Detecting Salmonella From Egg Shell and Egg Nests

Abstract

A study was conducted to determine the prevalence of Salmonella spp. on quail eggshell, egg nests in Santhia upazila under Pabna district. A total number of 45 eggs and 25 egg nests were examined over a period of 2 month from two different farms. Salmonella contamination was recorded in 3 of 45 (6.6%) eggshell and 2(8%) in egg nests.. Isolated Salmonella was tested for resistance to eight different antimicrobial agents, using disc diffusion method. Among eight antimicrobial tested, 100% resistance were found to Ampicillin and Amoxicillin followed by Erythromycin (60-100%), Tetracycline (72-93%), Ciprofloxacin (22-66%), Colistin (27-66%), Enrofloxacin (42-54%) and Pefloxacin 23.07% across the study sites. Ciprofloxacin remained sensitive in 40.9%, Pefloxacin and Colistin appeared to be (61-72.22%) sensitive against Salmonella isolates at studied areas.
