Abstract:
From the oral cavity of healthy young people aged 18-22 years there were isolated 26 strains of lactobacilli, 28 streptococci, including the pathogenic and opportunistic strains, and 32 strains of staphylococci, 10 of which were methicillin-resistant S.aureus. Oral lactobacilli possessed by a high probiotic potential, showing high antagonism to methicillin-resistant staphylococci, pathogenic and opportunistic streptococci and enterococci. Oral lactobacilli showed medium and high adhesive activity that determines their high adaptive capacity. Staphylococci and streptococci in 90.3% of cases have not an antagonistic effect on lactobacilli. Isolated lactobacilli can be used as probiotic strains for oral administration.

Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
