Rotaviruses A and C in dairy cattle in the state of Rio de Janeiro, Brazil.

ABSTRACT: Stool samples were collected from calves from nine family-based small dairy farms in the state of Rio de Janeiro, for detection and characterization of rotavirus (RV) species A, B, and C (RVA, RVB, and RVC, respectively) by reverse transcription polymerase chain reaction. Twenty-six samples (27.7%) were positive for at least one of the species: 22 (23.4%) samples were positive only for RVA, 3 (3.2%) were positive for RVC, and one sample (1.1%) had co-infection of RVA and RVC. RVB was not detected. Seven (21.9%; n = 32) animals with diarrhea and 19 (30.1% n = 62) asymptomatic animals were positive, with no significant difference in positivity (p = 0.3677). RV was detected in all properties studied, at rates between 14.3 and 80%, demonstrating the widespread circulation of RV in four of the
