Abstract

Infectious Bovine Rhinotracheitis, caused by Bovine Herpesvirus-1 (BoHV-1) maintains latency in trigeminal nerve ganglia of bovine. The sero-positive bull infected with BoHV-1 secretes the virus through semen intermittently, when the immune system is compromised. Sera from bulls housed at different bull stations were analyzed using gE protein specific IDEXX Kit, which showed 78.69% positivity. Each batch of semen from sero-positive bull was investigated further for presence of virus in semen by Real Time-PCR technique for validation of presence of virus in the frozen semen doses using gB specific primers and probe, which showed 0.968 % semen batches positive. This study showed that despite high sero prevalence in bull, the semen excretes very negligible amount of the virus indicating the subtypes circulating in farms of West Bengal, India is assumed to be respiratory type.
