Occurrence of Bovine Viral Diarrhea (BVDV) and Bovine Infectious Rhinotracheitis (IBR) Virus Infections in Buffaloes in Pernambuco state - Brazil

Persistent bovine viral diarrhea virus (BVDV) infection in cattle herds

Bovine viral diarrhea virus (BVDV) is a significant pathogen associated with gastrointestinal, respiratory, and reproductive diseases of cattle worldwide. It causes continuous economic losses to the cattle industry primarily due to decreased reproductive performance. The ability of virus to cross the placenta during early pregnancy can result in the birth of persistently infected (PI) calves. P...

Serological Surveillance of Infectious Bovine Rhinotracheitis virus, Bovine viral diarrhea virus and Bovine Parainfluenza-3 virus in Saudi Arabia

Comparison of Three Immunological Assays to Detect Infectious Bovine Rhinotracheitis (IBR) Antibodies in Buffaloes

The present study involved in analysis of 81 sera samples collected from Murrah (34), Surti (20) and non-descript buffaloes (27) with history of respiratory and reproductive disorders for IBR antibodies by indirect Enzyme linked immunosorbent assay (ELISA), Virus neutralization test (VNT) and Passive haemagglutination assay (PHA). The immunological assays viz., indirect ELISA, VNT and PHA revea...

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...

Epidemiology and eradication of infectious bovine rhinotracheitis/infectious pustular vulvovaginitis (IBR/IPV) virus in Finland

BACKGROUND Infectious bovine rhinotracheitis/infectious pustular vulvovaginitis (IBR/IPV) is a significant disease among domestic and wild cattle. The BHV-1 infection was first detected in Finland in 1970; presumably it was imported in 1968. The infection reappeared in the large-scale bulk-tank milk surveillances which started in 1990, and was eradicated in 1994. Our aim is to describe the epid...
