Klebsiella pneumoniae employs a type VI secretion system to overcome microbiota-mediated colonization resistance.

Microbial species must compete for space and nutrients to persist in the gastrointestinal (GI) tract, and our understanding of the complex pathobiont-microbiota interactions is far from complete. Klebsiella pneumoniae, a problematic, often drug-resistant nosocomial pathogen, can colonize the GI tract asymptomatically, serving as an infection reservoir. To provide insight on how K.

Nonselective beta blockade enhances gut microbiome diversity in a rodent model of trauma, hemorrhage, and chronic stress.

Background: Traumatic injury leads to gut dysbiosis with changes in microbiome diversity and conversion toward a "pathobiome" signature characterized by a selective overabundance of pathogenic bacteria. The use of non-selective beta antagonism in trauma patients has been established as a useful adjunct to reduce systemic inflammation. We sought to investigate whether beta-adrenergic blockade following trauma would prevent the conversion of microbiome to a "pathobiome" phenotype.
