Evidences of Serological Studies for The Presence of Infectious Bovine Rhinotracheitis IBR, In Albania

Abstract

Bovine herpesvirus 1 (BHV-1), the causative agent of infectious bovine rhinotracheitis (IBR), is considered to be the most common viral pathogen found in bovine. Virus enters through aerosol route or by direct contact with the nasal secretion in case of respiratory tract infection and by direct contact or by semen containing virus in case of genital infection. For the first time in Albania, this study was conducted to know the status of bovine herpesvirus-1 (BHV-1) antibodies in the bovines of the selected area of Albania. Antibody level was measured using a commercial indirect ELISA. A total of 263 collected serum samples from 7 areas of Albania were subjected to serum neutralization test for detection of BHV-1 antibodies by using of Indirect-ELISA kits. The chi-square test was used for comparison of results between regions and in this study p Values>0.01 was considered statistically no-significant at the 0.01 level. From these results we had an indication about the antibody prevalence of IBR infection respectively, 96% in Terpan-Berat, 52% in Fejza-Has, 50% in Kavajë, 33% in Rrëshen, 14.3% in Guras-Pogradec, 10% in Drenovë-Korçë and 0% in Fier. The prevalence was ranged from 10% to 96% among seropositive herds in this study. In conclusion, results of this study clearly established for the first time that BHV-1 is subclinical prevalent virus in bovine in Albania. Further studies are needed to prevent the spread of this viral infection in Albania.BHV-1,
