To determine ability of lactobacilli strains indigenous for oral cavity of healthy persons to adhesion, autoaggregation, surface hydrophobicity, coaggregation and formation of biofilms.
Twenty-three anatagonistically active isolates of lactobacilli, including 5 strains of Lactobacillus plantarum, 6--L. rhamnosus, 4--L. paracasei, and 8--L. fermentum, were studied. Characteristics of lactobacilli associated with adhesion, autoaggregation, surface hydrophobicity, coaggregation, and formation of biofilms were determined.
Bacteria were characterized by high and intermediate level of adhesion, autoaggregation, surface hydrophobicity, expressed ability to form biofilms and different coaggregation activity relative to test-strains Staphylococcus aureus, Escherichia coli, Candida albicans, Pseudomonas aeruginosa, and Bacillus subtilis.
Studied characteristics of lactobacilli could be used for development of new probiotics aimed at stabilization of oral cavity normoflora.
