ABSTRACT
Ten faecal samples of bovine rotavirus from calves less than 30 days old from an outbreak of diarrhea in Hidrolândia, Goiás, Brazil were submitted to serological and molecular characterization, using enzyme immonuassay for subgrouping and serotyping, PAGE for determination of electropherotypes and PCR for genome typing. Nine samples belonged to group A/subgroup I rotavirus one samples was group A / soubgroup non-I/non-II. Four samples were characterized as G10P[11] (B223-like), four samples showed a mixture of two rotavirus strains (G6G10 and P[5]P[11]), one sample was characterized as G6P[11] and one sample was characterized only by G serotyping/genotyping, and did not react with any primer used. Two electropherotypes were detected and both were present in the same animal. This study demonstrates that two different electropherotypes and/or serotypes of bovine rotavirus can circulate in the same outbreak.
