Comparative Analysis of Escherichia Coli Strain Plasmid DNA Profile, Isolated From Normal and Malignant Intestinal Epithelium of the Patients with Colorectal Cancer.

摘要

ABSTRACT Optionally cultured aerobic bacteria were isolated from the biopsy materials from the colorectal cancer patients (CCP). The species belonging was determined using MALDI-TOF mass spectrometry. Escherichia coli bacteria were the main representatives of patient microflora. 16 strains of E. coli were selected from normal and oncologically transformed epithelium to characterize a set of their plasmids. An antagonistic activity against E. coli K12 was found only in 3% of the strains. There i.
