[State of several parts of immune system in mice, infected by enterotoxigenic bacteria of Enterobacter genus].

Influence of thermolabile enterotoxin bacteria of Enterobacter genus on the immune system of mice was studied. Assessment of phagocytic functions of the immune system as well as antigen-presenting functions of macrophages during infection with enterotoxin-producing strains of bacteria from Enterobacter genus revealed pleiotropic effect of the toxin which is characterized by inhibition of antigen-presenting and processing functions of macrophages.

The study of the biological properties of 161 Salmonella strains isolated from the feces and faucial mucus of 121 young children revealed that at the initial period of salmonellosis the occurrence of Salmonella strains in these materials was the same. Salmonella strains sensitive to antibiotics, as well as group C salmonellae, were shown to be capable of causing hospital infections. Statistically significant results revealed that Salmonella strains isolated from the nasopharynx were more virulent than those isolated simultaneously from the feces of the same children.
