[Characteristics of microbial associations represented by the Enterobacteriaceae family isolated from the feces of healthy children and children with salmonellosis].

Associations formed by microorganisms of the family Enterobacteriaceae in feces have been studied using the principles of ecological investigation. The study has revealed that the associations isolated from children with salmonellosis sharply differ from those isolated from healthy children in the number of species and in the variety of their combinations, as well as in changes in the proportion of different species, observed in multiple investigations.

[Strains of the family Enterobacteriaceae isolated from chronic bacterial carriers of Salmonella typhi and Salmonella schottmuelleri and from healthy persons].

Fecal samples obtained from 51 chronic carriers of S. typhi and S. schottmuelleri and from 35 healthy persons were studied.

[Transfer of kanamycin resistance among familial strains of Enterobacteriaceae isolated from a chronic bacterial carrier of Salmonella schottmuelleri].

Escherichia coli, Enterobacter aerogenes and S. schottmuelleri were isolated from the large intestine of a bacteriocarrier. E.

[Interrelation between the presence in enterobacteria of distinct biological properties and their capacity to colonize the small intestine in the early stage of the development of postradiation dysbacteriosis].

An increase in the percentage of antibiotic resistant and hemolysin-producing enterobacteria occurring in the process of the development of postradiation intestinal dysbacteriosis was due to a sharp increase in the number of such bacteria among the representatives of the genera inhabiting the large intestine of mice (E. coli, E. aerogenes, E.
