Resumo: | ABSTRACT: Calf diarrhea causes substantial economic losses in the cattle industry worldwide. Bovine rotavirus A (RVA) is the main viral agent that leads to enteric infection and diarrhea outbreaks in calves throughout the world. The aim of this retrospective (2006-2015) study was to determine the frequency of RVA detection in diarrheic fecal samples from beef and dairy calves from the three main cattle-producing regions of Brazil. Diarrheic fecal samples (n=1,498) of 124 beef and 56 dairy cattle herds from the Midwest, South, and Southeast geographical regions of Brazil were evaluated using the silver-stained polyacrylamide gel electrophoresis (ss-PAGE) technique. RVA double stranded-RNA was identified by the ss-PAGE technique in 410 (27.4%) fecal samples. The frequency of positive samples found in beef calves (31.9%; 328/1,027) was higher than the frequency found in diarrheic fecal samples from dairy calves (17.4%; 82/471). RVA infection was identified in calves from the three Brazilian geographical regions analyzed. However, the frequency of positive diarrheic calves in the Midwest region (39.4%), predominantly beef calves, was higher than in the South (19.4%) and Southeast (17.6%) regions. The temporal distribution of RVA-infected calves evaluated by two five-year periods (2006-2010, 24.5%; 2011-2015, 28.8%) demonstrated a very similar frequency of RVA in both periods. Considering the wide regional and temporal scope of this study, it can be concluded that RVA remains an important etiology of neonatal diarrhea in calves of Brazilian cattle herds. |
