title: [Significance of the ability of E. coli to alter capillary permeability for the reproduction of pyelonephritis in mice].
abstract: Experiments in a number of biological models showed that the cultures of E. coli isolated from the urine of children with pyelonephritis had a varied spectrum of pathogenic properties. Histologically confirmed pyelonephritis induced by intravenous infection in CBA mice, treated with 5% glucose by the method of Montgomerie et al., correlated with the bacterial adhesiveness to the epithelium and the interference with capillary permeability, registered in experiments on the pulmonary model with Evans blue used for control. The criterion for the development of pyelonephritis in mice, which was based, in the opinion of Mintogemerie et al., on the positive results, indicating the presence of the infecting agent in the culture obtained by inoculation with the samples of urine and kidney tissue, was found to be insufficient, as only 28 out of 45 cultures of E. coli isolated from the kidneys coincided with histologically confirmed cases of pyelonephritis.
