Abstract
Microsporidia is a diverse group of obligate, intracellular, and spore-forming parasites that infect a wide range of animals. Among them, Enterocytozoon bieneusi and Encephalitozoon spp. are the most frequently reported species in humans. Limited information is available about the presence and molecular diversity of microsporidian species in the endangered Iberian lynx (Lynx pardinus). Presence of Enterocytozoon bieneusi and Encephalitozoon spp. was investigated by molecular methods in wild and captive Iberian lynxes from Spain. Overall, E. bieneusi was detected in 3.2% (8/251) of the animals examined. None of the samples tested were positive for Encephalitozoon spp. Four known (D, EbfelA, PigEBITS7, and Type IV) and a novel (named as LynxSpEb1) E. bieneusi genotypes were identified. All the genotypes found belonged to the zoonotic Group 1 of E. bieneusi. This study provides the first genotyping data of E. bieneusi in Iberian lynx in Spain. Our result indicate that the Iberian lynx does not seem to play a relevant role in the epidemiology of Encephalitozoon spp., and that this endangered felid is likely acting as spillover host rather than a true reservoir of E. bieneusi. Additional studies should be conducted to assess the impact of this parasite in the health status of the endangered Iberian lynx.

Abstract
Cryptosporidium spp. and Giardia duodenalis are the main non-viral causes of diarrhoea in humans and domestic animals globally. Comparatively, much less information is currently available in free-ranging carnivore species in general and in the endangered Iberian lynx (Lynx pardinus) in particular. Cryptosporidium spp. and G. duodenalis were investigated with molecular (PCR and Sanger sequencing) methods in individual faecal DNA samples of free-ranging and captive Iberian lynxes from the main population nuclei in Spain. Overall, Cryptosporidium spp. and G. duodenalis were detected in 2.4% (6/251) and 27.9% (70/251) of the animals examined, respectively. Positive animals to at least one of them were detected in each of the analysed population nuclei. The analysis of partial ssu rRNA gene sequences revealed the presence of rodent-adapted C. alticolis (n = 1) and C. occultus (n = 1), leporid-adapted C. cuniculus (n = 2), and zoonotic C. parvum (n = 2) within Cryptosporidium, and zoonotic assemblages A (n = 5) and B (n = 3) within G. duodenalis. Subgenotyping analyses allowed for the identification of genotype VaA19 in C. cuniculus (gp60 locus) and sub-assemblages AI and BIII/BIV in G. duodenalis (gdh, bg, and tpi loci). This study represents the first molecular description of Cryptosporidium spp. and G. duodenalis in the Iberian lynx in Spain. The presence of rodent/leporid-adapted Cryptosporidium species in the surveyed animals suggests spurious infections associated to the Iberian lynx's diet. The Iberian lynx seems a suitable host for zoonotic genetic variants of Cryptosporidium (C. parvum) and G. duodenalis (assemblages A and B), although the potential risk of human transmission is regarded as limited due to light parasite burdens and suspected low excretion of infective (oo)cysts to the environment by infected animals. More research should be conducted to ascertain the true impact of these protozoan parasites in the health status of the endangered Iberian lynx.

Abstract
BACKGROUND Pet dogs and cats exert an unquestionable beneficial effect in the well-being of their owners, but can also act as a source of zoonotic infections if improperly cared. OBJECTIVES We investigated the occurrence, risk factors, genetic variability and zoonotic potential of intestinal parasites in dogs and cats attended in a clinical veterinary setting in Spain. METHODS Canine (n = 252) and feline (n = 35) faecal samples were collected during 2017-2019 and analysed by coproparasitological methods. A rapid lateral immunochromatographic test (ICT) was used for detecting Giardia duodenalis and Cryptosporidium sp. Samples positive at microscopy examination and/or ICT were reassessed by molecular methods. RESULTS Overall, 48.8% (123/252) of dogs and 48.6% (17/35) of cats were infected by enteric parasites. In dogs, G. duodenalis was the most prevalent species (40.9%), followed by Cystoisospora sp. (7.1%), and Toxocara canis (5.2%). In cats, Joyeuxiella sp. and Toxocara cati were the dominant species (20.0% each), followed by G. duodenalis (14.3%), D. caninum (5.7%) and Cystoisospora felis and Toxascaris leonina (2.9% each). Pups and kittens were more likely to harbour intestinal parasites and develop clinical signs. Sequence analyses of dog isolates revealed the presence of assemblages A (n = 1), C (n = 4), D (n = 4) and C+D (n = 1) within G. duodenalis; C. parvum (n = 1) and C. canis (n = 4) within Cryptosporidium and PtEb IX (n = 1) in Enterocytozoon bieneusi. A novel C. canis subtype family, named XXi, is reported. CONCLUSIONS Our results highlight that (i) well-cared dogs carry zoonotic enteric protozoan parasites of public health relevance, (ii) proper hygiene practices and routine veterinary treatment are essential to prevent zoonotic infections, (iii) vulnerable populations should avoid contact with pups/kittens with diarrhoea and (iv) infected dogs might be major contributors to the environmental contamination with soil-transmitted helminths (STHs) eggs.

