[The reciprocal effect of the causative agents in a mixed infection in burn injury].

In vitro experiments on the joint cultivation of Pseudomonas aeruginosa, Escherichia coli, staphylococci and in vivo experiments carried out on mice with the experimental mixed infection of a burn injury revealed the pronounced antagonistic action of P. aeruginosa with respect to staphylococci and E. coli. Under the same conditions, in the joint cultivation of P. aeruginosa and fungi of the genus Candida and in the mixed infection of a burn wound caused by the same microorganisms the mutual stimulation of multiplication and a considerable aggravation of the clinical course of a burn wound were observed. The mutual influence of associates in the mixed infection of a burn injury is manifested by an increase in the number of an antibiotic-resistance microorganisms in their populations and, so far as the macroorganism is concerned, in the aggravation of the course of the infectious process and the formation of the pronounced state of immunodeficiency.
