title: [Interference of the intestinal ecosystem of mice in the oral administration of lyophilized live bacteria].
abstract: Oral vaccines mode by living or killed bacteria are commonly used to restore normal intestinal flora; it's not well know, however, which bacteria play the leading part in this ecosystem. In the present paper Authors have intended to compare the effectiveness of an oral vaccine, made by Bifidobacterium bifidus and Lactobacillus acidofilus, with another of similar use, made by Enterococci, to increase the mouse resistance to lethal Salmonella enteritidis infections. According to collected microbiological data and M.E.S. photos, the association Bifidob./Lactobac. is more effective than Enterococci to enhance resistance to the experimental infection.