Abstract
INTRODUCTION AND OBJECTIVE The management of patients with metastatic hormone-sensitive prostate cancer (mHSPC) has changed in recent years due to the approval of new drugs. The aim of this study was to evaluate the prevalence, incidence, and treatment patterns in mHSPC in Spain. PATIENTS AND METHODS Multicenter, observational, longitudinal, retrospective study in routine clinical practice of patients diagnosed with mHSPC treated in Spanish hospitals between 2015 and 2019 (ECHOS study). Electronic medical records were extracted from BIG-PAC database, which contains geographically representative Spanish centers. RESULTS Data from 379 men with mHSPC were included. The prevalence of mHSPC ranged between 12.2-14.6% per year, representing from 671 to 824 annual cases with an increasing trend. The mean incidence along the 4-year period was 2.5%, with annual incidence ranging 2.2-3.0%. New annual cases of de novo and recurrent disease ranged between 7-11 and 77-104, respectively, with no trend being observed. These patients were mostly recurrent (91%) with high-volume disease (68.6%). The most common first-line therapy was ADT combined with docetaxel (53%), followed by ADT alone (23.8%), combination of ADT and abiraterone (11.2%), and radiotherapy (8.6%). In the last 12 months before diagnosis of metastasis, most men had been submitted to radical prostatectomy (84.9%). The remaining patients had received radiotherapy (12%) or no treatment at all (3.8%). CONCLUSIONS The ECHOS study provides epidemiologic data and current patterns of treatment in clinical practice of patients with mHSPC in Spain. These results emphasize the medical need of targeted treatments in these clinical settings.

Abstract
Numerous studies have unsuccessfully tried to unravel the definitive host of the coccidian parasite Besnoitia besnoiti. Cattle infections by B. besnoiti cause a chronic and debilitating condition called bovine besnoitiosis that has emerged in Europe during the last two decades, mainly due to limitations in its control associated with the absence of vaccines and therapeutical tools. Although the exact transmission pathways of B. besnoiti is currently unknown, it is assumed that the parasite might have an indirect life cycle with a carnivore as definitive host. Current lack of studies in wildlife might underestimate the importance of free-living species in the epidemiology of B. besnoiti. Thus, the aim of the present study is to assess the presence of Besnoitia spp. in free-ranging mesocarnivores in Spain. DNA was searched by PCR on faeces collected from wild carnivores as a first approach to determine which species could be considered as potential definitive host candidates in further research. For this purpose, a total of 352 faecal samples from 12 free-living wild carnivore species belonging to the Canidae, Felidae, Herpestidae, Mustelidae, Procyonidae and Viverridae families were collected in seven Spanish regions. PCR testing showed that Besnoitia spp. DNA was present in four faecal samples from red foxes collected in western Spain, an area with the greatest density of extensively reared cattle and associated with high incidence of bovine besnoitiosis in the country. To date, this is the first report of a B. besnoiti-like sequence (99.57% homology) from carnivore faeces in a worldwide context. Red foxes might contribute to the epidemiology of B. besnoiti, although further studies, mostly based on bioassay, would be needed to elucidate the accuracy and extent of these interesting findings.

Abstract
The occurrence and molecular diversity of the stramenopile eukaryote Blastocystis sp. was investigated by PCR and sequencing (Sanger and NGS) methods in 380 faecal specimens of free-living carnivores in Spain. Blastocystis sp. was confirmed in 1.6% (6/380) of the specimens analysed. Two samples from a common genet and a fox were successfully subtyped as ST7 by Sanger. Using NGS, ST14 was found in a fox and a European polecat, ST7 in a fox, and two additional foxes presented mixed infections of ST1/ST2/ST4 and ST1/ST2/ST7, respectively. Wild carnivore species could act as carriers of zoonotic Blastocystis subtypes.

Abstract
Information and communication technologies are transforming the way we understand health, via a hyper-connected world in which patients, professionals and society take on new challenges and roles. This change is creating an ecosystem called connected health, in which telemedicine acquires special importance when distance (not only geographical), is a critical factor. It can respond to financial, social or safety needs or questions of dignity, as is the case with prisoners when they are transferred handcuffed and under custody to hospitals. Bringing health services closer to patients who cannot autonomously travel contributes towards humanising healthcare. Tele-consultations, long-distance encounters between patients and health professionals, reduce the direct and social costs inherent to habitual clinical practice and are very highly valued by patients in prison. Despite its potential benefits in the prison setting, the implementation of telemedicine in Spain continues to be scarce and irregular, which, amongst other things, is due to a lack of awareness of this healthcare practice, the severe shortage of resources currently endemic to the prison health service system and the lack of interoperability solutions for clinical information between the healthcare administration and the prison health services, which unfortunately continue to depend on an organisation outside the healthcare ambit (the Ministry of Home Affairs), despite the legal provisions requiring them to be fully integrated into regional health services. The SARA (Administration Applications and Networks Systems) Network and the Reúnete© Service offer solid, secure, free technology is available to all prisons, to set in motion telemedicine programs at a nationwide level.

