Key result
A serological survey in Bangladesh revealed that 53.29% of 1,929 chicken sera tested positive for Avian metapneumovirus antibodies, with higher rates in older broiler breeder flocks.
Why the study?
Avian metapneumovirus causes significant economic losses and respiratory disease in poultry, but serologic evidence in Bangladesh had not been reported.
Cross-Sectional (n=1,929)
This first report of serologic evidence of AMPV in Bangladesh indicates that commercial poultry in the region is exposed to the virus.
Avian metapneumovirus (AMPV) is an important pathogen for chicken and turkey, responsible for acute upper respiratory tract infection and swollen head syndrome. The disease is highly contagious and causes significant economic losses in chicken and turkey flocks, particularly when associated with secondary infections. In the present study, we performed a serological survey in chicken sera collected from Bangladesh during the period 2014 to 2016. Of 1929, chicken sera examined by indirect enzyme-linked immunosorbent assay, 1,028 (53.29%) were positive. The incidence of AMPV antibodies was higher in broiler breeder flocks aged over 41 wk. The seropositive rate was higher in Gazipur and Mymensingh district and during rainy and winter seasons. This is the first report of serologic evidence of AMPV in Bangladesh. Our results indicate that commercial poultry in Bangladesh is exposed to AMPV.

Ali et al. (2019) conducted a cross-sectional in Avian metapneumovirus infection (n=1,929). Avian metapneumovirus (AMPV) exposure was evaluated on Seropositivity for AMPV antibodies by indirect ELISA. A serological survey in Bangladesh revealed that 53.29% of 1,929 chicken sera tested positive for Avian metapneumovirus antibodies, with higher rates in older broiler breeder flocks.
