study on duration of maternal antibodies in calves against bovine herpes virus (bhv-1)

Study on duration of maternal antibodies in calves against Bovine Herpes virus (BHV-1)

In order to estimate the mean of maternal antibody in calves against BHV-1 (Bovine Herpes virus type 1), this study was carried out in a population of calves from non-vaccinated dairy cattle at 2 livestock in Qazvin province. One hundred thirteen sera out of 512 were collected from 1-4 months unvaccinated calves. We used Blocking –Percentage of maternal antibodies against BHV-1, which obtained ...

Dot-Blot Enzyme Immunoassay for the Detection of Bovine Herpes Virus-1(BHV-1) Antibodies

Various detection methods have been developed for serological monitoring BHV1, an alphaherpesvirus and the cause of the respiratory disease, abortion, conjectivitis and other clinical forms of disease complex in cattle, in different laboratories throughout the world. The objective of this study was to develop and evaluate dot-blot enzyme immunoassay as a proper and inexpensive method for detect...

Serological study of bovine herpes virus type 1 in dairy herds of Hamedan province, Iran

A cross-sectional study with a random cluster sampling design was carried out to estimate the seroprevalence of bovine herpesvirus type 1 (BHV-1) in non-vaccinated dairy herds in Hamedan province, west of Iran. Simple random sampling was used for selection of cattle in each herd. Informative data about each herd and selected animals were recorded by the farm manager in a provided questionnaire....

Seroepidemological Survey for Antibodies against Infectious Bovine Rhinotracheitis and Bovine Herpes 4 Viruses among Cattle in Different Provinces of Iran.

Evaluation of indirect Enzyme Linked Immuno Sorbent Assay and Virus Neutralization Test in the diagnosis of Bovine Herpes Virus – 1 (BHV-1) antibodies in cattle

To ascertain the prevalence of BHV-1 antibodies among cattle population, Virus neutralization test (VNT) and indirect Enzyme linked immunosorbent assay (ELISA) were employed for the detection of BHV-1 antibodies. Evaluation of these two serological tests was made to find out the rapid, economic and sensitive diagnostic test for detection of BHV-1 infection. A total of 255 serum samples were col...

Bovine Herpes Virus 1 (BHV-1) and Herpes Simplex Virus Type 1 (HSV-1) Promote Survival of Latently Infected Sensory Neurons, in Part by Inhibiting Apoptosis

α-Herpesvirinae subfamily members, including herpes simplex virus type 1 (HSV-1) and bovine herpes virus 1 (BHV-1), initiate infection in mucosal surfaces. BHV-1 and HSV-1 enter sensory neurons by cell-cell spread where a burst of viral gene expression occurs. When compared to non-neuronal cells, viral gene expression is quickly extinguished in sensory neurons resulting in neuronal survival and...
