AIM: To determine characteristics of microbial associations and degree of oral cavity colonization by different biotopes in healthy adolescents and patients with chronic gastroduodenitis.
MATERIALS AND METHODS: Saliva, dental deposit, content of tooth-gingival cavity and material from buccal and lingual mucous surfaces of 24 healthy adolescents and 29 patients of the same age with gastroduodenitis were used for bacteriological analysis. Inoculation were made on the following growth media: yolk-salt agar, Endo, Saburo, MRS as well as on Columbia and Saedler blood agars.
RESULTS: It was shown that rate of isolation of peptostreptococci from oral cavity of patients was 90% lower compared with controls; rate of isolation of lactobacilli, Veillonella, and stomatococci was 30% lower, whereas hemolytic Porphyromonas, staphylococci and streptococci were isolated 20% more frequently. Concentration of peptostreptococci and streptococci was 7.0 lg CFU/ml, whereas concentration of Porphyromonas, Veillonella, peptococci and staphylococci was 6.0 lg CFU/ml, Neisseria--5.0 lg CFU/ml, stomatococci, bacilli and Candida fungi --4.5 lg CFU/ml. Decrease of concentration of lactobacilli to 4.0 lg CFU/ml was noted.
CONCLUSION: Compared with healthy group of children, widened spectrum of microorganisms in all studied biotopes of oral cavity was observed in patients with chronic gastroduodenitis; species belonging to pathogenic microflora were detected in patients more frequently and in more quantities.
