The influence of Lactobacillus reuteri on the systemic immunity response in relationship to the bacterial pathogen E. coli in the digestive tract of piglets was studied. In two model experiments, 18 pigs in two groups, experimental (E) and control (C) were used. For 49 days, 10 animals in group E were given 3 ml of L. reuteri orally every 5 days. Each animal received 3 ml E. coli. Blood was collected from eyes, through the venous circulation, at 49, 54 and 59 days of age. Phagocytic activity of neutrophils (FA Ne) and leukocytes (F Lc), the phagocytic activity index of neutrophiles (IFA Ne) and leukocytes (IFA Lc), reduction of tetrazolium salt (INT test) and concentration of total immunoglobuline (TIg) were determined. 24 hours after application of E. coli in group C, the first clinical changes, such as increased temperature and, in one case, death, appeared. In group E no death was recorded. Obtained values were highest in group E on day 59. Body weights of piglets in the E group from Day 54 were higher to the end of the experiment
