Enterotoxigenic Escherichio coli (ETEC) causes neonatal and post-weaning diarrhea in pigs. In order to determine the risk factors, rectal/fecal swabs and visceral organs obtained from pig farms in two regions of South Africa were analyzed microbiologically against risk variables. Seventy-two percent of young pigs were found to be positive for ETEC toxin genes; estB (38.9%), estB/STAP (25%), and estB/LT (13.9%) were dominant. Risk factors for ETEC-diarrhea in pigs include: leaving sick piglets in a pen with healthy piglets [odds ratio (OR) = 33.52; P 〈 0.0001]; water spillage in pen (OR = 42.87; P 〈 0.0001); hypothermic piglets (OR = 7.29; P 〈 0.0001); runt piglets in pen with healthy littermates (OR = 3.65; P 〈 0.0001); and prolonged use of antibiotics (OR = 3.05; P = 0.05). 展开更多
