Seroprevalence of Borna disease virus in domestic animals in Xinjiang, China.

The study observes the presence of a disease known as Borna disease virus (BDV) in domestic animals in Xinjiang, China, with findings indicating the prevalence of the disease in horses and sheep within the surveyed district.

Introduction to the Study

• The researchers in this study sought to investigate the rate of infection by the Borna disease virus (BDV) among different group of domestic animals and wild rodents in Xinjiang, China.
• The animals under study were horses, sheep and cattle with each group having a count of 20 individuals, and a larger group of 165 wild rodents spanning across 18 different species.

Method and Results

• The method utilized to identify the presence of the virus in these animals was the use of an enzyme-linked immunosorbent assay (ELISA) and an immunoblot. These are both standard scientific methods used extensively in immunology to detect the presence of an antibody in a blood sample.
• The outcome showed the presence of antibodies against two variants of BDV, namely BDV-p24 and BDV-p40, in both horses (with a seroprevalence rate of 20%) and sheep (seroprevalence rate of 25%). These antibodies are produced by an organism’s immune system when the organism is infected with BDV.
• In contrast, there was no discernible positive reaction detected either in the bovine group or the rodents. This means that the samples from these animals did not yield any evidence of BDV infection.

Conclusion

• The findings suggest that the Borna disease virus is prevalent among horses and sheep in Xinjiang district, based on the detection of BDV-p24 and BDV-p40 antibodies in their blood samples.
• However, the virus was not detected in cattle or wild rodents in the area, suggesting that these species are not carriers or prone to infection by BDV under the conditions of this study.
