- Abstract
- Strains of Lactobacillus spp., isolated from
sourdough and olive brines (seven strains), and three
human isolates were screened for their antagonistic activity
in coculture against the ureolytic pathogen Yersinia enterocolitica.
A general reduction in the pathogen
population was observed after 6 h when each Lactobacillus
strain was cocultured with the pathogen at a ratio of
100:1 cfu ml-1, causing an almost complete inhibition of
urease activity. Strains were also screened for their performances
in in vitro tests such as adhesion ability to Caco-
2 cells, tolerance to low pH, bile salts, and simulated
digestion, which enabled the differences between strains to
be highlighted. Three strains, L. paracasei IMPC2.1 and L.
plantarum ITM21B and ITM5BG, met the main criteria for
selecting effective probiotics: the ability to inhibit the
pathogen Y. enterocolitica and, consequently, its urease
activity (ITM21B); survival of simulated digestion
(ITM21B and IMPC2.1); strong adhesion ability to enterocytes
and good survival at low pH and in the presence
of bile salts (ITM5BG and IMPC2.1). (literal)
