensis. Northern blot hybridization of total RNA from adult parasites demonstrated a FgVPBI transcript with a size of 1,000 nucleotides. FgVPBI mRNA is localized in the vitelline cells in both vitelline glands and intrauterine eggs. Recombinant FgVPBI was expressed as a 31.5 kDa protein in Escherichia coli and used for production of a polyclonal antiserum in rabbits. The FgVPBI antiserum detected immunoblotted rFgVPBI and native eggshell precursor protein at molecular weights of 31.5 kDa and 31 kDa, respectively. Immunolocalization showed strong staining in the cytoplasm of vitelline cells, in eggshell globules and the shells of eggs.

Abstract
Liver flukes produce cathepsin B and cathepsin L in their excretory-secretory material. These proteases are proposed to be key virulence factors for parasite infection, and are therefore targets for vaccination. Cathepsin B is predominately released in the juvenile stage of the life cycle, while different cathepsin L's are released throughout the cycle. Three proteases (cathepsin L5, cathepsin L1g and cathepsin B) were expressed in yeast from cDNA clones isolated from adult, metacercariae and newly excysted juvenile flukes respectively. Each was used singly or in combination to vaccinate rats that were subsequently challenged with Fasciola hepatica metercercariae. Each protein induced an immune response, and all groups vaccinated with recombinant protein yielded significantly fewer and smaller flukes than the control group. Maximal protection of 83% was seen in the group vaccinated with cathepsin B and cathepsin L5 in combination.

Abstract
In this study we describe the first cysteine proteinases of the MEROPS Clan CD family C13 in Fasciola gigantica. Family C13 contains asparaginyl endopeptidases and glycosylphosphatidylinositol-anchor transamidases and is also called the legumain family due to the discovery of the first asparaginyl endopeptidase in a legume. The cDNAs encoding two asparaginyl endopeptidases, FgLGMN-1 and FgLGMN-2, were cloned and used for the analysis of nucleic acid and protein properties. The deduced amino acid sequences showed 47.4% identity to each other and from 42.2 to 51.1% identity to homologs of other trematode species. The catalytic site residues histidine, cysteine and preceding hydrophobic residues, characteristic for the cysteine proteinase families C11, C13, C14, and C25, were found conserved. Northern and reverse transcription PCR analyses demonstrated that the transcriptional products are present in metacercariae, juveniles and adults. RNA in situ hybridization and immunohistochemistry revealed that RNA and protein products of the two genes are specifically expressed in the intestinal epithelium of juveniles and adults. Immune sera of mice infected with F. gigantica reacted with immunoblotted, bacterially expressed recombinant proteins starting 4 weeks after infection. Polyclonal antisera raised against the recombinant proteins detected 40 and 30 kDa antigens, respectively in crude worm protein extracts but not in the excretion-secretion products of adult parasites. Likewise, legumain-specific activity was found in crude worm protein extracts but not in excretion-secretion products. This study elucidates the molecular characteristics of these proteins in F. gigantica and demonstrates differences in the biology between Fasciola and Schistosoma which may prove useful for the development of vaccines against fasciolosis in domestic livestock.

Abstract
Fatty acid binding proteins (FABPs) are capable of binding hydrophobic ligands with high affinity; thereby facilitating the cellular uptake and intracellular trafficking of fatty acids. In this study, functional characteristics of a cytoplasmic FABP from the giant liver fluke Fasciola gigantica (FgFABP) were determined. Binding of a fluorescent fatty acid analogue 11-[[5-dimethy aminonaphtalene-1-sulphonyl] amino] undecanoic acid (DAUDA) to FgFABP resulted in changes in the emission spectrum. The optimal excitation wavelength and maximum emission of fluorescence for binding activities with DAUDA were 350 nm and 550 nm, respectively. The binding activity for DAUDA was determined from titration experiments and revealed a Kd value of 2.95+/-0.54 microM. Furthermore, we found that cross-linking profile of FgFABP with dithiobis-(succinimidylpropionate) (DSP) in the presence of DAUDA resulted in increased formation of higher-ordered oligomers compared to that in the absence of DAUDA. We also replaced five highly conserved positively charged residues (K9, K58, K91, R107 and K131) with alanine and studied their oligomerization and binding properties of the modified FgFABPs. The obtained data demonstrate that these residues do not appear to be involved in oligomerization. However, the K58A and R107A substitutions exhibited a reduction in binding affinities. K91A and R107A revealed an increase in maximal specific binding.

