[Influence of cycloferon on the biological properties of bacterial intracellular pathogens].

The influence of cycloferon on some biological properties of pathogenic (Shigella spp., Salmonella spp., Francisella tularensis, Brucella spp.) and opportunistic (Escherichia coli, Staphylococcus spp.) microorganisms has been experimentally determined in vitro. As revealed in these experiments, the preparation used at concentrations under study considerably suppresses the antilysozyme and anticomplementary activity of Gram-negative intracellular parasites (shigellae, salmonellae, F. tularensis, Brucella). These data reveal one of the possible mechanisms of the action of cycloferon on intracellular parasites in acute and chronic bacterial infections.
