摘要: Bovine rotavirus (BRV) has been detected in both dairy and beef cattle herds worldwide. Stool samples collected from calves the Gippsland region of Victoria, Australia were screened to determine presence BRV. A total 100 faecal with without diarrhoea across three farms during 2004 2005. Group BRV was 26% (22 diarrheic four asymptomatic calves). Genotyping analysis positive indicated that G6P[5] most prevalent genotype (38.5%) followed by G6P[5+11] (15.4%). G10P[11] G6+G10P[5] each at a rate 7.7%, G6+G10P[11] found single sample (3.8%). Seven (26.9%) could not be G and/or P typed. Thirty percent mixed infections, indicating individual co-infected more than one strain rotavirus. The strains exhibited high VP7 identity (>97% amino acid identity) B-60, G6 identified Victorian 1988. isolate closely related VP4 proteins) (B-11) also This study demonstrates is contributing pathogen diarrhoeal disease calves, sequence suggesting long-term conservation protein over 16-year period.
