There is growing evidence that anthropogenic sources of antibiotics and antimicrobial-resistant bacteria can spill over into natural ecosystems, raising questions about the role wild animals play in the emergence, maintenance, and dispersal of antibiotic resistance genes. In particular, we lack an understanding of how resistance genes circulate within wild animal populations, including whether...

During nonventilated storage of carrots, CO2 gradually accumulates to high levels and causes modifications in the carrot's microbiome toward dominance of Lactobacillales and Enterobacteriales. The lactic acid bacterium Leuconostoc mesenteroides secretes a slimy exudate over the surface of the carrots. The objective of this study was to characterize the slime components and the potential cause for...

Abstract Efflux pumps are recognized as an important mechanism for decreased susceptibility of benzalkonium chloride (BC) in Listeria monocytogenes. Previous studies showed that the efflux pump MdrL was overexpressed in L. monocytogenes exposed to BC. In the present work, we aimed to clarify the role of MdrL in tolerance to BC and environmental stresses including acid, alkali,...
