Epidemiological investigation on Bovine alphaherpesvirus 1 and bovine viral diarrhea virus in cattle and camels in southern Egypt.

Abstract

In this study, the ELISA procedure was used to detect antibodies against bovine viral diarrhea (BVDV) and infectious bovine rhinotracheitis (IBRV) viruses. The BVDV serological survey in Aswan province in southern Egypt was carried out on 184 unvaccinated cattle and camels. The overall seroprevalence was 18.48% (34/184), but in cattle was 34.78% (32/92) and 2.18% (2/92) in camels. The serological survey was conducted on infectious bovine rhinotracheitis virus (IBRV) antibodies was conducted on 460 unvaccinated cattle from three different provinces (Qena, Luxor, and Aswan). The overall seroprevalence was 60.00% (276/460). The infection rate in Aswan was higher (83.70%) than Qena and Luxor, 53.63% and 45.65%, respectively. Epidemiological status was established to clarify the influence of location in Qena, Luxor and Aswan for bovine viral diarrhea and infectious bovine rhinotracheitis and the effect of management systems in infection rate for cattle. The high predominance of antibodies in cattle may be the principal factor to limit the cattle industry in Egypt. This study aims to investigate the seroprevalence rate of Bovine alphaherpesvirus 1 and bovine viral diarrhea in cattle and camel in southern Egypt.
