Sawkat Anwer, Ahasanul HoqueAbstractBangladesh experiences some of the highest malnutrition rates in the world, and efforts are being made to increase food security and overall health status. One of the largest constrains on increasing food security is endemic diseases among livestock and poultry populations. Newcastle Disease (ND) is one of these viral endemic diseases reducing food security. However, the sero- and viro-prevalence of ND has not been thoroughly studied in rural poultry in Bangladesh. Knowledge of farm management practices and their effect on ND sero and viro-prevalence is needed before interventions can occur, and efforts to improve the endemic state of ND cannot begin without a baseline study. This cross-sectional study randomly sampled 129 rural households with 245 chickens for the sero-prevalence and active infection rate of rural chickens in two selected upazilas (sub-districts) of the Chittagong district. ELISA was used for the detection of sero-prevalence, and cloacal samples were analyzed for ND presence using one-step RT-PCR. The aims of this study were to describe farmer demography, determine the ND sero-prevalence at the household and individual chicken level, estimate the proportionate ND prevalence at the individual chicken level, determine potential risk factors for ND ...
