Detection of Antibodies against Bovine Immunodeficiency-Like Virus in Daily Cattle in Hokkaido.

Detection of bovine immunodeficiency virus antibodies in cattle by western blot assay with recombinant gag protein.

A western blot assay using purified recombinant bovine immunodeficiency virus gag protein has been developed for detection of bovine immunodeficiency virus antibodies in bovine serum samples. The test was standardized with known bovine immunodeficiency virus positive and negative bovine serum samples and the monoclonal antibody to gag protein. Both naturally and experimentally infected cattle s...

Detection of Antibodies Against Bovine Leukemia Virus

A modified syncytium-induction inhibition test which is more sensitive than the immunodiffusion test, was developed using rabbit complement. In this test, fetal lamb kidney cells continuously infected with bovine leukemia virus were used as effector cells, and the CC81 cat cells transformed with murine sarcoma virus, were used as indicator cells. The syncytiuminduction inhibition effect of anti...

The first study of bovine immunodeficiency virus (BIV) and bovine viral diarrhea virus (BVDV) co- infection in industrial herds of cattle in two provinces of Iran

BIV is a well-known bovine immunosup-pressive cause, but its pathogenesis has not been well characterized. It seems that it is possible that cofactors such as co- infection with other bovine viral pathogens may play a role in enhancing the pathogenesis of BIV infection; BVDV also has immunosuppressive effects. OBJECTIVE: The aim of this study was determination of possible correlation between BI...

Detection of antibody against infectious bovine rhinotracheitis glycoprotein gE in aborted cattle in Mashhad, Iran

Infectious Bovine Rhinotracheitis is a highly contagious disease caused by the bovine herpes virus-1 (BoHV-1), resulting in significant losses to livestock around the world. BoHV-1 is a major pathogen of cattle, primarily associated with respiratory/genital tract infections and abortion. In the present study, we determined the presence of antibodies in 120 serum samples of cattle with the histo...