Abstract
Parenchymal cells in adult Fasciola gigantica can be classified into three types based on their ultrastructural features and different quantities of fatty acid binding protein (FABP) being stored. Parenchymal cell type 1 (Pc1) has pale cytoplasm consisting largely of a loose network of fine fibers, and it contains few mitochondria but numerous glycogen particles. This cell type may be specialized in the storage and metabolism of glycogen and glucose. Parenchymal cell type 2 (Pc2) has similar cytoplasmic features as Pc1 but contains more numerous mitochondria, and high concentration of FABP as reflected by high density of immunostaining and immunogold labeling using specific monoclonal antibody (MoAb) to FABP as probe. Pc2 may, thus, specialize in the storage and metabolism of fatty acids and other lipids. Parenchymal cell type 3 (Pc3) has dense cytoplasm containing large amount of rough endoplasmic reticulum, Golgi complex and mitochondria, which is typical of a secretory cell. Furthermore, Pc3 has very little glycogen particles and is not stained by MoAb against FABP. It could, thus, be concerned with the synthesis of fibers, which form the scaffold of the parenchyma.

Abstract
A cDNA encoding Fg14-3-3 protein 1 was cloned by immunoscreening of an adult-stage Fasciola gigantica cDNA library using a rabbit antiserum against tegumental antigens of the parasite. The protein has a deduced amino acid sequence of 252 residues and a calculated molecular weight of 28.7 kDa. It shows sequence identity values between 57.6 and 58.1% to the human 14-3-3 beta, zeta, theta, and eta proteins and is in a phylogenetic cluster with the 14-3-3 protein 1 of Schistosoma spp. Nucleic acid analyses indicate that the Fg14-3-3 protein 1 is encoded by a single copy gene and that this gene is expressed as a transcript of 1250 nucleotides. In adult and 4-week-old parasites the gene's transcriptional and translational products were localized in the gut epithelium, parenchyma, tegument cells, and in the reproductive organs. An antiserum against recombinant Fg14-3-3 protein 1 detected a slightly smaller 14-3-3 protein in the parasite's excretion/secretion material and showed cross-reactivity with 14-3-3 proteins in extracts of other trematodes and mouse. Antibodies against Fg14-3-3 protein were detected in the sera of rabbits as early as 2 weeks after infection with metacercariae of F. gigantica and the antibody titre increased continuously over a 10-week observation period.

Abstract
A cDNA encoding a novel eggshell protein (OvESP) with high-glycine (49.2%) and -tyrosine (27.8%) content was cloned from the human liver fluke Opisthorchis viverrini. In the adult parasite, the RNA products of the OvESP gene are limited to the vitelline follicles. They have a size of 800 nucleotides and are already present in 2-week-old juveniles. Immune sera of hamsters, experimentally infected, and humans, naturally infected with O. viverrini, detect bacterially expressed recombinant OvESP (rOvESP). A rabbit anti-rOvESP antiserum only reacts with the shells of intrauterine eggs in tissue sections of the parasite. Comparison of rOvESP with the parasite's excretion/secretion products as diagnostic tools for human opisthorchiasis shows a higher sensitivity (0.82-0.48) and specificity (0.97-0.91) of the recombinant protein in the ELISA technique. But the observed weak cross-reactivity of immune sera from mice infected with Schistosoma mansoni, Schistosoma mekongi, and Fasciola gigantica in Western blots of rOvESP indicates that the diagnostic quality of this protein might be compromised if infections by other trematodes are present.

Abstract
The SAP genes of Fasciola encode proteins belonging to the saposin-like protein family. The saposin signature, a compact domain of mainly alpha-helical character, contains six conserved cysteine residues and has been implicated in membrane-binding, pore formation, and subsequent cell lysis in several family members. Recombinant SAP-2 of F. hepatica has been shown to induce lysis of human erythrocytes and peripheral blood mononuclear cells. This suggests that the SAPs are involved in the nutrition of Fasciola as the released content of lysed host cells is available for further enzymatic processing and uptake by the parasite. In the present study a new SAP-3 cDNA was obtained in an immunoscreen of an adult stage F. gigantica cDNA library with an antiserum against the parasite's excretion/secretion antigens. SAP-1 and SAP-2 cDNAs were isolated from F. gigantica cDNA libraries using oligonucleotide primers specific to the SAP-1 and SAP-2 DNA sequences from F. hepatica. Transcripts of the three SAPs are present from the metacercarial to the adult stage and are located to the gut epithelium. In immatures SAP-1 RNA is the predominant product whereas in adults SAP-2 and -3 are the more abundant products. Polyclonal anti-SAP-1 and SAP-2 antisera confirmed the tissue-specificity and revealed the subcellular localization of SAPs in large granules concentrated in the apical part of the gut epithelial cells of the parasite. Interestingly, evolutionary conservation of the Fasciola SAP sequences among other trematodes is low at 20-30% sequence identity comparable to the Entamoeba amoebapore sequences.

