Abstract
Rotavirus A infects many mammalian species, including humans and causes diarrhea and gastrointestinal diseases. The virus also infects various bird species, including chickens, although information of avian rotavirus A (ARVA) infection in chicken populations in Japan is scarce. In this study, we report for the first time the whole-genome sequences of ARVA strains from Japanese chicken populations. The virus strains were inoculated to MA104 cells and cultured viruses were used to obtain the sequences with the MiSeq system, and genetic analysis demonstrated the genotype constellation of G19-P[30]-I11-R6-C6-M7-A16-N6-T8-E10-H8 of the Japanese chicken ARVA isolates. Phylogenetic analyses demonstrated that the VP1, VP2, VP3, VP4, VP7, NSP2, and NSP4 coding gene sequences of the Japanese strains were closer to those of Korean than the European ARVA strains, although such relationship was not clear for other genes. The data suggest that the Japanese ARVA strains and the ones in Korea have genetically close relationship, although the origin is not clear at this point. Further information including the whole-genome sequences of the Korean strains and sequences of other Japanese chicken ARVA strains will be necessary for elucidation of their origin.

Abstract
The antiviral activity of chlorine dioxide (ClO2) in liquid (ClO2 gas dissolved liquid) and gaseous state against avian influenza virus (AIV) and infectious bronchitis virus (IBV) was evaluated. To evaluate the effect of ClO2 in liquid state, suspension tests (10 ppm) and carrier tests in dropping / wiping techniques (100 ppm) were performed. In the suspension test, virus titers were reduced below the detection limit within 15 sec after treatment, in spite of the presence of an accompanying organic matter. In the carrier test by dropping technique, AIV and IBV were reduced to below the detection limit in 1 and 3 min, respectively. Following wiping technique, no virus was detected in the wiping sheets after 30 sec of reaction. Both viruses adhering to the carriers were also reduced by 3 logs, thereby indicating that they were effectively inactivated. In addition, the effect of ClO2 gas against IBV in aerosols was evaluated. After the exposure of sprayed IBV to ClO2 gas for a few seconds, 94.2% reduction of the virus titer was observed, as compared to the pre-treatment control. Altogether, hence, ClO2 has an evident potential to be an effective disinfectant for the prevention and control of AIV and IBV infections on poultry farms.

Abstract
The efficacy of ClO2 gas, as surface disinfectant at around 1,000 ppb against avian orthoavulaviruses type 1 (AOAV-1), infectious bronchitis virus (IBV), Escherichia coli (EC), and Salmonella Enteritidis (SE) was evaluated at the required level (≥99.9% reduction) on various surfaces. Exposing the surfaces to ClO2 gas for 1 hr reduced AOAV-1, except for rayon sheets which required 3 hr. However, 1 hr of exposure did not effectively reduced IBV titer. In the case of EC, glass plates and plastic carriers needed 1 hr of exposure, while rayon sheets required 2 hr. SE on rayon sheets required 1 hr exposure, but on the other tested surfaces showed inadequate reduction. Overall, ClO2 gas is an effective disinfectant for poultry farms.

Abstract
Rotavirus species A (RVA) is a pathogen mainly affecting children under five years old and young animals. The infection produces acute diarrhea in its hosts and, in intensively reared livestock animals, can cause severe economic losses. In this study, we analyzed all RVA genomic constellations described in animal hosts. This review included animal RVA strains in humans. We compiled detection methods, hosts, genotypes and complete genomes. RVA was described in 86 animal species, with 52% (45/86) described by serology, microscopy or the hybridization method; however, strain sequences were not described. All of these reports were carried out between 1980 and 1990. In 48% (41/86) of them, 9251 strain sequences were reported, with 28% being porcine, 27% bovine, 12% equine and 33% from several other animal species. Genomic constellations were performed in 80% (32/40) of hosts. Typical constellation patterns were observed in groups such as birds, domestic animals and artiodactyls. The analysis of the constellations showed RVA's capacity to infect a broad range of species, because there are RVA genotypes (even entire constellations) from animal species which were described in other studies. This suggests that this virus could generate highly virulent variants through gene reassortments and that these strains could be transmitted to humans as a zoonotic disease, making future surveillance necessary for the prevention of future outbreaks.

