From each depot/hatchery, 30 day-old chicks were randomly selected for their livers, spleens, kidneys, hearts, yolk sacs and intestines which were processed and cultured on appropriate bacterial media. Colonies that grew from the specimens were characterized based on their morphologies, staining characteristics, biochemical reactions and cultural characteristics. Gram positive isolates that were: short, plum shaped, rods, non-spore forming and non-capsulated were identified as Salmonella species. Motility test and biochemical tests on the Salmonella colonies identified those that were S. pullorum. Five percent of chicks being distributed in Akwa-Ibom State, Nigeria were infected with S. pullorum, the agent of, bacillary white diarrhea (which causes high mortality in chicks) and food poisoning in man.展开更多
