Detection and genome characterization of bovine kobuvirus (BKV) in fecal samples from diarrheic calves in Quebec, Canada

Transbound Emerg Dis. 2021 Mar 31. doi: 10.1111/tbed.14086. Online ahead of print.ABSTRACTKobuviruses are known to infect the gastrointestinal tract of different animal species. Since its discovery in 2003, bovine kobuvirus (BKV) has been identified in fecal samples from diarrheic cattle in many countries, but only recently in North America. Although its possible role as an agent of calf diarrhoea remains to be determined, evidence is mounting. Our study reports for the first time the detection of BKV in fecal samples from diarrheic calves raised in Quebec, Canada. BKV was more commonly identified than eight known and common enteric calf pathogens. Further sequence analysis revealed that Canada BKV strain 1043507 was more closely correlated with the US BKV IL35164 strain than other BKV strains with complete genome. Continued surveillance and genomic characterization are needed to monitor BKV in the cattle around the world.PMID:33788413 | DOI:10.1111/tbed.14086