Evaluation of Virucidal Quantitative Carrier Test towards Bovine Viruses for Surface Disinfectants While Simulating Practical Usage on Livestock Farms. Microorganisms 2022; 10:microorganisms10071320.

Abstract
Livestock farming is affected by the occurrence of infectious diseases, but outbreaks can be prevented by effective cleaning and disinfection along with proper farm management. In the present study, bovine coronavirus (BCoV) and bovine rotavirus A (RVA) were inactivated using food additive-grade calcium hydroxide (FdCa(OH)2) solution, quaternary ammonium compound (QAC) and their mixture through suspension tests as the primary screening, and afterward via carrier tests using dropping or dipping techniques as the secondary screenings. Viruses in the aqueous phase can be easily inactivated in the suspension tests, but once attached to the materials, they can become resistant to disinfectants, and require longer times to be inactivated. This highlights the importance of thorough cleaning with detergent before disinfection, and keeping elevated contact durations of proper disinfectants to reduce viral contamination and decrease infectious diseases incidence in farms. It was also reaffirmed that the suspension and carrier tests are necessary to evaluate disinfectants and thus determine their actual use. Particularly, the mixture of QAC and FdCa(OH)2 was found to exhibit synergistic and broad-spectrum effects compared to their use alone, and is now recommended for use on livestock farms.

Abstract
Avian G18P[17] rotaviruses with similar complete genome constellation, including strains that showed pathogenicity in mammals, have been detected worldwide. However, it remains unclear how these strains spread geographically. In this study, to investigate the role of migratory birds in the dispersion of avian rotaviruses, we analysed whole genetic characters of the rotavirus strain RK1 that was isolated from a migratory species of birds [velvet scoter (Melanitta fusca)] in Japan in 1989. Genetic analyses revealed that the genotype constellation of the RK1 strain, G18-P[17]-I4-R4-C4-M4-A21-N4-T4-E4-H4, was highly consistent with those of other G18P[17] strains detected in various parts of the world, supporting the possibility that the G18P[17] strains spread via migratory birds that move over a wide area. Furthermore, the RK1 strain induced diarrhoea in suckling mice after oral gastric inoculation, indicating that at least some of the rotaviruses that originated from migratory birds are infectious to and pathogenic in mammals. In conclusion, it was demonstrated that migratory birds may contribute to the global spread of avian rotaviruses that are pathogenic in mammalian species.

Abstract
Fowl adenoviruses (FAdVs) and avian reoviruses (ARVs) are ubiquitous in poultry farms and most of them are not pathogenic, often cause damage to chicks. A total of 104 chicken fecal samples were collected from 7 farms of breeder chickens (layers and broilers) in Japan from 2019 to 2021, and yielded 26 FAdV plus 14 ARV isolates. By sequencing, FAdV isolates were classified as FAdV-1, 5 and 8b. ARV isolates were classified as genotype II, IV and V. These results suggest that FAdVs and ARVs are resident in the breeder chicken farms in Japan.

Abstract
Slightly acidic hypochlorous acid waters (SAHWs) with pH of 5.2-5.8 containing different concentrations of free available chlorine - 62, 119, 220, 300, and 540 ppm (SAHW-62, -119, -220, -300, and -540, respectively) - were evaluated for their virucidal activity toward a low pathogenic H7N1 avian influenza virus (AIV) and an infectious bronchitis virus (IBV) in suspension, abiotic carrier, and direct spray tests, with the presence of organic materials. In the carrier test, the dropping and wiping techniques were performed toward viruses on carriers. In the suspension test, SAHW-62 could decrease the viral titer of both AIV and IBV by more than 1000 times within 30 s. With the dropping technique, IBV on carriers showed high resistance to SAHW, while AIV on plastic carrier was inactivated to an effective level (≧3 log virus reduction) within 1 min. With the wiping technique, SAHW-62 could inactivate both AIV and IBV on wiped plastic carriers to an effective level within 30 s. However, SAHW-220 could not inactivate IBV in the wiping rayon sheet to an effective level. In the direct spray test, sprayed SAHW-300 within 10 min, and SAHW-540 within 20 min, inactivated AIV and IBV on the rayon sheets to undetectable level, respectively. Our study indicates that the usage of wipes with SAHW could remove viruses from plastic carriers, while viruses remained in the wipes. Besides, a small volume of sprayed SAHW was effective against the viruses on the rayon sheets for daily cleaning in the application area. The findings we obtained concerning IBV might basically be applicable in relation to SARS-CoV-2, given the resemblance between the two viruses.

