Listeria monocytogenes is a facultative intracellular foodborne pathogen that can cause listeriosis in humans and animals. L. monocytogenes LM201 was isolated from foodstuff. The draft genome sequence of strain LM201 provides the genetic basis for the application of this strain in biotechnological vaccine production.

Listeria monocytogenes sequence type 204 (ST204) strains have been isolated from a range of food, environmental, and clinical sources in Australia. This study describes the draft genome sequences of 15 isolates collected from meat and dairy associated sources.
Listeria monocytogenes after Infection with T Cells δ / γ Responses in the Absence of Exaggerated Proinflammatory and Th1
Background: Gp96 is the cellular receptor for Vip, a Listeria monocytogenes surface protein. The molecular details of Gp96-Vip interaction are unknown. Results: Cell surface expression of Gp96 increases upon Listeria infection. Gp96 Nterminal is required for Vip interaction. Conclusion: Gp96 N-terminal domain is exposed to the extracellular milieu and is required for optimal Listeria entry. Sig...
In September 2015, PulseNet, the national molecular subtyping network for foodborne disease surveillance, identified a cluster of Listeria monocytogenes (Listeria) clinical isolates indistinguishable by two-enzyme pulsed-field gel electrophoresis (PFGE) pattern combination and highly related by whole-genome multilocus sequence typing (wgMLST). A case was defined as isolation of Listeria with th...
A molecular method based on restriction fragment length polymorphism (RFLP) of PCR-amplified fragments of the 23S rRNA gene was designed to rapidly identify Listeria strains to the species level. Two fragments (S1, 460 bp, and S2, 890 bp) were amplified from boiled DNA. S2 was cut with the restriction enzymes XmnI or CfoI and, if needed, S1 was digested by either AluI or ClaI. This method was f...
Food contaminated with human pathogens, such as Salmonella spp. and Listeria monocytogenes, frequently causes outbreaks of foodborne illness. Consumer concern over the use of synthesized antimicrobials to enhance microbial food safety has led to a search of natural alternatives. The objectives of this study were to evaluate the antimicrobial activity of various types of sophorolipids (SLs) and ...
A total of 154 samples of marine (n=51) and freshwater fish (n=103) were obtained from fish markets in Elazig Province of eastern Turkey. These samples were tested for Campylobacter, Listeria and Salmonella using culturing and biochemical methods. Campylobacter failed to be detected in any freshwater or marine fish samples. Listeria was detected in 22 and 14 of gill and skin samples from freshw...
Introduction: Listeria monocytogenes is a pathogen bacteria transmitted by food stuffs. Due to the lack of information about contamination of retail chicken meat to Listeria monocytogenes in Iran, this study aimed to determine the prevalence and antibiotic resistance of this bacterium in retail chicken meat in Yazd, Iran. Materials and Methods: This cross-sectional descriptive study was conduc...
