The aim of the work is to study the effect of tobacco smoke condensate (TSC) on biological characteristics of the agents of nonspecific pulmonary pathology: S. pneumoniae, H. influenzae, K. pneumoniae.
Materials and Methods. By means of the technique developed there have been carried out subculture inoculation on solid media with five successive TSC dilutions: from 10 mg/ml (the 1st dilution) to 0.001 mg/ml (the 5th one).
Results. There has been observed a stimulating effect of the 4th dilution (0.01 mg/ml) in the form of biochemical reaction increase, increased mucus production, the increase of the size and a number of colonies by 25—29% (S. рneumoniae, H. influenzae), p<0.05 and by 12% (K. pneumoniae). Thus, in some concentrations, TSC stimulates the growth of microbial cells.
