【 摘 要 】

Picobirnavirus (PBV) is a small two-segmented double-stranded RNA (dsRNA) virus that has been identified in diarrheic feces of a large range of animal hosts, including humans. For this reason, PBV has been recognized as an opportunistic agent of gastrointestinal disease. Even under these circumstances, there is a lack of studies regarding this pathogen. Not outstanding, in Brazil, the single description of the PBV occurrence in pigs was provided in the 1980s. Hence, this study aimed to verify the PBV occurrence in Brazilian swine farms and to perform molecular characterization of the identified strains. High genetic variability was found in the analyzed sequences. Further studies comprehending the infection of swine by PBV in Brazilian herds should be performed to provide more accurate information on its epidemiology and to discuss the role of the virus in gastrointestinal diseases.
