Treść
INTRODUCTION. Most probiotic strains occur among lactic acid bacteria, particularly Lactobacillus, Bifidobacterium and Enterococcus. These bacteria are part of the normal intestinal microflora of animals and can be used as probiotics. Their biological activity is closely linked with the ability to produce bioactive metabolites. AIM. The aim of this study was to isolate lactic acid bacteria strains from pigs showing antagonist activity of pathogenic E. coli enterotoxic. MATERIALS AND METHODS. Screened bacterial isolates were obtained from the upper and lower gastrointestinal tract of healthy pigs. Determined their activity against pathogenic strains of E. coli indicator. Screening was performed by point by measuring the diameter of the clearing zones around the isolates deposited on the agar medium inoculated with bacteria indicator. RESULTS. We examined 178 isolates collected from the upper and lower gastrointestinal tract of pigs. Shown forming ability LAB normal gastrointestinal microflora of pigs to the antagonist effects on E. coli. Antagonistic activity against more than one strain of the indicator showed 53 isolates from pig manure and 17 isolates from swabs of the mouth. CONCLUSIONS. In the gastrointestinal tract of pigs lactic acid bacteria have been identified that can be used as an effective probiotic for pigs.
