title: [The microbiological diagnosis of pyelonephritis in children under the control of bacterial persistence factors].
abstract: The study of antilysozyme and anti-interferon activity in 474 urological strains of opportunistic bacteria isolated from the urine of pyelonephritis patients and in 302 strains isolated from the urine of healthy children was made. The occurrence and the average amount of bacterial persistence factors were found to be directly related to the isolation source of cultures. The determination of the antilysozyme and anti-interferon activity of urological strains made it possible to confirm the etiological importance of enterobacteria and Pseudomonas in the development of renal infections and to differentiate the causative agent of pyelonephritis from the concomitant microflora.