Abstract
Microsporidia comprises a diverse group of obligate intracellular parasites that infect a broad range of invertebrates and vertebrates. Among Microsporidia, Enterocytozoon bieneusi is the most frequently detected species in humans and animals worldwide bringing into question the possible role of animal reservoirs in the epidemiology of this pathogen. Although E. bieneusi is an emerging zoonotic pathogen able to infect many domestic and wild mammals that could act as reservoir of infection for humans and other animals, only few studies have documented its occurrence in wild carnivores. To determine the occurrence of E. bieneusi in wild carnivores, we examined 190 wild carnivores collected from different locations in Spain. Twenty-five fecal samples (13.2%) from three host species (European badger, beech marten, and red fox) were E. bieneusi-positive by PCR. Nucleotide sequence analysis of the ITS region revealed a high degree of genetic diversity with a total of eight distinct genotypes including four known (PtEbIX, S5, S9, and WildBoar3) and four novel (EbCar1-EbCar4) genotypes identified. Phylogenetic analysis showed that the four novel genotypes (EbCar1-EbCar4), S5, S9, and WildBoar3 clustered within the previously designated zoonotic Group 1. Our results demonstrate that human-pathogenic genotypes are present in wild carnivores, corroborating their potential role as a source of human infection and environmental contamination.

Abstract
There is a surprisingly scarce amount of epidemiological and molecular data on the prevalence, frequency, and diversity of the intestinal protozoan parasites Giardia duodenalis and Cryptosporidium spp. in wildlife in general and mesocarnivore species in particular. Consequently, the extent of the cyst/oocyst environmental contamination attributable to these wild host species and their potential implications for public veterinary health remain largely unknown. In this molecular epidemiological survey a total of 193 individual faecal samples from badgers (Meles meles, n=70), ferrets (Mustela putorius furo, n=2), genets (Genetta genetta, n=6), Iberian lynxes (Lynx pardinus, n=6), beech martens (Martes foina, n=8), mongooses (Herpestes ichneumon, n=2), otters (Lutra lutra, n=2), polecats (Mustela putorius, n=2), red foxes (Vulpes vulpes, n=87), wildcats (Felis silvestris, n=2), and wolves (Canis lupus, n=6) were obtained from road-killed, hunted, and accidentally found carcasses, and from camera-trap surveys or animals entering rescue shelters, during the period December 2003-April 2016. Investigated specimens were collected in five Spanish autonomous regions including Andalusia (n=1), Asturias (n=69), Basque Country (n=49), Castile-La Mancha (n=38), and Extremadura (n=36). The presence of cysts/oocysts was confirmed by PCR-based methods targeting the small subunit (ssu) ribosomal RNA gene of these parasite species. Genotyping of the obtained isolates were attempted at appropriate markers including the glutamate dehydrogenase (G. duodenalis) and the 60-kDa glycoprotein (C. parvum and C. ubiquitum) loci. Overall, G. duodenalis was detected in 8% (7/87) of red foxes, a single beech marten, and a single wolf, respectively. Cryptosporidium was identified in 3% (2/70) of badgers, 8% (7/87) of red foxes, a single genet, and a single mongoose, respectively. None of the nine G. duodenalis isolates generated could be genotyped at the assemblage/sub-assemblage level. Out of the nine Cryptosporidium isolates successfully characterized, three were identified as C. canis (one in a mongoose and two in red foxes), and three as C. parvum (one in a badger and three in red foxes). The remaining three isolates were assigned to C. felis (in a red fox), C. hominis (in a badger), and C. ubiquitum (in a red fox), respectively. Two additional Cryptosporidium isolates infecting a badger and a genet, respectively, were untypable. The red fox was confirmed as a suitable host of potentially zoonotic Cryptosporidium species, mainly C. parvum and C. ubiquitum. The high mobility and wide home range of red foxes, together with their increasing presence in urban and peri-urban settings, may led to the overlapping of sylvatic and domestic cycles of the parasite, and consequently, to an increased risk of cryptosporidiosis in production animals and humans. The detection of C. hominis oocysts in a badger raises the question of whether this finding represents a true infection or a sporadic event of mechanical passage of C. hominis oocyst of anthroponotic origin.

