Microtiter Plate Assay for Assessment of Listeria monocytogenes Biofilm Formation
ABSTRACT Listeria monocytogenes has the ability to form biofilms on food-processing surfaces, potentially leading to food product contamination. The objective of this research was to standardize aExpand

YidC mediates membrane protein insertion in bacteria
The basic machinery for the translocation of proteins into or across membranes is remarkably conserved from Escherichia coli to humans. In eukaryotes, proteins are inserted into the endoplasmicExpand

Listeria monocytogenes lineages: Genomics, evolution, ecology, and phenotypic characteristics.
Listeria monocytogenes consists of at least 4 evolutionary lineages (I, II, III, and IV) with different but overlapping ecological niches. Most L. monocytogenes isolates seem to belong to lineages IExpand

Ribotypes and virulence gene polymorphisms suggest three distinct Listeria monocytogenes lineages with differences in pathogenic potential.
A total of 133 Listeria monocytogenes isolates were characterized by ribotyping and allelic analysis of the virulence genes hly, actA, and inlA to uncover linkages between independent phylogeneticExpand

Ecology and Transmission of Listeria monocytogenes Infecting Ruminants and in the Farm Environment
ABSTRACT A case-control study involving 24 case farms with at least one recent case of listeriosis and 28 matched control farms with no listeriosis cases was conducted to probe the transmission andExpand

Listeria monocytogenes persistence in food-associated environments: epidemiology, strain characteristics, and implications for public health.
Over the last 10 to 15 years, increasing evidence suggests that persistence of Listeria monocytogenes in food processing plants for years or even decades is an important factor in the transmission ofExpand

Culture independent analysis of ileal mucosa reveals a selective increase in invasive Escherichia coli of novel phylogeny relative to depletion of Clostridiales in Crohn's disease involving the ileum
Intestinal bacteria are implicated increasingly as a pivotal factor in the development of Crohn's disease, but the specific components of the complex polymicrobial enteric environment driving theExpand

Alternative Sigma Factors and Their Roles in Bacterial Virulence
SUMMARY Sigma factors provide promoter recognition specificity to RNA polymerase holoenzyme, contribute to DNA strand separation, and then dissociate from the core enzyme following transcriptionExpand

Molecular Studies on the Ecology of Listeria monocytogenes in the Smoked Fish Processing Industry
ABSTRACT We have applied molecular approaches, including PCR-based detection strategies and DNA fingerprinting methods, to study the ecology ofListeria monocytogenes in food processing environments.Expand

Listeria monocytogenes Isolates from Foods and Humans Form Distinct but Overlapping Populations
ABSTRACT A total of 502 Listeria monocytogenes isolates from food and 492 from humans were subtyped by EcoRI ribotyping and PCR-restriction fragment length polymorphism analysis of the virulence geneExpand
