Epidemiological survey of enteric viruses in wild boars in the Czech Republic: First evidence of close relationship between wild boar and human rotavirus A strains

Publication date: Available online 4 August 2016 Source:Veterinary Microbiology Author(s): Romana Moutelíková, Lucie Dufková, Jiří Kamler, Jakub Drimaj, Radim Plhal, Jana Prodělalová Population of wild boar is increasing in the whole Europe, the animals migrate close to human habitats which greatly increases the possibility of natural transmission between domestic animals or humans and wild boars. The aim of the study was to estimate in population of free-living wild boar in the Czech Republic the prevalence of enteric viral pathogens, namely rotavirus groups A and C (RVA and RVC), porcine reproductive and respiratory syndrome virus (PRRSV), and members of family Coronaviridae (transmissible gastroenteritis virus − TGEV, porcine epidemic diarrhea virus − PEDV, porcine respiratory coronavirus − PRCV, and porcine hemagglutination encephalomyelitis virus − PHEV) and Picornaviridae,(teschovirus A − PTV, sapelovirus A − PSV, and enterovirus G − EV-G). In our study, stool samples from 203 wild boars culled during hunting season 2014-2015 (from October to January) were examined by RT-PCR. RVA was detected in 2.5% of tested samples. Nucleotide analysis of VP7, VP4, and VP6 genes revealed that four RVA strains belong to G4P[25]I1, G4P[6]I5, G11P[13]I5, and G5P[13]I5 genotypes and phylogenetic analysis suggested close relation to porcine and human RVAs. The prevalence of RVC in wild boar population reached 12.8%, PTV was detected in 20.2%, PSV in 8.9%, and ...