Abstract
This phase Ib/II trial combined the pan-deacetylase inhibitor panobinostat with chemotherapy followed by panobinostat maintenance in elderly patients with newly diagnosed acute myeloid leukemia. Patients with prior history of myelodysplastic syndrome were excluded and 38 evaluable patients were included in the study (median age: 71 years; range: 65-83). Study patients received an induction with idarubicin (8 mg/m(2) iv days 1-3) plus cytarabine (100 mg/m(2) iv days 1-7) plus panobinostat po at escalating doses (days 8, 10, 12, 15, 17 and 19) that could be repeated in non-responding patients. Patients achieving complete remission received a consolidation cycle with the same schema, followed by panobinostat maintenance (40 mg po 3 days/week) every other week until progression. Thirty-one patients were treated at the maximum tolerated dose of panobinostat in the combination (10 mg) with good tolerability. Complete remission rate was 64% with a time to relapse of 17.0 months (12.8-21.1). Median overall survival for the whole series was 17 months (5.5-28.4). Moreover, in 4 of 5 patients with persistent minimal residual disease before maintenance, panobinostat monotherapy reduced its levels, with complete negativization in two of them. Maintenance phase was well tolerated. The most frequent adverse events were thrombocytopenia (25% grades 3/4), and gastrointestinal toxicity, asthenia and anorexia (mainly grades 1/2). Five patients required dose reduction during this phase, but only one discontinued therapy due to toxicity. These results suggest that panobinostat is one of the first novel agents with activity in elderly acute myeloid leukemia patients, and suggest further investigation is warranted, particularly in the context of maintenance therapy. This trial is registered at clinicaltrials.gov identifier: 00840346.

Abstract
Infections by the protozoan enteroparasites Giardia duodenalis and Cryptosporidium spp are a major cause of morbidity in children attending day care facilities in developed countries. In this cross-sectional study, we aimed to estimate the occurrence and genotype frequencies of these pathogens in children attending day care centers in Majadahonda, Central Spain. To do so, single stool samples were obtained from 90 children and tested for the presence of G duodenalis and Cryptosporidium spp by conventional microscopy and immunochromatography. Positive results by these techniques were subsequently confirmed by immunofluorescence microscopy. G duodenalis-positive samples were subjected to molecular characterization studies by multilocus sequence-based genotyping of the glutamate dehydrogenase and β-giardin genes of the parasite. G duodenalis assemblages were confirmed by restriction fragment length polymorphism analyses and sequencing. A socioepidemiological questionnaire was used to identify variables potentially associated with giardiasis/cryptosporidiosis in the population of children under investigation. Overall, G duodenalis and Cryptosporidium spp were detected in 15.5% and 3.3% of stool samples, respectively. Giardiasis and cryptosporidiosis were found in 3/3 and 2/3 day care centers, respectively, affecting mainly infants aged 13 to 24 months. A total of 8 G duodenalis isolates were confirmed as subassemblage BIV, all of them belonging to asymptomatic children. Attempts to genotype Cryptosporidium isolates failed. None of the variables considered could be associated with higher risk of infection with giardiasis or cryptosporidiosis. These results clearly indicate that asymptomatic infections with G duodenalis and Cryptosporidium spp are frequent in <3-year-old children in Central Spain.

Abstract
Pre- or postexposure treatments against the filoviral hemorrhagic fevers are currently not available for human use. We evaluated, in a guinea pig model, the immunogenic potential of Kunjin virus (KUN)-derived replicons as a vaccine candidate against Ebola virus (EBOV). Virus like particles (VLPs) containing KUN replicons expressing EBOV wild-type glycoprotein GP, membrane anchor-truncated GP (GP/Ctr), and mutated GP (D637L) with enhanced shedding capacity were generated and assayed for their protective efficacy. Immunization with KUN VLPs expressing full-length wild-type and D637L-mutated GPs but not membrane anchor-truncated GP induced dose-dependent protection against a challenge of a lethal dose of recombinant guinea pig-adapted EBOV. The surviving animals showed complete clearance of the virus. Our results demonstrate the potential for KUN replicon vectors as vaccine candidates against EBOV infection.

