ABSTRACT
Microflora inhabiting the gastrointestinal tract of humans is there in dynamic balance that can be disrupted, which in turn leads to diseases. One of the methods applied to restore this balance could be administration of probiotics. Seven Lactobacillus and two Bifidobacterium strains, isolated from the gastrointestinal tract and bio-yoghurts, were characterised. Two of them - L. acidophilus BS and L. salivarius AWH revealed good survival at low pH (100% and 90%, respectively) and in the presence of a high concentration of bile salts (89% and 74%, respectively). In addition, they revealed high antagonistic activity against Salmonella and coaggregated with this pathogen. The observed autoaggregation and hydrophobic properties of their cell wall suggest their ability to adhere to epithelial cells. The results proved L. acidophilus BS and L. salivarius AWH strains to be candidates for new probiotics, however, it needs further confirmation under in vivo experiments.
