[Distribution of the O-group of "E coli" isolated in urinary tract infections (author's transl)].
The distribution of the O-groups of E. coli isolated in urinary tract infections by several italian and foreing Authors are reviewed and compared with the distribution obtained by us in the O-grouping of 300 strains isolated during 1976 in hospital and in surgery. Our results are similar to those of above-mentioned Authors. In fact O6, O75 and O2 groups are the most frequent; besides for the first time a considerable number of "enteritogenic" groups has been isolated and the most frequent of them was the O126. According to the results, the theory of specific pathogenicity could be supported by the high frequency of the O6, O75 and O2 groups; the presence of other groups could justify the theory of prevalence.