Abstract
Several studies have demonstrated that the soil of public parks presents an important source of infection which has a significant impact on public health. Children are the main group affected by accidentally ingestion of contaminated soil. This study was performed in order to identify the presence of zoonotic parasites in dog and cat faecal and soil samples from public parks of Madrid, Spain. Six hundred twenty-five and seventy-nine soil and faecal samples (presumably from dogs and cats) respectively were collected from 67 parks. Intestinal parasites were identified in 27 parks (40.3%), which were contamined with Giardia sp. (19.4%), microsporidia (19.4%), Toxocara spp. (16.4%), Cryptosporidium sp. (6%), Entamoeba histolytica (3%) and Ancylostomidae (3%). Combinations of two or more intestinal parasites were found in 11 parks, and it was common to find Giardia and microsporidia together in samples. Intestinal parasites were detected in 18% (112/625) of soil samples. The most frequent parasite species found in the examined soil samples were Toxocara spp. (16.4%), followed by Giardia sp. (4.5%) and Strongyloides sp. larvae (3%). The zoonotic parasites found in the 79 faecal samples were Giardia sp. (17.7%), Cryptosporidium sp. (9%), E. histolytica (2.5%), Trichuris vulpis (1.3%), Toxascaris leonina (1.3%) and microsporidia spores (28%). Microsporidia characterization by amplification of DNA confirmed 10 samples as positive, eight for E. bieneusi and two for E. hellem by PCR. The role of those parasites in the environment are discussed.

Abstract
Interference of cefditoren (CDN) and amoxicillin/clavulanic acid (AMC) with biofilm production was studied using 11 Streptococcus pneumoniae isolates with minimum inhibitory concentrations (MICs) ranging from 0.015microg/mL to 0.5microg/mL for CDN and from 0.06microg/mL to 2microg/mL for AMC (except for one isolate with an AMC MIC of 8microg/mL) and 5 Haemophilus influenzae isolates with MICs of 0.03-0.06microg/mL for CDN and 0.5-16microg/mL for AMC. Slime production was assessed in antibiotic-free medium and with 0.03microg/mL CDN or 1/0.5microg/mL AMC by measuring the optical density at 450nm (OD(450)). Significantly lower mean OD(450) values were obtained for S. pneumoniae with antibiotics compared with controls (CDN, 0.088 vs. 0.118, P=0.003; and AMC, 0.095 vs. 0.112, P=0.003), with significant correlation between both antibiotics (r=0.752; P=0.008). Percent reduction in OD(450) values was higher for CDN compared with AMC (24.02% vs. 15.92%; P=0.008). For H. influenzae, significantly lower mean OD(450) values were obtained with CDN compared with controls (0.083 vs. 0.096; P=0.043) but not with AMC (0.086 vs. 0.095; P=0.08). Comparing percent reductions in S. pneumoniae versus H. influenzae for each antibiotic, no differences were found for AMC (15.92% vs. 9.40%; P=0.36), with a tendency for CDN (24.02% vs. 13.79%; P=0.069). Different beta-lactams may have different capabilities of interfering with S. pneumoniae biofilm development when tested under the same experimental conditions.

Abstract
INTRODUCTION Bacteremia frequently occurs after oral surgery and odontology procedures. Periodontitis may affect the incidence and bacterial spectrum of bacteremia. Periodontal disease may be a significant risk factor for the development of certain systemic diseases. This study has aimed to evaluate the frequency of aerobic and anaerobic bacteria in the bloodstream following scaling and root planing. MATERIAL AND METHODS Thirteen patients with generalized chronic periodontitis were included in the study. Two samples of peripheral blood were drawn for culture at different times: pre-treatment and immediately after odontology treatment (full-mouth scaling). RESULTS None of the 13 patients had bacteremia before the procedures. Bacteremia after scaling occurred in 10/13 (76.9 %) of periodontitis patients. The anaerobic bacteria (Prevotella spp., Micromonas micros and Fusobacterium nucleatum) were the most predominant microorganism. CONCLUSIONS Our findings suggest that periodontal procedures induce bacteremia and may represent risk of developing systemic complications. The use of antibiotic prophylaxis is crucial for its prevention.

Abstract
Biofilm production was assessed in 52 Staphylococcus epidermidis isolates from the catheters of 52 patients with catheter-related bloodstream infections (CR-BSI) and compared with 14 isolates from the skin of healthy volunteers by spectrophotometry. The isolates were classified as non- (G1), weak- (G2) or strong- (G3) slime producers based on optical density, and as producers and non-producers based on the results of the Congo red agar test. Differences (p = 0.012) in the proportion of G1, G2 and G3 among the isolates were found between catheter and healthy skin strains: there was a higher percentage of G1 types among the healthy skin strains (35.7 vs. 11.5%; p = 0.046) and a higher percentage of G3 types among the catheter isolates (44.2 vs. 0%; p = 0.001). No significant differences were found with the Congo red agar test. G3 is a phenotypic marker for CR-BSI.

Abstract
Two seroepidemiological surveys on canine leishmaniosis in stray dogs were performed annually in the Madrid region for 10 years (November 1996-April 2006). The presence of anti-Leishmania antibodies was detected by immunofluorescence antibodies test (cut off 1:100). The overall seroprevalence found in the 1,803 dogs studied was 7.8% (141 positive dogs). Seropositivity was not associated with either breed or sex. Statistical analysis revealed greater seroprevalence in groups of older dogs, indicating that the probability of exposure to the bite of sand flies infected with Leishmania infantum increased with age. The most important result was a high proportion of seropositivity for leishmaniosis (79.5%) among dogs without clinical signs of canine leishmaniosis. These data are very important because stray dogs can play an important role in the epidemiology of this zoonotic disease. Furthermore, the stray population could be useful sentinels to follow the progress of the disease in endemic areas.

