SPECIAL FEATURES OF BACTERIAL FLORA, ASSOCIATED WITH MALIGNANT COLORECTAL TUMORS
The AIM of the study is to learn special features of microflora, associated with malignant tumors of colon and rectum. MATERIALS AND METHODS: 100 patients with various localizations of colorectal cancer were included in the study. During diagnostic flexible colonoscopy the biopsy of healthy mucosa and tumor tissue were performedfor microbiological study of the specimens. RESULTS: It was shown, that specimens from tumors were contaminated with gram- bacteria in 78 % of microbial isolates (potentially pathogenic flora). While normal mucosa bioptates had 72 % of microbial isolates of gram+ bacteria (obligate gut flora). Tumors of colon and rectum are associated with disbalance of microflora.: reducing of protective bacteria and increasing of potentially pathogenic flora.
