Gastric Microbiota and Morphological Changes of the Gastroduodenal Tract Associated with Helicobacter Pylori Infection

© 2016, Springer Science+Business Media New York.Investigation of the microbiota at morphological changes of a gastrointestinal tract. One hundred four patients were examined by cytologic, bacteriological methods, and mass-spectrometry techniques. Studying of the microbial association of stomach has demonstrated the mixed microflora presented by Helicobacter pylori, cocci, fungi Candida, rods, and protozoa. Bacteria of the following species were found: Actinomyces, Arthrobacter, Bacillus, Corynebacterium, Lactobacillus, Neisseria, Pseudomonas, Rothia, Staphylococcus, Streptococcus, and Streptomyces. The microbial flora of esophageal samples was less various (opportunistic bacteria Neisseria, Gemella, and Rothia mucilaginosa were revealed). In group of Helicobacter-positive patients, bacteria were found in fungi Candida, Colletotrichum, and bacterias Thauera and Mycoplasma, while in H.pylori-negative patients, samples have more different species. Intensity of morphological changes (the atrophy, the intestinal metaplasia, and the dysplasia) correlated with a frequency of detection of H. pylori and eukaryotic microbiota (fungi Candida and protozoa)

Effect of exogenous and endogenous nitric oxide on biofilm formation by Lactobacillus plantarum

Biofilms are a widespread form of occurrence of microorganisms in nature, and understanding the mechanism of regulation of their formation is of unquestionable practical significance for medicine and biotechnology. In the present work, the effect of nitric oxide (NO) on biofilm formation by Lactobacillus plantarum was investigated and the micromolar concentrations of exogenous NO were shown to have a negative effect on this process due to its toxic effect on the cells. However, the decrease in the level of endogenous NO in bacteria in the presence of a nitric oxide scavenger 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (cPTIO) impaired the characteristics of the forming biofilms, as was evident from the decrease in their size. © 2013 Pleiades Publishing, Ltd