Abstract
A full-length cDNA encoding the Fasciola gigantica calcium-binding protein 1 (FgCaBP1) was cloned from an adult stage cDNA expression library in an immunoscreen using rabbit immune serum against the parasite's excretion/secretion antigens. The deduced amino acid sequence showed 96.3% identity to Fh22CBP of Fasciola hepatica. During development in the mammalian host FgCaBP1 RNA was detected in metacercariae, juveniles and adults and was exclusively localized to the tegumental cell bodies. Immune serum of a rabbit infected with F. gigantica detected recombinant FgCaBP1 starting from the sixth week of infection. Immune sera of mice infected with Schistosoma mansoni and Schistosoma mekongi cross-reacted with recombinant FgCaBP1 in immunoblots. Recombinant FgCaBP1 showed calcium and magnesium-binding activity by a mobility shift during non-denaturing PAGE in the presence of Ca2+ or Mg2+, respectively. A polyclonal mouse anti-rFgCaBP1 antiserum detected the native protein as a major component of the parasite's tegumental antigens in immunoblots and as a strictly tegumental antigen in tissue cross-sections of adult and juvenile parasites. Comparative sequence analysis of homologs from Fasciola and Schistosoma present in the GenBank database revealed sequence signatures specific to these trematode proteins and thereby indicates their origin from a single ancestor. FgCaBP1 contains two adjacent, N-terminal located EF-hands and a C-terminal located domain similar to dynein light chain type 1. Independent structure predictions of the two domains suggest that they will fold according to the already determined structures of the EF-hand motif and the dynein light chain type 1 proteins.

Abstract
An adult stage Opisthorchis viverrini cDNA library was constructed and screened for abundant transcripts. One of the isolated cDNAs was found by sequence comparison to encode a glutathione S-transferase (GST) and was further analyzed for RNA expression, encoded protein function, tissue distribution and cross-reactivity of the encoded protein with other trematode protein counterparts. The cDNA has a size of 893 bp and encodes a GST of 213 amino acids length (OV28GST). The most closely-related GST of OV28GST among those published for trematodes is a 28 kDa GST of Clonorchis sinensis as shown by multiple sequence alignment and phylogenetic analysis. Northern analysis of total RNA with a gene-specific probe revealed a 900 nucleotide OV28GST transcriptional product in the adult parasite. Through RNA in situ hybridization OV28GST RNA was detected in the parenchymal cells of adult parasites. This result was confirmed by immunolocalization of OV28GST with an antiserum generated in a mouse against bacterially-produced recombinant OV28GST. Both, purified recombinant and purified native OV28GST were resolved as 28 kDa proteins by SDS-PAGE. Using the anti-recOV28GST antiserum, no or only weak cross-reactivity was observed in an immunoblot of crude worm extracts against the GSTs of Schistosoma mansoni, S. japonicum, S. mekongi, Eurytrema spp. and Fasciola gigantica. The enzyme activity of the purified recombinant OV28GST was verified by a standard 1-chloro-2, 4-dinitrobenzene (CDNB) based activity assay. The present results of our molecular analysis of OV28GST should be helpful in the ongoing development of diagnostic applications for opisthorchiasis viverrini.

Abstract
The transcriptional products of Fasciola gigantica genes encoding cathepsin B proteases were cloned from adult, newly excysted juvenile (NEJ), and metacercarial stages. The obtained cDNAs were named FG cat-B1, FG cat-B2, and FG cat-B3. The deduced amino acid sequences of the encoded proteases have identities ranging from 64 to 79%. Sequence comparison with homologous proteins showed that all functional important residues formerly described for cathepsin B are conserved. Southern analysis confirmed the presence of a family of related cathepsin B genes in the genome of F. gigantica. Northern analysis revealed a common transcript size of 1400 nucleotides with abundant cathepsin B transcripts detected in metacercarial and NEJ stages. Cathepsin B transcripts were located by RNA in situ hybridization in the caecal epithelial cells, in cells underlining the proximal part of the digestive tract, and in the tegumental cells underlining the surface tegument. Furthermore, transcripts were detected in the tissues of the reproductive system including cells of prostate, Mehlis, and vitelline glands, testis, and eggs. Stage-specific gene expression was investigated by RT-PCR using gene-specific primers and hybridization with a labeled cathepsin B probe. FG cat-B1 transcripts were detected in all stages, whereas FG cat-B2 and FG cat-B3 transcripts were expressed in metacercariae, NEJ, and juvenile parasites only. The switching off of the cat-B2 and cat-B3 genes during the maturation of the parasites implicates that these enzymes may be involved in digesting host tissues during penetration and migration to the liver, whereas cat-B1 present in all stages may perform general digestive function.

