The faecal carriage rates of different species of were assessed in studies with 220 faecal isolates from 219 individuals of whom approximately one-third were well and the remainder had gastro-enteritis. As a result of the development of new media that allowed replacement of the phenylalanine deaminase test with the tryptophan deaminase test and made it possible to combine tests for indole and urease production and for hydrogen sulphide and ornithine decarboxylase formation in two single-tube tests, all strains were speciated with speed, economy and accuracy. Most (96%) isolates were either (62%) or (34%). The significance of these findings in relation to urinary tract infection is discussed. was found in only one (0·45%) faecal specimen and this rarity of carriage in faeces is believed to be the main reason for its rare association with urinary tract infections. The frequent association of , in the absence of other enteropathogenic bacteria, with severe gastroenteritis was noted with interest.
