Abstract: The study was aimed to identify causes and isolate Escherichia coli and Salmonella spp. from dead in shell embryos of chicken. The etiology and epidemiology of dead-in-shell embryos from two hatcheries (Government and Commercial) at Chittagong division were studied by using established bacteriological techniques alone with epidemiological study of farm biosecurity. Percentage of the condition in the Commercial hatchery and in Government hatchery was found to be 8.57% and 12.07%; respectively. The prevalence of isolated Escherichia coli and Salmonella spp from dead in shell embryos were 48% and 1%; respectively. But the prevalence of Escherichia coli was higher in Government farm (68%) compared to Commercial farm (28%). Salmonella spp was negative in the sample collected from Government farm but positive in Commercial hatchery (2%). Epidemiological investigation of both farms reveals that biosecurity and location of the farm might be a cause of higher embryonic death in Government farm in compare to commercial one. The study will help researcher to know the prevalence of Escherichia coli and Salmonella spp. from dead in shell embryos of chicken alone with epidemiology of farm biosecurity at Chittagong division.
