ABSTRACT
The aim of the present work was to study the fact of the possible influence of live Lactobacilli on the nonspecific resistance of the organism to infection invasion: intensification of the bactericidal and phagocytary activity of forming units of the immune protection. The study was carried out in a human groups to identical nutritional regims and motor activity. The groups received 50 g BIOSTIM, with 0.9% pectin, containing live Lactobacilli, strain LBB.H.4, from the LBB collection of LB BULGARICUM—CRDP. The selected parameters are sufficiently adequate and informative for assessing the action of the fermented milk products.