Abstract
The diseases with watery droppings (diarrhea and/or polyuria) can be considered some of the most severe health problems in domestic pigeons of various ages. Although they do not always lead to bird death, they can contribute to poor weight gains and hindered development of young pigeons and, potentially, to poor racing results in sports birds. The gastrointestinal tract disorders of pigeons may be of various etiology, but some of the causative agents are viral infections. This review article provides information collected from scientific reports on RNA-viruses belonging to the Astroviridae, Picornaviridae, and Coronaviridae families; the Avulavirinae subfamily; and the Rotavirus genus that might be implicated in such health problems. It presents a brief characterization, and possible interspecies transmission of these viruses. We believe that this review article will help clinical signs of infection, isolation methods, occurrence in pigeons and poultry, systemize and summarize knowledge on pigeon enteropathogenic viruses and raise awareness of the importance of disease control in pigeons.

Abstract
Decontamination of pathogens on surfaces of substances is very important for controlling infectious diseases. In the present experiments, we tested various
disinfectants in aqueous phase as well as on plastic surface carrying a viral inoculum, through dropping and wiping decontamination techniques, comparatively,
so as to evaluate virucidal efficacies of those disinfectants toward an avian coronavirus (infectious bronchitis virus: IBV). We regard this evaluation system
applicable to SARS-CoV-2. The disinfectants evaluated were 0.17% food additive glade calcium hydroxide (FdCa(OH)2) solution, sodium hypochlorite at
500 or 1,000 ppm of total chlorine (NaClO-500 or NaClO-1,000, respectively), NaClO at 500 ppm of total chlorine in 0.17% FdCa(OH)2 (Mix-500) and
quaternary ammonium compound (QAC) diluted 500-fold in water (QAC-500). In the suspension test, all solutions inactivated IBV inoculum that contained 5% fetal
bovine serum (FBS) under detectable level within 30 sec. In the carrier test, all solutions, except NaClO-500, could inactivate IBV with 0.5% FBS on a carrier
to undetectable level in the wiping-sheets and wiped-carriers. We thus conclude that suspension and carrier tests should be introduced to evaluate disinfectants
for the field usage, and that this evaluation system is important and workable for resultful selection of the tested disinfectants against avian coronavirus and
SARS-CoV-2 on surfaces, particularly on plastic fomite.

Abstract
Retrospective analysis of pigeon necropsy submissions to the California Animal Health and Food Safety Laboratory System from 2000 to 2018 revealed 14 submissions diagnosed with rotavirus A hepatic necrosis or "reoviruslike" viral hepatitis. Nine of the 14 submissions (64%) occurred in 2018. Submissions were racing pigeons and squab breeders from flocks with increased mortality. Juvenile and adult pigeons were submitted with a history of depression, diarrhea, regurgitation, labored breathing, and weakness. Flock morbidity peaked at 80% and mortality at 28%. The most consistent findings on postmortem examination were variably congested, mottled, and enlarged livers and spleens. Microscopically, mild to severe hepatic necrosis was observed with variable bile duct hyperplasia, sinusoidal congestion, hemosiderosis, and portal lymphoplasmacytic inflammation. Rotavirus A was detected in hepatocytes and inflammatory cells by immunohistochemistry. Negative-stain electron microscopy identified viral particles consistent with a member of Reoviridae in all negatively stained liver homogenates. Eleven cases were analyzed by reverse transcriptase-PCR targeting rotavirus A viral protein (VP) 6 and VP7 genes. Subsequent phylogenetic analysis of the VP6 and VP7 sequences compared to published Chinese, Nigerian, and German rotavirus A VP6 and VP7 sequences demonstrated the formation of two and three distinct clades, respectively. To the authors' knowledge, rotavirus A hepatic necrosis in pigeons has not been previously reported in the United States and represents a significant emerging disease for the pigeon industry due to the potential for high flock mortality and lost production.

