Identification of poultry commensal bacteria with the ability to inhibit the growth of Salmonella enterica serovar Typhimurium in co-culture.

ABSTRACT:

Background

The widespread increase of antibiotic resistant bacteria (ARB) in agriculture has led to an interest in improving the competitive exclusion ability of the microbiota in livestock through the application of probiotics. In this study, we examined a collection of gram-negative bacteria isolated from healthy chickens for their ability to inhibit the growth of Salmonella enterica serovar Typhimurium.

Methods

Twenty-five bacteria isolated from healthy chickens were mixed at a 1:1 or a 10:1 ratio with S. enterica ser. Typhimurium and grown overnight in co-culture on a solid media that contained bile salt. The S. enterica in each co-culture was quantified using on Salmonella Shigella Agar (SSA) to determine which isolates can inhibit the growth of S. enterica in vitro. Is
