Abstract:
The substantial influence of presence of the double converting prophages of the serological group F on the decrease of intensity of human leukocytes stimulation with lysogenic cells of S. aureus was determined. The end values of chemiluminescence in the six experimental systems containing lysogenic bacteria were only from 15.4 to 37.2% of the value in the control sample. The end values of the intercellular killing of the two lysogenic variants were twofold lower than in controls. Third of the investigated variants was completely resistant to intracellular killing in the applied system, and revealed 27% of growth stimulation.
