Sporadic occurrence of hemorrhagic colitis associated with Escherichia coli O157:H7 in Newfoundland
During a 9-month period in 1984, 113 fecal samples obtained from 92 patients with diarrheal illness were cultured for Escherichia coli serotype O157:H7 to determine the occurrence of this agent in diarrheal illness in Newfoundland. E. coli O157:H7 was isolated in almost pure culture from 12 stool sp...