Abstract
A novel Group A rotavirus, first identified clinically in racing, feral and fancy pigeons in Western Australia, had spread throughout Australia by March 2017. In December 2016, the putative index case of rotavirus in racing pigeons in the state of Victoria was confirmed at a regional bird sale, with rapid spread to peri-urban Melbourne, the capital city. A survey sent to approximately 400 Victorian pigeon fanciers identified eight (of 85 respondents) with a confirmed rotavirus infection in their loft(s). If a fancier had purchased live birds, either from the regional sale or from another source, there was a 13%-38% increased likelihood of the loft subsequently being confirmed rotavirus-positive. An increased loft-level risk of rotavirus was also positively associated with the number of neighbouring lofts within a 5-km radius of a home loft. It was concluded that rotavirus was primarily transmitted beyond the Victorian index case through the movement of live birds into a loft, either deliberately through bird purchase and/or inadvertently through the entry of pigeons from neighbouring lofts. As pigeon racing inherently requires consistent contact between birds from different lofts, vaccination is recommended as a primary method of rotavirus control in this unique industry.

Abstract
In 1981, a new virus (virus 132) was described for the first time with morphological and biochemical similarities to rotaviruses (RVs), but without antigenic similarity to any of the previously known rotavirus groups. Subsequently, it was re-designated as D/132, and formed a new serogroup among rotaviruses, the group D rotavirus (RVD). Since their identification, RVs are the leading cause of enteritis and diarrhea in humans and various animal species, and are also associated with abridged growth, particularly in avian species. Recently, RVD has been suggested to play a role in the pathogenesis of runting and stunting syndrome (RSS), alongside other viruses such as reovirus, astrovirus, coronavirus, and others, all of which cause colossal economic losses to the poultry industry. RVD has been reported from several countries worldwide, and to date, only one complete genome sequence for RVD is available. Neither an immunodiagnostic nor a vaccine is available for the detection and prevention of RVD infection. Despite our growing understanding about this particular group, questions remain regarding its exact prevalence and pathogenecity, and the disease-associated annual losses for the poultry industry. Here, we describe the current knowledge about the identification, epidemiology, diagnosis, and prevention of RVD in poultry.

Abstract
To obtain complete genome sequences of turkey rotavirus A strains Ty-1 and Ty-3, we sequenced the gene segments that had not been decoded previously. The genotype constellations of the respective strains were determined to be G17-P[38]-I4-R4-C4-M4-A16-N4-T4-E4-H4 and G7-P[35]-I4-R4-C4-M4-A16-N4-T4-E11-H14. Notably, their VP4 and NSP5 genes were classified into novel genotypes.

Abstract
Rotaviruses (RVs) are among the leading causes of enteritis and diarrhea in a number of mammalian and avian species, and impose colossal loss to livestock and poultry industry globally. Subsequent to detection of rotavirus in mammalian hosts in 1973, avian rotavirus (AvRV) was first reported in turkey poults in USA during 1977 and since then RVs of group A (RVA), D (RVD), F (RVF) and G (RVG) have been identified around the globe. Besides RVA, other AvRV groups (RVD, RVF and RVG) may also contribute to disease. However, their significance has yet to be unraveled. Under field conditions, co-infection of AvRVs occurs with other infectious agents such as astroviruses, enteroviruses, reoviruses, paramyxovirus, adenovirus, Salmonella, Escherichia coli, cryptosporidium and Eimeria species prospering severity of disease outcome. Birds surviving to RV disease predominantly succumb to secondary bacterial infections, mostly E. coli and Salmonella spp. Recent developments in molecular tools including state-of-the-art diagnostics and vaccine development have led to advances in our understanding towards AvRVs. Development of new generation vaccines using immunogenic antigens of AvRV has to be explored and given due importance. Till now, no effective vaccines are available. Although specific as well as sensitive approaches are available to identify and characterize AvRVs, there is still need to have point-of-care detection assays to review disease burden, contemplate new directions for adopting vaccination and follow improvements in public health measures. This review discusses AvRVs, their epidemiology, pathology and pathogenesis, immunity, recent trends in diagnostics, vaccines, therapeutics as well as appropriate prevention and control strategies.

