abstract：:When inoculated orally, Escherichia coli strain 1056 caused acute enteritis in 7 of 22 weanling hamsters. E. coli strain 1056 was isolated from the ileum of a hamster with proliferative ileitis. It was lactose negative, nonmotile, and anaerogenic. By electron microscopy and indirect fluorescent-antibody techniques, E....
