Genetic and phylogenetic analyses of the first GIII.2 bovine norovirus in China.

ABSTRACT:

Background

Norovirus (NoV) is recognized as a highly contagious enteric pathogen of mammals, and bovine norovirus (BNoV) is associated with calf diarrhoea and has caused great economic losses in the cattle industry.

Results

Here, we describe a case of emerging calf diarrhoea on a cattle farm in Henan Province, Central China. BNoV was the only enteric pathogen detected in outbreaks according to tests for enteric viruses, bacteria and parasites. The complete genome of the newly identified strain CH-HNSC-2018 was successfully sequenced and found to be 7342 nucleotides in length. Sequence and phylogenetic analyses revealed that CH-HNSC-2018 belongs to GIII.2 BNoV. Further analysis of the major capsid protein demonstrated that it is separated by specific genetic distances from pr