Abstract
Group A rotaviruses (RVA) are a major cause of viral diarrhea in the young of mammals and birds. RVA strains with certain genotype constellations or VP7-VP4 (G-P) genotype combinations are commonly found in a particular host species, whilst unusual or exotic RVAs have also been reported. In most cases, these exotic rotaviruses are derived from RVA strains common to other host species, possibly through interspecies transmission coupled with reassortment events, whilst a few other strains exhibit novel genotypes/genetic constellations rarely found in other RVAs. The epidemiology and evolutionary patterns of exotic rotaviruses in humans have been thoroughly reviewed previously. On the other hand, there is no comprehensive review article devoted to exotic rotaviruses in domestic animals and birds so far. The present review focuses on the exotic/unusual rotaviruses detected in livestock (cattle and pigs), horses and companion animals (cats and dogs). Avian rotaviruses (group D, group F and group G strains), including RVAs, which are genetically divergent from mammalian RVAs, are also discussed. Although scattered and limited studies have reported rotaviruses in several exotic animals and birds, including wildlife, these data remain to be reviewed. Therefore, a section entitled "rotaviruses in exotic animals" was included in the present review.

Abstract
This study was undertaken to develop and validate a multiplex reverse transcription-polymerase chain reaction (mRT-PCR) for simultaneous detection of avian rotavirus, turkey astrovirus-2 (TAstV-2), and avian reovirus. Primers targeting the conserved regions of NSP4 gene of avian rotavirus, polymerase gene of TAstV-2, and S4 gene of avian reovirus were used. The position of bands at 630, 802, and 1120 base pairs on agarose gel confirmed the presence of rotavirus, TAstV-2, and reovirus, respectively. This mRT-PCR was found to be specific as no amplification was observed with avian influenza virus, Newcastle disease virus, turkey coronavirus, avian metapneumovirus, and intestinal contents of uninfected turkey poults. Intestinal contents of poults from flocks suspected of exhibiting "poult enteritis syndrome" were pooled and tested. Of the 120 pooled samples tested, 70% were positive for TAstV-2, 45% for avian rotavirus, and 18% for avian reovirus. These three viruses were detected alone or in different combinations. Of the samples tested, 20% were negative for these three viruses, 38% were positive for a single virus (TAstV or rotavirus or reovirus), and 42% were positive for two or three viruses. This single-tube mRT-PCR assay has the potential to serve as a rapid diagnostic method for the simultaneous detection of the three enteric viruses in turkeys.

Abstract
A total of 516 slaughter-age ostrich sera were collected in Japan during 2006-2009. Sixty-one of five hundred and sixteen were positive by virus neutralization (VN) test and the titer of most positive samples was low level. Within the 61 positive sera, 35 sera were collected from unvaccinated ostriches. This result implies that these ostriches might have been infected naturally with low-virulent Newcastle disease virus (NDV). Within the 455 negative samples, 125 samples were from vaccinated ostriches. Since ostrich farmers use live attenuated vaccines, it is reasonable that the titer decreased to below detection level by 1 or 1.5 year-old. The above data indicate that NDV has infiltrated into ostrich farms in Japan, and that the efficacy of ostrich ND vaccination is often time-limited.

Abstract
Avian rotaviruses (AvRVs) represent a diverse group of intestinal viruses, which are suspected as the cause of several diseases in poultry with symptoms of diarrhoea, growth retardation or runting and stunting syndrome (RSS). To assess the distribution of AvRVs in chickens and turkeys, we have developed specific PCR protocols. These protocols were applied in two field studies investigating faecal samples or intestinal contents of diseased birds derived from several European countries and Bangladesh. In the first study, samples of 166 chickens and 33 turkeys collected between 2005 and 2008 were tested by PAGE and conventional RT-PCR and AvRVs were detected in 46.2%. In detail, 16.1% and 39.2% were positive for AvRVs of groups A or D, respectively. 11.1% of the samples contained both of them and only four samples (2.0%) contained rotaviruses showing a PAGE pattern typical for groups F and G. In the second study, samples from 375 chickens and 18 turkeys collected between 2009 and 2010 were analyzed using a more sensitive group A-specific and a new group D-specific real-time RT-PCR. In this survey, 85.0% were AvRV-positive, 58.8% for group A AvRVs, 65.9% for group D AvRVs and 38.9% for both of them. Although geographical differences exist, the results generally indicate a very high prevalence of group A and D rotaviruses in chicken and turkey flocks with cases of diarrhoea, growth retardation or RSS. The newly developed diagnostic tools will help to investigate the epidemiology and clinical significance of AvRV infections in poultry.

