The invention relates to a use of Lactobacillus reuteri DAN080 strain with deposit number DSM 15693 as an active component for manufacturing a dermaceutic effective in skin infections in vertebrate, in particular human being, other mammal or bird, and for manufacturing a medical device in the form of a dressing or hygienic materials for use in a wound care and personal hygiene - respectively, to avoid skin infections in vertebrate, in particular human being, other mammal or bird, as well as for manufacturing a medical device in the form of plastic protector sheet and fire-blankets intended for rescue units, including fire-brigades, specifically for patients with extensive skin bums and for victims of communication accidents with serious body surface injuries, to avoid skin infections in vertebrate, in particular human being, other mammal or bird.The Lactobacillus reuteri DAN080 strain with deposit number DSM 15693 is used in form of the L. reuteri DAN080 strain culture, partially inactivated L. reuteri DAN080 strain culture； liquid supernatant of L. reuteri DAN080 strain culture, concentrated supernatant of L. reuteri DAN080 strain culture and dried supernatant of L. reuteri DAN080 strain culture for prophylaxis and treatment of medical conditions developing as a result of infections caused by bacteria, fungi, and other pathogens of the body surface in vertebrate, and alternatively in form selected from the group comprising the whole L. reuteri DAN080 strain culture； liquid, concentrated and dried supernatants obtained from L. reuteri DAN080 strain cultures and from mixed bacterial cultures containing L. reuteri DAN080 strain and liquid, concentrated and dried supernatants obtained from the cultures of prokaryotic and eukaryotic recombinants, and the whole cultures of prokaryotic and eukaryotic recombinants, in which and/or from which genes are utilized, which genes provide specific modulatory, inhibitory, and homeostatic activity with respect to H. pylori and other
