Listeria Pathogenesis and Molecular Virulence Determinants
TLDR
The molecular determinants of Listeria virulence and their mechanism of action are described and the current knowledge on the pathophysiology of listeriosis and the cell biology and host cell responses to Listersia infection is summarized.
Comparative Genomics of Listeria Species
TLDR
A large number of predicted genes encoding surface and secreted proteins, transporters, and transcriptional regulators are found, consistent with the ability of both species to adapt to diverse environments.
Transcriptome analysis of Listeria monocytogenes identifies three groups of genes differently regulated by PrfA
TLDR
A whole‐genome array based on the complete genome sequence of Listeria monocytogenes strain EGDe is constructed and it is suggested that PrfA may directly or indirectly activate different sets of genes in association with different sigma factors.
Nucleotide sequence of the lecithinase operon of Listeria monocytogenes and possible role of lecithinase in cell-to-cell spread
The lecithinase gene of the intracellular pathogen Listeria monocytogenes, plcB, was identified in a 5,648-bp DNA fragment which expressed lecithinase activity when cloned into Escherichia coli. This…
The PrfA virulence regulon.
A Gly145Ser substitution in the transcriptional activator PrfA causes constitutive overexpression of virulence factors in Listeria monocytogenes
TLDR
Trans-complementation experiments with PrfA-deficient mutants demonstrated that the Gly145Ser prfA allele causes overexpression of virulence factors in L. monocytogenes, to the levels found in the virulence factor-overexpressing variants.
Pathogenicity islands and virulence evolution in Listeria.
Pleiotropic control of Listeria monocytogenes virulence factors by a gene that is autoregulated
TLDR
The results demonstrate that since prfA controls plcA transcription, it also regulates its own synthesis.
The Genome of a Pathogenic Rhodococcus: Cooptive Virulence Underpinned by Key Gene Acquisitions
TLDR
A mechanism of virulence evolution based on the cooption of existing core actinobacterial traits, triggered by key host niche–adaptive HGT events is suggested, and is tested by investigating R. equi virulence plasmid-chromosome crosstalk, by global transcription profiling and expression network analysis.
Evolution of the Rhodococcus equi vap Pathogenicity Island Seen through Comparison of Host-Associated vapA and vapB Virulence Plasmids
ABSTRACT The pathogenic actinomycete Rhodococcus equi harbors different types of virulence plasmids associated with specific nonhuman hosts. We determined the complete DNA sequence of a vapB +…
