SEROPREVALENCE STUDY OF INFECTIOUS LARYNGOTRACHEITIS VIRUS ANTIBODY OF COMMERCIAL LAYER IN GAZIPUR DISTRICT OF BANGLADESH

Abstract

The research work was conducted to detect the prevalence of Infectious Laryngotracheitis (ILT) Virus-specific antibody in chickens from Gazipur district of Bangladesh. A total number of 232 sera of commercial layer were collected from 17 commercial layer farms. The studied commercial layers had not been previously vaccinated and were different ages. The indirect enzyme linked immunosorbent assay (iELISA) was performed to estimate the Infectious Laryngotracheitis (ILT) Virus-specific antibody. Out of 232 samples, 189(81.47%) samples were found to be positive. The result of this study indicate a high Infectious Laryngotracheitis (ILT) Virus activity in Gazipur district of Bangladesh hence there is an urgent need for the development of prevention and control policies against ILT in Bangladesh poultry farms and a _ national control programme for Infectious Laryngotracheitis Virus infection should be planned.
