Characterization of lactic acid bacteria isolated from the poultry intestinal environment with anti-Salmonella activity in vitro.

The purpose of this research was the genotypic identification of lactic acid bacteria (LAB), isolated from the gastrointestinal tract (GIT) of healthy adult birds, and the study of their safety regarding antibiotic resistance, physiological and functional properties involved in the colonization of the GIT of poultry, and Salmonella exclusion, as members of a potential mixed probiotic supplement for poultry. The nucleotidic sequence from Lactobacillus crispatus P1, L. animalis L3, and Enterococcus faecium CRL 1385 (ex-J96) showed 100, 99.
