Electron Microscopy study of interaction of lactic acid bacteria with pathogenic microorganisms

With the use of scanning electron microscopy, we have demonstrated that bioactive substances produced by Lactobacillus plantarum and Lactobacillus acidofilus exert a bacteriostatic effect on the populations of pathogenic and opportunistic pathogenic bacteria Listeria innocua, Salmonella enteritidis, Proteus vulgaris, Escherichia coli, and Klebsiella pneumoniae, which reveals itself by transformation of a population into heteromorphism with the various manifestations of L-transformation.
