[Serogrouping of Escherichia coli from urinary tract infections (author's transl)]
Abstract:
Serological grouping with 44 anti-O-sera was performed on 215 E. coli strains isolated from urine of patients with significant bacteriuria. 95 strains (44.2%) were typable, 34 strains (15.8%) proved to be rough strains, and 86 strains (40%) were untypbale. The O-groups 2, 6, 9 and 75 were found to be more frequent in patients with chronic pyelonephritis. Among pregnant women with asymptomatic bacteriuria a typical frequency was not observed.