Abstract
A monoclonal antibody (MoAb) against a recombinant glutathione S-transferase (rGST) of F. gigantica was produced in BALB/c mice. Reactivity and specificity of this monoclonal antibody was assessed by ELISA and immunoblotting. Six stable clones, namely 3A3, 3B2, 3C6, 4A6, 4B1 and 4D6 were obtained, All these MoAb reacted with rGST and native GST at a molecular weight of 28 kDa and found to be IgG1, kappa-light chain isotypes. These MoAb cross-reacted with Schistosoma mansoni and Schistosoma japonicum antigens at molecular weights of 28 and 26 kDa, respectively, but no cross-reactions were detected with antigens of Eurytrema and Paramphistomum spp. The localization of GST in metacercaria, 7-week-old juvenile and adult F. gigantica was performed by immunofluorescence technique, using MoAb as well as polyclonal antibody (PoAb) to the native protein as probes. In general, all clones of MoAb gave similar results and the pattern was quite similar to staining by PoAb. The fluorescence was intense, which implied the presence of a high concentration of GST in the parenchymal tissue in all stages of the parasite. However, the parenchymal cells were not evenly stained which implied the existence of subpopulations of this cell type with regard to GST production and storage. In addition, in adult and juvenile stages a moderate fluorescence was present in the basal layer of the tegument, while light fluorescence was observed in the caecal epithelium, cells in the ovary, testis and vitelline gland of the adult. In the metacercaria stage, in addition to parenchymal tissue, the tegument and tegumental cells were stained relatively more intense with MoAb and PoAb than in other stages.

Abstract
A monoclonal antibody (MoAb) against the 28.5 kDa tegumental antigen of Fasciola gigantica was produced by the hybridoma technique using spleen cells from BALB/c mice immunized with the tegumental extract from adult F. gigantica. This MoAb was found to be of the isotype IgG(1), kappa-light chain, and shown by immunoblotting to specifically react with the 28.5 kDa antigen present in the tegument, excretion-secretion material of the adult, whole-body extracts of newly excysted juveniles, 5-week-old juvenile and adult parasites. It did not cross-react with antigens from other trematode parasites, including Schistosoma mansoni, Eurytrema pancreaticum and Paramphistomum spp. Immunolocalization of this antigen by indirect immunofluorescence indicated that it was present as a major component of the adult tegument, particularly in its outer rim, tegumental cells, and their processes. Furthermore, the epithelium linings of the oral sucker, buccal tube, pharynx, caecal bifurcation, both male and female genital canals, which were the continuation of the tegumental-type epithelium, were also positively stained with this MoAb. A similar pattern of immunolocalization, but with weaker staining intensity, was observed in newly excysted, 5- and 7-week-old juveniles. Thus this antigen is expressed in all developmental stages of the parasite, and it could be a strong candidate for immunodiagnosis and vaccine development.

Abstract
In Fasciola parasites fatty acid binding proteins (FABPs) are the carrier proteins that help in the uptake of fatty acids from the hosts' fluids. Attempts have been made to utilize both native and recombinant FABP (rFABP) for immunodiagnosis and vaccine development for fasciolosis. In this study, we have produced a number of monoclonal antibodies (MoAbs) against rFABP of Fasciola gigantica. These MoAbs were initially screened against rFABP by ELISA and then tested for their specificities by immunoblotting. Five stable clones were selected and characterized further: four of them were of the isotype IgG(1) while one clone was IgG(2a). All the MoAbs reacted with rFABP which has a molecular weight (MW) of 20 kD and with at least two isoforms of native proteins at MW 14.5 kD that were present in the tegumental antigen (TA) and crude worm extracts, and the excretion-secretion materials. Immunoperoxidase staining of frozen sections of adult parasites by using these MoAbs as primary antibodies indicated that FABP were present in high concentration in the parenchymal cells and reproductive tissues, in low concentration in the tegument and caecal epithelium. All MoAbs cross-reacted with a 14.5 kD antigen present in the whole body (WB) extract of Schistosoma mansoni, while no cross-reactivities were detected with antigens from Eurytrema pancreaticum and Paramphistomum spp.