Abstract
Serum samples from 191 ostriches (Struthio camelus) in Japan were tested for antibodies to Newcastle disease virus (NDV) and avian influenza virus (AIV). Twenty-two (12%) contained NDV-specific neutralizing antibodies by a virus-neutralization (VN) test without vaccination. Antibodies to AIV were not detected in the any sera by an agar gel precipitation test. Seven serum samples that had vaccinated with live NDV by eye drop were all positive by the VN test at 1 month post vaccination. A haemagglutination inhibition (HI) test for NDV seemed not to be suitable for ostriches because of non-specific agglutination of chicken red blood cells. No haemagglutinating viruses were isolated. This is the first report on detection of antibodies against NDV in ostriches in Japan.

Abstract
The intestinal tract and intestinal contents were collected from 34 stunted, 5-to-14-day-old broiler chicks from eight flocks with runting and stunting syndrome (RSS) in Northern Germany to investigate intestinal lesions and the presence of enteric pathogens with a special focus on rotaviruses (RVs). Seven chicks from a healthy flock were used as controls. Severe villous atrophy was seen in chicks from six flocks with RSS but not in the control flock. Lesions were often "regionally" distributed in the middle-to-distal small intestine. Transmission electron microscopy (TEM), polyacrylamide-gel electrophoresis (PAGE), reverse-transcriptase polymerase chain reaction (RT-PCR), and seminested RT-PCR were used for detection and characterization of RVs. The PAGE allows discrimination of different RV groups, and the RT-PCR was used to verify the presence of group (gp) A RVs. RVs were detected (by all methods) in 32 of 34 chicks from the flocks with RSS. By TEM (negative staining), RV particles were observed in intestinal contents of 28 chicks from the flocks with RSS. PAGE analysis showed four RV groups: gpA, gpD, gpF, and gpG. Group A RVs were detected in four chicks from two flocks with RSS, without intestinal lesions. GpD RVs were detected in 12 chicks of five flocks with RSS, 10 of them with severe villous atrophy. GpF RVs were confirmed in four chicks from three flocks with RSS and in two birds in the control flock. GpG RVs were verified in two chicks from two flocks with RSS, one with, and one without, intestinal lesions. At present, PCR methods are only available for detection of gpA RVs. Using RT-PCR, gpA RVs were identified in samples from 22 chicks including samples of two chicks from the control flock. Statistical analysis revealed a positive correlation between presence of gpD RV and severe villous atrophy in flocks with RSS. The results suggest that gpD RV plays a major role in the pathogenesis of RSS.

Abstract
Three ostriches (Struthio camelus) were immunized with commercially available live and killed Newcastle disease (ND) vaccines for chickens and the antibody responses to the ND vaccines were evaluated by a virus-neutralization (VN) test. Primary vaccination with the live vaccine, B1, by eye drop was followed with two shots of alum-precipitated killed vaccine via subcutaneous injection in the neck. As a final booster, another live vaccine, Clone 30, was used by eye drop. A VN antibody titer, more than 1:10 was observed for 6 months. This is the first report on the use of a live vaccine by eye drop as a booster in ostriches as well as evaluating responses to ND vaccines using the VN test in this avian species.

Abstract
Rotavirus particles were identified in the intestinal content of a 35-day-old stunted chicken. The virus was isolated, RNA pattern was analysed and the viral genome segment 6 was sequenced. In particular, the sequence data showed a very close similarity to the chicken rotavirus isolate Ch-1 (99.2% amino acid homology), this is distantly related to all known avian rotaviruses and supports the existence of different VP6 types amongst avian group A rotaviruses.

