OBJECTIVE: To study the prevalence of bovine group A rotavirus (GARV) and bovine coronavirus (BCoV) in diarrheic feces from calves and the sensitive's parameters such as age group and sex. METHODS: Feces samples from 82 diarrheic dairy calves from farms around Tiaret (Western Algeria) were collected. These samples were tested by ELISA assay. RESULTS: The results showed that the prevalence of rotavirus and coronavirus infection are 14.63% (12.2% alone and 2.43% associated with bovine coronavirus) and 20.73% (18.3% alone and 2.43% associated with GARV), respectively. CONCLUSIONS: The present study demonstrates that the both BCoV and GARV are involved in the neonatal calves' diarrhea, where the frequency of BCoV is clearly higher than that of GARV.
