Bovine herpesvirus (BoHV) type 1 is an important agricultural pathogen that infects cattle and other ruminants worldwide. Acute infection of the oro-respiratory tract leads to immune suppression and allows commensal bacteria to infect an otherwise healthy lower respiratory tract. This condition is known as the Bovine Respiratory Disease (BRD). BoHV-1 latently infects the host for life and perio...

Background and Aims: Bovine viral diarrhea virus (BVDV) is considered as worldwide and economically significant infection. The aim of this study was to estimate prevalence of persistent bovine viral diarrhea infection (PI) in industrial dairies of Tehran and Alborz province, Iran. Materials and Methods: In this cross-sectional study, 102371 blood samples were collected from bovine of industria...

Mycoplasma bovirhinis, a mycoplasmal species involved in bovine respiratory diseases, is also a commensal microorganism that inhabits the bovine respiratory and reproductive organs. We present the complete 948,039-bp genome sequence of M. bovirhinis strain HAZ141_2, which was isolated from bovine nasal discharge in Japan.

Bovine viral diarrhea viruses (BVDV) have been isolated alone or in combination with other viral and bacterial pathogens in animals diagnosed with bovine respiratory disease (BRD), a disease causing major economic loss to the feedlot industry. The objective of this experiment was to determine the effects of Mannheimia haemolytica challenge after short-term exposure (72 h) to bovine viral diarrh...

Undoubtedly, vaccination can be one of the promising approaches to control infectious diseases such as the COVID-19 pandemic. Inactivated viral vaccines have a history of "vaccine-induced enhanced disease", which may occur when neutralizing antibodies bind to viral antigens without blocking or clearing the infection. This can cause additional inflammation through the mechanisms described for ot...

The objective of this study was to determine the protein pattern and antigenic structure of BHV-1. Ten viral isolates from cows with clinical signs of respiratory infections were selected for this study and confirmed by SN test. All samples were cultured on cell cultures and purified by ultracentrifugation. Purified isolates were electerophorsed using SDS-PAGE method and immunoblotted. Vi...

waterborne epidemics of viral diseases have occurred and been reported over the years, and isolation of viruses from water of different sources has been made possible by different methods of concentration. it is now believed that bacterial parameters of water purity may not provide an adequate index as to the safety from a virological point of view. in this study eight samples from four main te...
