[Oral cavity microbiocenose in healthy teenagers and patients with chronic gastritis and gastroduodenitis].
Microbial association distinctive features and colonization degree of different oral cavity biotope were established in healthy teenagers and patients with chronic gastritis and gastroduodenitis. There were studied mucous membrane surfaces of cheek, tongue, content of gingival crevice, oral fluid and dental plaque of 24 healthy persons of the age 12-17 years and 29 patients of the same age with gastritis and gastroduodenitis. On the mucous membranes of the ill teenagers there were found Porphiromonas type bacteria, 20% more Staphylococcus, 90% less Peptostreptococcus, 30% less Lactobacillus, 20% less Veillonella and Stomatococcus. In saliva anaerobic Peptostreptococcus and facultative anaerobic Streptococcus (7 lg COE/ml); Porphiromonas, Veillonella, Peptococcus and Staphylococcus (6 lg COE/ml); Neisseria (5 lg COE/ml); Stomatococcus, Enterobacteriaceae and Bacillus (4.6 lg COE/ml); Lactobacillus and Candida (4 lg COE/ml) predominated. In patients with chronic pathology in all tested biotopes there was found the increase of the whole microbiota spectra (representatives of opportunistic pathogenic microfiora were detected more often) as well as the bacteria number if compared with healthy teenagers.
