Virom of intestinal canal and ulcerative colitis: new facets of interaction

Various lifestyle facts influence on microbial landscape of gut and change variety of microbiota with ulcerative colitis. New technologies of nucleotide sequencing, innovating statistics and bioinformatics grade into presentation about etiology and pathogenesis of some illness, for example ulcerative colitis. Current studies demonstrate that microbiome of gut acquaint with eukaryotic and prokaryotic viruses, which make virome of gut and be much part of microbial eco-system of intestinal tract. Number of bacteriophages and viruses escalete in the context of environmental stress so microbiome of the digestive tract disturbed. When we open specific microbiota, which associated with etiology of ulcerative colitis, we will create new treatment modality. Drive of this review is generalization of information about involvement with virome in ulcerative colitis becoming. For searching the literature were use systems PubMed and GoogleScholar with keywords: ulcerative colitis, gut virome, gut microbiome. Nowadays in the literature have limited but necessary information about this question. It requires accumulation scientifi c facts for integrated data.

Relationship Between the Populations of Streptococcus mutans in the Mouth and Feces of Conventional Sprague-Dawley Rats

The relationship between oral and fecal S mutans populations has been studied in rats fed high sucrose or glucose diet. All molar teeth were extracted either prior to or following oral challenge with strain 6715. In certain instances this procedure was supplemented with amputation of the incisors and disinfection of the remaining incisor surface area with iodine solution. The results suggest that in rats the colonization of S mutans on the teeth is required for its presence in the intestinal canal as well as the mouth. The significance of the observations has been discussed.
