title: [Serum resistance of Escherichia coli in chronic pyelonephritis. 1. Serum resistance in the human serum pool].
abstract: 123 patients of the kidney department of the Clinic for Inner Medicine of Rostock University suffering from chronic pyelonephritis were taken into microbiological observation for between one and four years. 170 E. coli strains were bred from 59 patients with significant bacteriuria in the course of the disease and their serum resistence was determined with pooled human serum using Taylor's method. 78.24% of the strains examined were serum-sensitive, 11.18% intermediate and 10.59% serum-resistent. All strains were O-, K- and H-typed. 57.06% were successfully O-typed and were distributed over 40 O-serogroups. 24.12% were not typable and 18.82% were rough colonies. 86.50% of the resistent and intermediate strains strains were O-typable, 13.50% could not be typed. The significance of E. coli antigens (O, K, H) and serum resistence for the maintenance of a chronic infection is discussed.
