Tn6188 - A Novel Transposon in Listeria monocytogenes Responsible for Tolerance to Benzalkonium Chloride
Controlling the food-borne pathogen Listeria (L.) monocytogenes is of great importance from a food safety perspective, and thus for human health. The consequences of failures in this regard have been exemplified by recent large listeriosis outbreaks in the USA and Europe. It is thus particularly notable that tolerance to quaternary ammonium compounds such as benzalkonium chloride (BC) has been ...
متن کاملBenzalkonium chloride and heavy-metal tolerance in Listeria monocytogenes from retail foods.
Phenotypic and genotypic tolerance in 71 Listeria monocytogenes isolates from different varieties of foods to benzalkonium chloride (BC) and cadmium were investigated by susceptibility test and molecular methods. To investigate the role of efflux pumps in BC tolerance, reserpine, an efflux pump inhibitor, was added to the BC tolerant strains. Tolerance to BC and cadmium were 26.8% (19/71) and 4...
متن کاملConservation and distribution of the benzalkonium chloride resistance cassette bcrABC in Listeria monocytogenes.
Analysis of a panel of 116 Listeria monocytogenes strains of diverse serotypes and sources (clinical, environment of food processing plants, and food) revealed that all but one of the 71 benzalkonium chloride-resistant (BC(r)) isolates harbored bcrABC, previously identified on a large plasmid (pLM80) of the 1998-1999 hot dog outbreak strain H7858. In contrast, bcrABC was not detected among BC-s...
متن کاملEnvironmental and physico-chemical factors induce VBNC state in Listeria monocytogenes.
Investigations of bacterial survival in natural environments have indicated that some organisms lose culturability on appropriate media under certain conditions and yet still exhibit signs of metabolic activity and thus viability. This reproducible loss of culturability in many bacterial species led to the description of a "Viable But Non Culturable" (VBNC) state. The purpose of this article is...
متن کاملBenzalkonium tolerance genes and outcome in Listeria monocytogenes meningitis
OBJECTIVES Listeria monocytogenes is a food-borne pathogen that can cause meningitis. The listerial genotype ST6 has been linked to increasing rates of unfavourable outcome over time. We investigated listerial genetic variation and the relation with clinical outcome in meningitis. METHODS We sequenced 96 isolates from adults with listerial meningitis included in two prospective nationwide coh...
