...disease models for human rotavirus, human norovirus and human enterovirus 71 using neonatal gnotobiotic pigs. The differences between germ-free and normal animals in the maturation status of immune systems caused by the lack of gut microbiota can be minimized by establishing human-gut-microbiota transplanted gnotobiotic pig models. Given the advantages of gnotobiotic pig models, it is expected that they will be used more widely in biomedical research for studi...

...ions for the presence of rotavirus (RVA, RVD, and RVF), avian coronavirus (ACoV), and avian astrovirus (AAstV), using PCR reactions followed by nucleotide sequencing and analysis. Twenty-nine pools (29/59; 49%) appeared positive for AAstV, 6 pools (6/59; 10%) were positive for RVD, forty-three pools (43/59; 72.8%) were positive for ACoV, and twenty-four pools (24/59; 40.67%) presented concomitant viral infections of two or three investigated agents. The relati...

...nalysis of unusual human rotavirus VP4 genotype detected in Moroccan children fully vaccinated with Rotarix™. After RNA virus extraction, the rotavirus VP7 and VP4 genes were amplified. The DNA was purified, sequenced and genotypes were determined using the RotaC online classification tool. A phylogenetic tree was constructed using the Maximum Likelihood method applying the Tamura 3-parameter model in MEGA 6.06 package...

The detection was done by ELISA and indirect fluorescent antibody technique (FAT) as well as molecular method as real-time quantitative reverse transcriptase PCR (RT-qPCR) from samples collected during neonatal diarrhea. Six out of forty tested samples were found positive for

...hea virus (BVDV), bovine rotavirus (BRV), and bovine coronavirus (BCV) have increased calves morbidity and mortality in Hebei Province. To detect these three pathogens simultaneously, we designed specific primers based on the conserved gene sequences of the three pathogens available in GenBank. After optimization of the reaction conditions and system, we successfully established a novel multiplex PCR method for detection of the aforementioned three pathogens. ...

After preparation of fecal samples and inoculation on MA 104 cell line for five passages, eight isolates were successfully isolated with a clear and reproducible CPE on the inoculated cells. The isolates were identified antigenically using VP6 monoclonal antibodies (MAbs) based antigens capture ELISA that able to de...
