[Bacteriology and serology of pyelonephritis in children (author's transl)].
A short review is made on the bacterial pathogenicity factors related with urinary-tract invasion and renal damage in pyelonephritis. Microbiological findings obtained after a revision of 14,181 quantitative cultures carried our in the last nine years on children under 7 years old are discussed. "E. coli" is implicated in almost a half of positive cultures; "K pneumoniae" seems to be specially related with urinary infections of premature and newborn infants (20-30% of the bacterial positivities in both groups). "Proteus" and "Pseudomonas" have more etiological weight in older children. True hospital epidemics of urinary infections have been non observed. As serological test, the o-agglutination of homologous strain (technique of Karmierczac et al.) was used in order to determine the site of infection. A rather close correlation between positivity of serologic test and renal involvement is showed.
