| Abstract: | The article continues studies of the recently discovered bacteriolytic activity of interleukin-2. It was detected earlier that interleukin (IL-2) possesses greater substrate specificity in comparison with chicken egg lysozyme. IL-2 disrupted the cell wall of Escherichia coli but did not lyse lysozyme substrates such as the cell walls of Micrococcus luteus and Bacillus subtilis. In the present study it is demonstrated for the first time that both IL-2 and chicken egg lysozyme are capable of lysing Lactobacillus plantarum. The effects of IL-2 and chicken egg lysozyme on Lactobacillus plantarum are compared with those on Escherichia coli. The dependences of the rate of lysis on the concentration of bacteriolytic factors and pH are studied. |
