title: [The role of the persistence characteristics of microflora in the etiological diagnosis and determination of the sources of the infection of the urinary system organs in pyelonephritis in infants in the first year of life].
abstract: The microbiological status of 63 infants with pyelonephritis was determined. The importance of bacterial persistence factors for the identification of the infective agent and the detection of the source of infection of the urinary tracts was evaluated. The intestinal reservoir was shown to be the source of persistent microflora causing the formation of pyelonephritis, the change of the pathogenic species and the development of isolated bacteriuria at the end of the acute stage of pyelonephritis in children under 1 year of age.