Abstract
In this study cDNAs encoding cathepsin L-like proteins of Fasciola gigantica were cloned by the reverse transcription polymerase chain reaction method (RT-PCR) from total RNA of adult specimens. DNA sequence analyses revealed that six different cathepsin L cDNA fragments were isolated, which have DNA sequence identities of 87-99% towards the homologous genes from F. hepatica. Gene expression was studied at the RNA level by Northern and RNA in situ hybridizations. Northern analysis showed the cathepsin L genes to be strongly expressed in adult parasites as a group of 1050 nt sized RNAs. RNA in situ hybridization localized cathepsin L RNA to the cecal epithelial cells. Southern hybridization was used to determine the number of cathepsin L genes and indicated the presence of a family of closely related cathepsin L genes in the genome of F. gigantica.

Abstract
PURPOSE The aim of this study was to describe a single-center experience with pediatric extracorporeal life support (ECLS) and to determine variables predictive of outcome in pediatric patients, both before the institution of ECLS and while on support. METHODS From October 1985 to September 1998 the authors supported 128 children with severe acute hypoxemic respiratory failure(n = 121, Pao2/FIo2 ratio = 58+/-29) or acute hypercarbic respiratory failure (n = 7, Paco2 = 128+/-37), despite maximal conventional ventilation. Mode of access included venoarterial bypass (VA, n = 64), venovenous bypass (VV, n = 53), and VV to VA bypass (n = 11). The techniques used included lung rest, pulmonary physiotherapy, diuresis to dry weight using hemofiltration if needed, minimal anticoagulation, and optimal systemic oxygen delivery. RESULTS The median age was 1.4 years (range, 2 weeks to 17 years). The mean duration of ECLS was 288+/-240 hours (range, 4 to 1148 hours or 0.2 to 47.8 days). Lung compliance increased from 0.32+/-0.02 mL/cm H2O/kg to 0.59+/-0.03 mL/cm H2O/kg in survivors, but only increased from 0.34+/-0.02 mL/cm H2O/kg to 0.35+/-0.02 mL/cm H2O/kg in nonsurvivors (P<.002 comparing change between survivors and nonsurvivors). Mean body weight decreased from 9%+/-2% over dry weight to 4%+/-2% in survivors, whereas in nonsurvivors the mean body weight increased from 25%+/-5% over dry weight to 35%+/-7% (P<.001). Outcome results by diagnosis were pneumonia, 73%; acute respiratory distress syndrome, 67%; and airway support, 60%, with overall lung recovery occurring in 77%, and hospital survival in 71%. Multivariate logistic regression modelling of patients with hypoxemic respiratory failure found the only pre-ECLS variable significantly associated with outcome to be pH (P<.05). Variables during the course of ECLS significantly associated with decreased survival were the presence of creatinine greater than 3.0 (P<.01), the need for inotropes (P<.04), failure to return the patient to dry weight (P<.04), and lung compliance that did not improve significantly. (P<.01). CONCLUSIONS ECLS provides life support in severe respiratory failure in children, allowing time for injured lungs to recover. Pre-ECLS predictors, such as pH and variables during ECLS, such as presence of renal failure, improvement in compliance, return to dry weight, and the need for inotropes on ECLS, may be useful for predicting outcome.

Abstract
The ring gland function of Drosophila melanogaster is controlled by the CNS. To identify genes that are active in brain cells and are involved in the ring gland control, we analysed enhancer trap lines with respect to CNS- and/or ring gland-specific lacZ expression in third-instar larvae. From one of the enhancer trap lines, which shows specific lacZ expression in the CNS and prothoracic part of the ring gland, the mub gene was cloned. The gene is strongly expressed in the mushroom bodies throughout development. Nucleotide sequence analysis of cDNA clones revealed a high degree of similarity to vertebrate RNA binding KH domain proteins, suggesting a function of the MUB protein in binding and stabilizing of specific mRNAs in the mushroom bodies. Null mutants of the mub gene do not exhibit a visible mutant phenotype. We speculate, therefore, that the mub gene is involved in learning and memory processes.
