Abstract: | The adhesive properties of 215 cultures, including 215 Escherichia coli strains, 43 Klebsiella pneumoniae strains and 60 Pseudomonas aeruginosa strains isolated from the urine of 124 children with chronic obstructive pyelonephritis were studied in the direct hemagglutination test simultaneously with those of 30 E. coli strains and 20 K. pneumoniae strains isolated from the feces of 50 healthy children, as well as 60 P. aeruginosa strains isolated from children with parenteral infections of other localization. E. coli and K. pneumoniae strains isolated from the urine of children with chronic obstructive pyelonephritis were found to have D-mannose-resistant hemagglutinins (68% and 37.2%) and a combination of mannose-sensitive and mannose-resistant adhesins (44.6% and 13.3% respectively). P. aeruginosa strains isolated from the urine of urological patients in the postoperative period showed the presence of mannose-resistant hemagglutinins to a greater extent (76.6%) than those isolated from children with parenteral infections of other localization (45%). |
