The group A rotaviruses are frequently associated with gastroenteritis in mammals and birds. The objective of this study was to detect the presence of rotavirus in feces of symptomatic and asymptomatic dogs for acute diarrhea. 32 samples of dog feces were collected. All the samples were submitted to viral RNA extraction followed by electrophoresis in poliacrylamide gels (PAGE), where only one case of rotavirus infection in one asymptomatic sample was found. The electrophoretic analysis showed 4:2:3:2 long profile, and the homology between human and dog rotaviruses was very high. This suggests a possible interspecies infection.
