Given review is briefly summarizing published data on the history and current state such phenomenon as bacterial translocation. The basic patterns of saprophytic bacteria translocation, as well as theoretical and practical importance of further study of this phenomenon are described.
The dependence of quantitative and species composition of young rabbits microbocoenosis from feeding system was studied. It was found that in case of concentrate feeding system the number of bifidobacteria and yeast fungi increases. The influence of combined feeding system components on microflora composition of the gastrointestinal tract of young rabbits was studied. It was found that the introduction of a significant proportion of hay to rabbits’ diet leads to the decrease in the number of bifidobacteria and increase in the number of anaerobic bacilli, and in case of the diet based on grain the number of lactic acid bacteria increases and the number of yeast fungi decreases.
The paper presents the research results of prebiotics influence of different origin on the growth, enzymatic and antagonistic activity of representatives of normal cenosis of the cattle gastrointestinal tract. It was established that the lactulose prebiotic enhances growth activity of microorganisms from the gastrointestinal tract the most. Moreover, metabolites of aerobic bacilli had stimulated the most the antagonistic activity of lactic acid bacteria against S. typhimurium and E. coli.
The paper presents the results of studying of the dynamics and characteristics of the translocation of two probiotic strains of lactic acid bacteria in the blood and parenchymal organs of animals. The dependence of the bacterial translocation from the bacterial strain and from orally entered dose was established. It was shown that cultural-morphological and physiological-biochemical properties of all isolated from blood cultures of microorganisms have corresponded to the initial properties of bacterial strains introduced to the animals.
The paper depicts the results of the study of influence of internal environment of animals on preservation of initial biological properties of probiotic bacteria. The increased by 10–15 % antagonistic activity was observed in Bacillus subtilis 44-p strain after its translocation to the laboratory rabbits while for B. subtilis B3 the changes in the morphology of colonies (size and shape) were noticed. Nevertheless, the properties of the studied lactic acid bacteria after exposition to the internal environment of the macroorganism remain unchanged.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
