Establishing presence of antibodies against bovine respiratory syncytial virus (BRSV), parainfluenza virus 3 (PI3) and bovine herpesvirus 1 (BHV 1) in blood serum of cattle using indirect immunoenzyme probe

Abstract

A total of 92 samples of bovine blood serum were examined for the presence of antibodies against the bovine respiratory syncytial virus using indirect immunoenzyme probe - iELISA. Specific antibodies against the bovine respiratory syncytial virus (BRSV) were established in 46, or 50% blood serum samples. Investigations of the 92 blood serum samples of cattle for the presence of antibodies against the parainfluenza virus 3 (PI 3), revealed their presence in 77, or 83.69% of the samples, and the presence of antibodies against the bovine herpesvirus 1 (BHV 1) was established in 19, or 20.65% of the samples
