[Immunotherapy with autovaccines in urinary tract infections caused by gram-negative bacteria].

The efficiency of immunotherapy with autovaccines was determined in 162 patients with urinary infections produced by Gramnegative bacteria. In each case quantitative urocultures were performed, with examination of the urinary sediment, and blood samples taken before and after treatment with autovaccines in order to determine the agglutination and hemagglutination titer with autovaccines in order to determine the agglutination and hemagglutination titer with regard to the incriminated germs. The latter were identified by their enzymatic and serologic characters and their sensitivity to chemotherapeutical agents.

[Identification of some atypical (morpho-cultural and enzymatic) characteristics of E. coli strains isolated in different clinical and epidemiological conditions].

From among the 2813 E. coli strains isolated from various specimens (urine, feces, pharyngeal exudates, organs from fowls) in the course of two years, the authors selected and carried out a complex study on the strains exhibiting atypical features, considered to give rise to errors of diagnosis. Of the 2813 strains studied, 599 (21.
