title: [Escherichia coli with the K1 antigen isolated in pyelonephritis in children].
abstract: The identification of K antigens in 113 E. coli strains isolated from the urine of 62 pyelonephritis patients was carried out. 84 strains were found to possess K antigens. The presence of K antigens was revealed in strains both in the S-form (67 cultures) and in the R-form (17 cultures). Among the strains with K antigens the presence of K1 antigen was revealed in 41.7 +/- 6.5% of cases. K1 antigen was found in combination with eight groups of O antigens (01, 02, 04, 017, 018, 050, 077, 0141) and with R antigens. The above-mentioned E. coli strains were isolated from 16 patients; of these, 3 patients had chronic pyelonephritis.
