[The identification of nondiphtheritic bacteria of the genus Corynebacterium and the determination of their antibiotic sensitivity].

A total of 221 patients with nonspecific inflammatory processes were studied with a view to determine the occurrence and species composition of microorganisms of the genus Corynebacterium on the mucous membrane and in the secretions of their genitals. Different representatives of this genus were detected in 23.1 +/- 3.

[Fecal microflora in healthy young people].

The study of the intestinal microflora in 119 young adults was carried out. A high content of anaerobic representatives of the intestinal microflora (bifido- and lactobacteria) and extremely wide fluctuations in the number of E. coli (1-5 million to 700-800 million cells per g of feces) were shown.

[Enterobacterial sensitivity to colicins in the presence of enterochelin].

The correlation between the colicine resistance of the reference and isolated strains of enterobacteria and their capacity for the biosynthesis of enterocheline, as well as the influence of exogenous enterocheline on the colicine sensitivity of enterobacteria were studied. In the wild strains of enterobacteria sensitivity to colicines was shown to have no correlation with capacity for the accumulation of catechol-type sideriphores. In some cases exogenous enterocheline prevents the lethal effect of colicines on the cultures of microorganisms capable of the biosynthesis of enterocheline.
