Abstract
Calf diarrhoea is one of the major problems in cattle farming with high morbidity and mortality in herds. Two enteric viruses,
bovine rotavirus (BRV) and bovine coronavirus (BCoV), are the leading cause of gastroenteritis in young calves, whereas
picobirnaviruses (PBVs) are often associated with diarrhoea. In the present study, the faecal specimens of 127 diarrhoeic
bovines (less than 1-month-old) were employed to investigate the infection frequencies of these three pathogens. Results
indicated that frequencies of BRV and BCoV in diarrhoeic calves were 38.58% and 29.92%, respectively. The 7.08% of
bovine calf samples (9 out of 127) were found to be positive for PBV genogroup I. Sequence analysis further revealed the
high genetic heterogeneity within representative PBV sequences. Additionally, both PBV-BCoV (n=2) and BCoV-BRVPBV (n=1) co-infections were detected in bovine calves for the frst time. Consequently, our fndings pointed out the highly
divergent nature of PBVs without regard to exact host or territory and the occasional co-existence with other enteric agents.
