Development and evaluation of recombinant gD protein based ELISA for sero-surveillance of BoHV-1 in India
Bovine herpes virus-1 (BoHV-1) is responsible for production losses through decreased milk yields, abortions, infertility, and trade restrictions in the bovine population. The disease is endemic in many countries including India. As the virus harbors a unique feature of latency animals once infected with the virus remain sero-positive for lifetime and can re-excrete the virus when exposed to stressful conditions. Hence, identification and culling of infected animals is only the means to minimize infection-associated losses. In this study, an economical indigenous assay for the detection of BoHV-1 specific antibodies was developed to cater to the huge bovine population of the country. The viral structural gD protein, expressed in the prokaryotic system was used for optimization of an indirect ELISA for bovines followed by statistical validation of the assay. The diagnostic sensitivity and specificity of the indirect ELISA were 82.9% and 91.3% respectively. Systematically collected serum samples representing organized, unorganized and breeding farms of India were tested with the indigenously developed assay for further validation.
期刊介绍:
Biologicals provides a modern and multidisciplinary international forum for news, debate, and original research on all aspects of biologicals used in human and veterinary medicine. The journal publishes original papers, reviews, and letters relevant to the development, production, quality control, and standardization of biological derived from both novel and established biotechnologies. Special issues are produced to reflect topics of particular international interest and concern.Three types of papers are welcome: original research reports, short papers, and review articles. The journal will also publish comments and letters to the editor, book reviews, meeting reports and information on regulatory issues.
