title: [Virulence factors in strains of Escherichia coli isolated in urinary tract infections].
abstract: In 21 strains of E. coli isolated from patients with cystitis and asymptomatic bacteriuria the authors assessed the group, mannososensitive and mannoresistant agglutination of human, bovine, chick, guinea pig, sheep and pig erythrocytes, the production of haemolysis, colicins, aerobactin, the capacity of strains to induce oedema on mouse paws, the lethal effect in mice, the resistance to tetracycline, streptomycin, chloramphenicol, kanamycin, ampicillin and sulfamethoxidine, the transmission of resistance and sensitivity of strains to the action of fresh human serum. In ten strains the authors recorded also the production of haemolysin and the lethality for mice, in four strains the production of colicin V. production of aerobactin and serum resistance. In three strains the aerobactin production was recorded concurrently with the haemolysin production. In none of the samples P. fimbriae were found.
