title: Evaluation of antinfective activity of an association bifidobacterium/lactobacillus in mouse intestine.
abstract: The present research aimed at studying the action of an association of Bifidobacterium bifidum and Lactobacillus acidophilus, in controlling an experimental severe infection by Salmonella enteritidis administered in mouse per os. The behaviour of some parameters was undertaken, checking for the pH of intestinal content; the condition of the colonization in the intestinal wall by means of scanning electron microscopy and plates cultures; the presence of antibodies IgA in intestinal content; the index of mortality in the diversely treated animal's groups. The reported data show a string incidence of the administration of Bifidobacterium and Lactobacillus in increasing the animal's resistance against the lethal infection.