Abstract
The phlebotomine sand fly Phlebotomus perniciosus is one of the main vectors of Leishmania infantum, responsible for human and canine leishmaniasis in the Mediterranean Basin. The objective of this study was to evaluate the repellent and insecticidal efficacy of imidacloprid 10% (w/v)/permethrin 50% (w/v) spot-on against sand flies (P. perniciosus) on dogs. The dogs used in this trial were laboratory-bred beagles: eight were impregnated with the solution (treated group), while the other eight were left untreated (control group). On day 0 the animals in the treatment group received 0.1 ml/kg body weight of the combination imidacloprid/permethrin spot-on. Dogs were exposed for 1h to about 100 female sand flies at weekly intervals for a period of 4 weeks, on day 1, 7, 14, 21, and 28 after applying the product. The repellency criterion was based on the feeding rate of sand flies in the treated compared to the untreated group. The insecticidal efficacy criterion was based on comparison of the survival rate of sand flies between the two groups. The product had an insecticidal efficacy on female sand flies of 53.2% (day 1), 49.4% (day 7), 15.1% (day 14), 13.2% (day 22), and 2.9% (day 29). The product showed a repellent effect of 97.7% (day 1), 96.3% (day 7), 96.5% (day 14), 92.7% (day 22), and 74.0% (day 29). Within the first week of application the insecticidal effect was significant; however it did not surpass 50%. On the other hand, the product showed a potent anti-feeding effect of over 90% during the first 3 weeks of this trial. Therefore, the application of this product every 3 weeks would be a good tool to significantly reduce sand fly bites over the period of transmission of vectorial diseases such as leishmaniasis and several arbovirosis such as Toscana virus.

Abstract
Using routine coprological methods, 1161 faecal samples from animal shelters located in Madrid (Spain) were analysed, showing a 28% prevalence for different intestinal parasites: Giardia duodenalis (7%), Cystoisopora spp. (3.8%), Toxocara canis (7.8%), Toxascaris leonina (6.3%), Ancylostomidae (4%), Trichuris vulpis (3.3%), Taenidae (2.9%) and Dipylidium caninum (0.9%). The therapeutic efficacies of mebendazole at a dose of 22 mg/kg once daily for 3 days, fenbendazole at a dose of 50 mg/kg once daily for 3 days and a drug combination of febantel-pyrantel-praziquantel at a dose of 15-5-5 mg/kg once were valuated and compared by collecting faecal samples on days 9 and 16 post-treatment from naturally infected dogs in field-trial conditions. From the infected dogs (321 dogs), 150 animals were selected for the study. Distribution randomly divided the animals into three study groups of ten dogs per parasite and per treatment group: group A, mebendazole; group B, fenbendazole and group C, febantel-pyrantel-praziquantel. The therapeutic efficacy against ascarids and ancylostomids (days 9-16) was very high (75-100%) for the three groups: for T. canis, 100% in group A, 80-100% in group B, 97-100% in group C; for T. leonina, 98-100% in group A, 100% in group B, 92-94% in group C and for ancylostomids, 100% in group A, 99-100% in group B, 90-100% in group C. On the other hand, the highest efficacy against Taenidae infections was in group B (90-100%), followed by groups C (73-91%) and A (70-90%).

Abstract
For centuries in Europe, population movements have contributed to ethnic groups, cultures, and consequently, inheritance mixing. There are certain genetic diseases such as hereditary hemochromatosis whose distribution is directly related to the population movements. The objective of the present investigation was to determine the C282Y and H63D mutation frequency of the HFE gene in a cohort study of 1,000 neonates in the Community of Madrid (Spain), thus contributing to the HFE gene mutations distribution research in Europe and establishing the origin of the mutations in Spain. The allelic frequency of C282Y mutation was 1.7% (CI 95% 1.1-2.3) and the H63D allele was present in 16.4% of chromosomes (CI 95% 14.8-18). In Spain, the presence of C282Y mutation and its distribution could be due more to Celtic than to Viking legacy, whereas it is assumed that the one in relation to the H63D variant occurred in the Basque Country during the Paleolithic Period.

