Beneficial effects of a strain of Lactobacillus paracasei subsp. paracasei in Staphylococcus aureus-induced intestinal and colonic injury.

Objectives: The aim of this study was to investigate the in vitro and in vivo anti-staphylococcal activity of a lactic acid bacterial strain and its effect on the intestinal histological damage caused by Staphylococcus aureus infection.

Methods: Lactobacillus paracasei subsp. paracasei was isolated in our laboratory from breastfed newborn feces and identified phenotypically and genotypically.
