Abstract

Bovine rotavirus C (RVC), bovine coronavirus (BCV), and coccidia were detected in a herd of calves with diarrhea at a public ranch in Tochigi Prefecture from May to June 2016. A significant increase in anti-RVC and -BCV titers were also observed in the calf herd. Moreover, 100 serum samples collected at 12 farms in Tochigi Prefecture were subjected to an indirect immunofluorescence assay to investigate bovine RVC antibody prevalence in dairy calves from a variety of young age groups. Antibodies against RVC were detected at 83% of the farms. Our data also showed that about 50% of calves from 12 to 23 months of age were infected with bovine RVC. In this study, we demonstrate that bovine RVC is an important causative agent of diarrhea in adult cows as well as calves.
