Antibody titers to Escherichia coli heat-labile enterotoxin (LT) were measured in serum samples collected from mature cows, butcher pigs, mature sows and adult sheep, horses, dogs, cats, turkeys, and chickens. The frequency of LT antitoxin titers was greatest in sows (94%) and less in cows (38%). Titers were higher in swine than in cattle. There were no LT antitoxin titers in serums from sheep, horses, dogs, cats, turkeys, and chickens. It was concluded that LT-producing Escherichia coli are prevalent in the swine population, but much less so in cattle and the other species examined.