Abstract
Dominant inherited beta-thalassemias describe those beta-thalassemia variants that result in a thalassemia intermediate phenotype in individuals who have inherited only a single copy of the abnormal beta gene. This form of thalassemia is characterized by moderately severe anemia with jaundice and splenomegaly; it is also characterized by the presence of inclusion bodies in the red blood cell precursors and has, therefore, previously been referred to as inclusion body beta-thalassemia. We describe a case of inclusion body beta-thalassemia in a 51-year-old Spanish male caused by a deletion of 11 bp (CD 131-134) in exon 3 of the beta-globin gene. The deletion of 11 bp in exon 3 of the beta-globin chain is predicted to produce an anomalous chain of 134 amino acids instead of the normal 146 with an extremely altered amino acid sequence from residues 131-134. Although this shortened variant would lead to a missing H helix, which is involved in alpha1beta1 contact and alpha1beta2 subunit interactions, the variant chain can still be bound to the heme group and acquire a secondary structure that is not suitable for the formation of stable dimers or tetramers and also less susceptible to proteolytic degradation. This is the first report of such a beta-thalassemia mutation.

Abstract
BACKGROUND AND OBJECTIVE Hemoglobin S (HbS) alpha-thalassemia together with ss-thalassemia and hemoglobins C, E and D are named common hemoglobinopathies. In this study, we analyzed the frequency of the association between alpha-thalassemia and HbS and its phenotypic expression. PATIENTS AND METHOD Since January 1995 to March 2003 we studied 83 cases of HbS, which were diagnosed by electrophoretic and chromatographic criteria. The molecular study was carried out by Southern blot with the restriction enzymes Bam HI and Bgl II and a (1.5 Kb Pst) and z (1.8 Kb Sac Y) probes. RESULTS 45 cases (54.2%) had a-thalassemia (36 -alpha3,7/aa; 1-alpha4,2/alphaalpha; 6 -alpha3,7/-alpha3,7; 1-alpha4,2/-alpha4,2); 36 had not alpha-thalassemia and in two cases there were a triplication of a genes. The patients with HbS heterozygote associated with alpha-thalassemia showed a percentage of HbS (p < 0.0001), CMV (p = 0.004), MCH (p = 0.002) and MCHC (p = 0.02) significantly lower than the cases of HbS without this association. However, no differences between both groups were found with regard to the rest of parameters analyzed (Hb p = 0.56; PVC p = 0.84; RDW p = 0.06; Reticulocytes p = 0.26; HbF p = 0.76; HbA2 p = 0.13). In the cases with a severe form of disease (HbS homozygote; HbS/Hb C; HbS/beta-thalassemia), patients with alpha-thalassemia had a number of leukocytes that was significantly lower than that of patients without alpha-thalassemia (p = 0.034). CONCLUSION An association between HbS and alpha-thalassemia was common (> 50%). Screening for this association is of great interest because the clinical expression in the cases of HbS homozigote will be modulated. This association must be suspected in cases of homozygous HbS in which levels of HbS are lower than expected.

Abstract
We describe, in a Spanish family with moderate microcytosis and hypochromia, a novel nondeletional alpha-thalassemia (thal) mutation localized on the alpha2-globin gene. DNA sequencing revealed a point mutation at codon 125 (CTG --> CGG) in the heterozygous state, that was confirmed by restriction analysis. The resulting variant, which causes a nondeletional alpha-thal, was named Hb Plasencia [alpha125(H8)Leu --> Arg (alpha2)] after the place of residence of the affected family.

Abstract
Seroprevalence of Toxoplasma gondii was tested for in 585 cats in different regions of Spain. Sera were tested by the indirect immunofluorescence antibody test (IFAT). Specific antitoxoplasma IgG (IFAT titer>or=1/80) were found in 189 of 585 (32.3%): 117 of 317 (36.9%) stray cats, 16 of 48 (33.3%) farm cats and 56 of 220 (25.5%) household cats. The overall prevalence was significantly higher in stray groups (36.4% of 365) than in household cats (25.5% of 220), higher in adult cats (>6 months old, 36.8% of 443) than in juvenile cats (<6 months old, 13.9% of 101), and higher in male stray cats (45.3% of 128) than in female stray cats (32% of 153). Prevalence of intestinal parasites was also analysed by a routine coprological method in 382 of the 585 cats. Intestinal parasites were found in 107 faecal samples (28%): 76 of 231 (32.9%) stray cats, 14 of 48 (29.2%) farm cats and 17 of 103 (16.5%) household cats. T. gondii oocysts were not found in any faecal samples analysed. The following prevalences of other intestinal parasites were found: Toxocara cati (18.3%), Toxascaris leonina (1.3%), Ancylostoma sp. (1%), Capillaria spp. (1.3%), Aelurostrongylus abstrusus (1%), Taenia like (3.7%), Dipylidium caninum (2.6%) and Cystoisospora spp. (6.3%).

