Genetic and Phenotypic Characterization of Listeria monocytogenes Strains with Attenuated Virulence
Epidemiological studies have provided considerable evidence that Listeria monocytogenes trains differ in their ability and relative likelihood to caus~ human disease. Multiple mutations leading to premature stop codons (PMSCs) have been identified in the key L. monocytogenes virulence gene inIA, which codes for a surface protein that mediates the entry of L. monocytogenes into host cells. Mutat...
متن کاملGenetic 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 کاملPhenotypic and Genotypic Characterization of Atypical Listeria monocytogenes and Listeria innocua Isolated from Swine Slaughterhouses and Meat Markets
In the last decade, atypical Listeria monocytogenes and L. innocua strains have been detected in food and the environment. Because of mutations in the major virulence genes, these strains have different virulence intensities in eukaryotic cells. In this study, we performed phenotypic and genotypic characterization of atypical L. monocytogenes and L. innocua isolates obtained from swine slaughte...
متن کاملIsolation and Characterization of Lytic Bacteriophages from Wastewater against Listeria monocytogenes
Background and Aims: In the current study, two bacteriophages were isolated from the wastewater sources and characterized by lytic activity against the Listeria monocytogenes (L. monocytogenes) bacterium. Materials and Methods: 50 wastewater samples were collected from the disposal sites. The phages were isolated from the treated samples using the double agar overlay method with L. monocytoge...
متن کاملGenome comparison of Listeria monocytogenes serotype 4a strain HCC23 with selected lineage I and lineage II L. monocytogenes strains and other Listeria strains
More than 98% of reported human listeriosis cases are caused by specific serotypes within genetic lineages I and II. The genome sequence of Listeria monocytogenes lineage III strain HCC23 (serotype 4a) enables whole genomic comparisons across all three L. monocytogenes lineages. Protein cluster analysis indicated that strain HCC23 has the most unique protein pairs with nonpathogenic species Lis...