Abstract
We determined the NSP4 sequences of turkey rotavirus strains Ty-1 and Ty-3 and a chicken rotavirus, strain Ch-1, and compared these sequences with those of a pigeon rotavirus, strain PO-13, and mammalian rotaviruses. The turkey strains and PO-13 were found to be closely related (90-97% homologies). Ch-1 NSP4 was distinctly different from other avian rotavirus NSP4s, with 78-79% homologies. The NSP4 sequences of avian rotaviruses were found to be 6-7 amino acids shorter than those of all mammalian strains and to have considerably low identities (31-37%) with them. Therefore, it seems highly likely that the NSP4 genes of avian rotaviruses are classified into two NSP4 genotypes distinct from those of mammalian rotaviruses. The enterotoxin domain in NSP4 is conserved in terms of its sequential and structural properties despite extremely low homologies in the full lengths of NSP4s in avian and mammalian rotaviruses.

Abstract
Avian rotavirus NSP4 glycoproteins expressed in Escherichia coli acted as enterotoxins in suckling mice, as did mammalian rotavirus NSP4 glycoproteins, despite great differences in the amino acid sequences. The enterotoxin domain of PO-13 NSP4 exists in amino acid residues 109 to 135, a region similar to that reported in SA11 NSP4.

Abstract
It has been suggested that group A avian rotaviruses can be transmitted to mammals, but there is no direct evidence that such viruses induce disease in mammals. Suckling mice were orally inoculated with two avian rotaviruses. A pigeon rotavirus, PO-13, was found to induce diarrhea, but a turkey rotavirus, Ty-3, did not. The diarrhea induced by PO-13 was dependent on the age of the mouse. In histopathological examinations, antigens of PO-13 were sporadically detected in absorptive cells in the ileum, and lesions were observed as ballooning degenerations of absorptive cells in a region from the duodenum to the ileum. However, the rotavirus antigen was not detected in the majority of these degenerative cells. These results indicated that PO-13 could infect and induce diarrhea in suckling mice. This is the first evidence of an avian rotavirus being experimentally transmissible to a mammal.

Abstract
Chicken egg yolk immunoglobulins (yIg) specific against bovine rotavirus (BRV) serotypes 6 (strain Shimane) and 10 (strain KK-3) were used for oral passive immunization of suckling mice against experimental BRV challenge. The protective capacity of the antibody preparation was tested using different concentrations of yIg against a challenge dose of 10(7.5) TCID50 for Shimane and 10(7.0) TCID50 for KK-3 strain. There was a significant homotypic (P < 0.05) and heterotypic (P < 0.01) protection using 160 anti-Shimane or 160 anti-KK-3 neutralizing antibody titer (NAT) compared to control mice given yIg derived from eggs of mock-immunized (control) hens. The titer of infectious BRV recovered from intestinal tissue or luminal chyme decreased with increasing homotypic yIg NAT. A decrease in degree and duration of BRV antigen localization in the villus epithelial lining was observed in mice treated with homotypic yIg at optimum dose for prevention of diarrhea. The NAT in sera of challenged mice increased with decreasing NAT in the yIg given before challenge suggesting that protection was dose-dependent. The present findings indicate that a passive protection could be achieved by the use of yIg against BRV-induced diarrhea in this murine model.

Abstract
With measles virus cDNA of the avirulent vaccine strain AIK-C, two cDNAs of H or F genes were amplified by the polymerase chain reaction. The amplified cDNAs were inserted respectively to the baculovirus transfer vector pAcYM1 derived from the nuclear polyhedrosis virus of Autographa californica (AcNPV). After co-transfection of the transfer vectors with AcNPV DNA to Spodoptera frugiperda cells, recombinant baculoviruses were screened by plaque assay, and the viruses containing H-cDNA or F-cDNA were named H-AIK or F-AIK, respectively. By Western blot analyses, the band around 80 kDa and some smaller bands were appeared in the H-AIK infected S. frugiperda cells, and the band around 40 kDa was detected in the F-AIK infected cells. Immunofluorescence studies on unfixed S. frugiperda cells infected with H- or F-AIK recombinants showed that both antigens were transported to the cell surface. When green monkey red blood cells were added to the recombinant infected cells, H-AIK infected cells showed haemadsorption, and cells infected with F-AIK lysed the red blood cells. The recombinant proteins elicited the neutralizing antibodies against measles virus.
