[Microbiological aspects of zirconia orthopedic structures].

The article gives a detailed analysis of oral cavity microbiological aspects of 23 patients before and after prosthetic treatment with zirconia structures. Microbiocenoses of oral cavity in patients with defects of the dentition can be described as disbiotic. It was found that the incidence of lactobacilli and bifidobacteria was increased and frequency of occurrence of pathogens, including Staphylococcus aureus, was decreased under the influence of temporary plastic prosthesis as an intermediate step prosthetics.

[Microbiocenosis of major biotopes of the oral cavity in patients with tongue carcinoma during complex treatment].

The composition of the microflora in three biotopes of the oral cavity was examined in 36 patients with tongue carcinoma before chemotherapy, one - two weeks after two courses of chemotherapy and before gemiglosseklomiya. The oral dysbiosis was revealed in patients before antitumor therapy. The opportunistic and pathogenic bacteria in concentration more than 4 lg CFU/cm² were dominant in microbiocenosis of oral cavity.

[Antagonism of lactobacilli, oral streptococci and staphylococci].

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.
