Probiotic potency of Aerococcus viridans on biomodel of white mice organism
Journal Title: Бюлетень "Ветеринарна біотехнологія" - Year 2018, Vol 32, Issue
Abstract
Introduction. Aerococcus viridans is a ubiquitous resident representative of the normal microbiocenosis of open cavities in animals and humans, an indicator of the health status of the macroorganism in relation to the quantitative and qualitative composition of the microbial community, primarily the intestinal tube. Aerococci belong to the active products of hydrogen peroxide and, possessing pronounced probiotic potencies, are able to enter into a competitive antagonistic relationship with the transient microflora for the ecological niche in the macroorganism, in this case, the surface of the mucosa of open cavities. The goal of the work was to study of adhesive properties and colonizing ability of the probiotic culture of Aerococcus viridans, as the most important aspects of the probiotic potencies of the peroxide-producing prokaryote. Results of research and discussion. In the homogenates of all examined parts of the intestine, the aerococci were contained in a sufficiently large amount, which indirectly indicates a strong association of the antagonists with the mucosa of the gastrointestinal tract. As a result of the experimental work, it was established that aerococci-antagonists presented in all parts of the digestive tract. The frequency of their detection was correlative depending on the content of antagonists in this or that part of the intestine. In the largest number of aerococci were recorded in the large intestine. Taking into account that the probiotic prokaryotes of Aerococcus viridans are representatives of the indigenous microflora, they populate all open cavities of the macroorganism, with an average titer of 4.1–8.8 lg CFU/сm3. Conclusions and perspectives of further research. Thus, it can be argued that aerococci have the ability to attach and colonize the surface of the intestinal mucosa, occupying their ecological niches and thus, due to competitive antagonism over the biotope, interfere with the adhesion of tracer pathogenic and opportunistic enterobacterias, which generally characterizes aerococci as microbionts possessing pronounced probiotic potencies.
