Abstrakt: Rotavirus (RV) infections represent a significant cause of enteritis and diarrhea in avian species and pose a major concern for the poultry industry. However, the prevalence of rotavirus infections among birds is poorly understood. Stool samples were collected from laying and broiler hens from commercial poultry farms in the states of Rio de Janeiro and Espírito Santo, Southwest region of Brazil, for detection of rotavirus species F and G (RVF and RVG, respectively) by reverse transcription polymerase chain reaction. RV was detected in 11.7% (38/325) of samples: 35 samples were positive for RVF and 3 for RVG. RVF was detected in 15 samples from Rio de Janeiro and 23 samples from Espírito Santo. RVG was detected in 3 samples from Espírito Santo. All the positive samples were from asymptomatic broiler chickens. The prevalence of RV infection in these flocks was high, especially considering that the birds had no apparent clinical disease. Silent circulation in the herds signifies the need for a continuous surveillance program to guide measures to control and prevent this viral infection. Continuous monitoring of pathogens is crucial to ensure greater productivity on poultry farms.
