Genomic Diversity among Rotaviruses isolated from Diarrhoeic Buffalo calves

Eighty three bovine samples were collected over a period of six month duration from October 2008 to March 2009 between age group of 0-1 year with diarrhoea from veterinary polyclinics, dairy animal farms. Out of eighty three faecal samples screened for rotavirus by RNA- PAGE, 6 (7.22%) were found positive. The electrophoretic migration of all the field isolates was 4:2:3:2 which is typical of group ‘A’ rotavirus. Migration of segments 10 th and 11 th was faster indicating “long” electropherotype and subgroup I specificity of the virus. In this study, a total of 4 different electropherotypes were identified among bovine rotaviruses.
