Tissue-specific microbiota dictates the competitive dynamics of <i>listeria</i> species colonization.

ABSTRACT: The genus Listeria is heterogeneous and contains pathogenic and nonpathogenic species. Pathogenic L. monocytogenes and L. ivanovii have different environmental distributions, infect different hosts, and cause distinct syndromes. Here, we evaluated whether responses of different Listeria species to diverse host niches contribute to virulence heterogeneity and influence their environmental distribution. We assessed resistance to gastric and intestinal fluids, gut and uterus microbiota, and semen. L. monocytogenes was more resistant than L. ivanovii in gastric fluid, whilst L. seeligeri and L. valentina showed an intermediate phenotype. All the tested Listeria species resisted the intestinal fluid. Gut microbial communities outcom
