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.
Description
Respiratory diseases of poultry result in great production losses for the industry
due to the severity of clinical signs. Infectious laryngotracheitis virus (ILTV) is
included among the respiratory pathogens that can infect chickens and cause
important economic losses. The disease can be present in two epizootic forms. The
severe form is characterized by high morbidity, and moderate to high mortality,
whereas the mild form commonly present now a days in the developed poultry
industries, is responsible for the presence of clinical signs including, tracheitis,
sinusitis, conjunctivitis, general depression, watery eyes, and low mortality.
Although recognized as the mild presentation of the disease it produces weight loss
and decreased egg production and has had a significant economic impact for the
industry in the past decade.