Abstract
OBJECTIVE Thrombotic thrombocytopenic purpura (TTP) or Moschovitz' syndrome is rare and is even rarer in childhood. Clinically, it is characterized by microangiopathic hemolytic anemia, thrombocytopenia, neurologic abnormalities, fever and renal dysfunction. The etiology is still unknown, although different factors such as large von Willebrand factor multimers and prostacyclin have been implicated. The acute form is more frequent, and in most cases the course is fulminant if treatment is not initiated. Laboratory data typically reveal hemolytic anemia, with schistocytes on the peripheral smear, diminished serum haptoglobin, and thrombocytopenia. MATERIAL AND METHODS We present the clinical cases of two children, aged 4 and 7 respectively, with TTP, but with different evolution and treatment. Evolution was favorable in both patients. The first child recovered spontaneously. In the second plasmapheresis was required and produced remission of all the symptomatology. Normality has been maintained for 36 and 24 months respectively, and the children have presented no clinico-biological alterations.

Abstract
INTRODUCTION Haemophagocyte lymphohistiocytosis (HLH) is a hematological disorder, autosomal recessive and in which there is benign proliferation of histiocytes with intense phagocytic activity of hematopoietic cells. The clinical features include fever, pancytopenia, coagulation disorders, liver dysfunction, the presence of histiocytes and haemophagocytes in the bone marrow, lymph nodes, spleen and liver. The nervous system is always involved and sooner or later patients develop a nervous system disorder with variable symptoms which may include irritability, disorders of consciousness, convulsions, ataxia, nystagmus or signs of intracranial hypertension. CLINICAL CASE Onset of the disease showing purely neurological features is rare. We therefore describe the case of an 8 month old baby with HLH with a purely neurological condition involving irritability, horizontal rapid eye movements and vertical saccadic movements of both eyes and focal convulsive seizures. Initial complementary examinations were normal, except for study of the CSF with a lowered protein level and cells (monocytes). Finding hepatosplenomegaly and pallor, together with the laboratory investigations, made it advisable to do a bone marrow punch biopsy to detect haemophagocytes which would be diagnostic of HLH. In spite of chemotherapy there was rapid neurological deterioration, with alterations of the white matter and hydrocephaly which required insertion of a ventriculo-peritoneal shunt. The patient died when he was 10 months old. CONCLUSIONS The cases of HLH in which cerebromeningeal disorders alone precede systemic symptoms are extremely rare. Hence the interest in reporting this case, so that it may be borne in mind in other cases of acute neurological onset. In this case initially there was encephalitis alone, but this was rapidly followed by systemic complications.

Abstract
The most cases of splenic marginal zone lymphoma (SMZL) seem to respond favorably to splenectomy. The diagnosis of this lymphoma is mainly based on the recognition of a micronodular pattern of splenic involvement with marginal zone differentiation. However, it is possible to find so-called "marginal zone differentiation" in splenic involvement by other small B-cell lymphomas, particularly mantle cell lymphoma (MCL) and follicular lymphoma. We report a case of blastic MCL, large cell/anaplastic variant with a high level of clinical aggressiveness, showing biphasic cytology and a micronodular pattern which resembles SMZL. A single biopsy corresponding to this case shows two phases of tumoral progression in a MCL, a rare finding in MCL. In conclusion, the differential diagnosis of SMZL must take the possibility of a blastic MCL with biphasic cytology into account, as the case here.

Abstract
Splenic marginal zone lymphoma (SMZL) has been recognized as an entity defined on the basis of its morphological, phenotypic, and clinical characteristic features. Nevertheless, no characteristic genetic alterations have been described to date for this entity, thus making an exact diagnosis of SMZL difficult in some cases. As initial studies showed that chromosome region 7q22-32 is deleted in some of these cases, we analyzed a larger group of SMZL and other lymphoproliferative disorders that may partially overlap with it. To better define the frequency of 7q deletion in SMZL and further identify the deleted region, polymerase chain reaction analysis of 13 microsatellite loci spanning 7q21-7q36 was performed on 20 SMZL and 26 non-SMZL tissue samples. The frequency of allelic loss in SMZL (8/20; 40%) was higher than that observed in other B-cell lymphoproliferative syndromes (2/26; 7.7%). This difference was statistically significant (P < 0.05). The most frequently deleted microsatellite was D7S487 (5/11; 45% of informative cases). Surrounding this microsatellite the smallest common deleted region of 5cM has been identified, defined between D7S685 and D7S514. By comparative multiplex polymerase chain reaction analysis, we detected a homozygous deletion in the D7S685 (7q31.3) marker in one case. These results suggest that 7q31-q32 loss may be used as a genetic marker of this neoplasia, in conjunction with other morphologic, phenotypic, and clinical features. A correlation between 7q allelic loss and tumoral progression (death secondary to the tumor or large cell transformation) in SMZL showed a borderline statistical significance. The observation of a homozygous deletion in this chromosomal region may indicate that there is a tumor suppressor gene involved in the pathogenesis of this lymphoproliferative neoplasia.
