The effect of probiotic strains (Enterococcus faecium EF55, E. faecium CCM7420, E. faecium CCM8558, E. durans ED26E/7, Lactobacillus fermentum CCM7421, L. plantarum 17L/1) on the production of superoxide anion (O2-) in peritoneal macrophages of Trichinella spiralis infected mice was examined. E. faecium EF55 and E. faecium CCM8558 strains increased the O2-production prior to parasitic infection,at the day7of application.A significant inhibition of the O2- production caused by T. spiralis infection on day 5 post infection (p.i.) was prevented by all examined strains. Lactobacilli stimulated metabolic activity of macrophages during intestinal and early muscular phase (from day 5 to 25 p.i.) of trichinellosis. Enterococci increased the O2- production in early intestinal phase (day 5 p.i.) and during the muscular phase of trichinellosis (days 25 and 32 p.i.). Respected increase in macrophage’s metabolic activity induced by probiotic treatment in the intestinal phase of trichinellosis augmented the host antiparasite defence (damage and killing of newborn larvae with reactive oxygen species from macrophages).
