Genetic characterization of plasmid-associated triphenylmethane reductase in Listeria monocytogenes.
The enzyme triphenylmethane reductase (TMR) reduces toxic triphenylmethane dyes into colorless, nontoxic derivatives, and TMR-producing microorganisms have been proposed as bioremediation tools. Analysis of the genome of Listeria monocytogenes H7858 (1998-1999 hot dog outbreak) revealed that the plasmid (pLM80) of this strain harboring a gene cassette (bcrABC) conferring resistance to benzalkon...
متن کاملGenetic Characterization of Plasmid - Associated Triphenylmethane Reductase 1 in Listeria monocytogenes
27 The enzyme triphenylmethane reductase (TMR) reduces toxic triphenylmethane dyes into 28 colorless, non-toxic derivatives, and TMR-producing microorganisms have been proposed as 29 bioremediation tools. Analysis of the genome of Listeria monocytogenes H7858 (1998-1999 hot 30 dog outbreak) revealed that the plasmid (pLM80) of this strain harboring a gene cassette 31 (bcrABC) conferring resista...
متن کاملGenetic characterization of plasmid-associated benzalkonium chloride resistance determinants in a Listeria monocytogenes strain from the 1998-1999 outbreak.
Quaternary ammonium compounds such as benzalkonium chloride (BC) are widely used as disinfectants in both food processing and medical environments. BC-resistant strains of Listeria monocytogenes have been implicated in multistate outbreaks of listeriosis and have been frequently isolated from food processing plants. However, the genetic basis for BC resistance in L. monocytogenes remains poorly...
متن کاملPlasmid-mediated streptomycin resistance of listeria monocytogenes.
A strain of streptomycin-resistant Listeria monocytogenes LM35 isolated from imported frozen beef was examined in this study. In conjugation studies, the L. monocytogenes LM35 strain harbouring two plasmids of 54, 3.0, 2.8 and 2.7 kilobase was used as the donor and streptomycin-sensitive and plasmidless L. monocytogenes LM65 and LM100 strains as the recipients. Streptomycin resistance was trans...
متن کاملEpidemiological burden of Listeria monocytogenes in Iran
Objective(s): Listeria monocytogenes is a foodborne pathogenic bacteria causing the infection listeriosis, which possibly affects all people, particularly immunocompromised persons and pregnant women. This microorganism can be found in several processed foods, dairy products, raw milk, meat and fish products, seafoods, eggs, fruits, and vegetables. This review discusses about the epidemiologica...
