Prevalence study and phylogenetic analysis of group C porcine rotavirus in the Czech Republic revealed a high level of VP6 gene heterogeneity within porcine cluster I1

摘要

Group C rotavirus (RVC) has been described to be a causative agent of gastroenteritis in humans and animals. In the current study, the presence of porcine RVC was confirmed in 25.6 % of 293 porcine faecal samples collected from seven Czech farms. A significantly larger (p < 0.05) number of RVC-positive samples was detected in groups of finisher pigs and post-weaning piglets (4-12 weeks of age). Phylogenetic analysis of nine RVC-positive Czech strains and their comparison with available sequence data for the gene encoding RVC group antigen VP6 revealed two separate lineages within porcine cluster I1.
