Ozone Inactivation of Listeria Monocytogenes
… strain to ozone exposure indicates that L. monocytogenes requires SOD for survival under oxidative stress as a trigger of the detoxification process. Ozone injury and recovery studies showed that L. monocytogenes required RNA and protein synthesis and oxidative phosphorylation for cellular …

How did Listeria monocytogenes become pathogenic?
Listeriae are Gram positive, facultative, saprophytic bacteria capable of causing opportunistic infections in humans and animals. This thesis presents three separate lines of inquiries that can lead to the eventual convergence of a global view of Listeria as pathogen in the light of evolution, …

Interaktion von Listeria monocytogenes mit Endothelzellen
Listeria monocytogenes überwindet endotheliale Barrieren, um eine Meningitis oder Encephalitis auszulösen. Das Hindurchtreten durch diese Barriere könnte über die Invasion von Endothelzellen durch Listerien aus dem Blut und anschließender Freisetzung der Bakterien ins Gehirn erfolgen. In den ersten …

Interaktion humaner dendritischer Zellen mit Listeria monocytogenes
… dieser Arbeit wurde die Interaktion von DZ mit Listeria monocytogenes untersucht. Es konnte gezeigt werden, dass L. monocytogenes effizient in unreife, humane DZ aufgenommen wird. Die Phagozytoserate von L. monocytogenes unter Zugabe von humanem Plasma war wesentlich höher als im Plasma-freien …

Copper tolerance of Listeria monocytogenes strain DRDC8.
Listeria monocytogenes is one of the most important food-borne pathogens due to the severity of the disease it can cause. While the virulence factors required for effective colonisation and infection of mammalian hosts have been well described, other genes may modulate disease persistence. For L. …

How Listeria monocytogenes crosses host cell barriers
Listeria monocytogenes is a bacterial pathogen that causes listeriosis, a severe food-borne illness that can cause severe complications and mortality in immunocompromised or pregnant people. Listeria is able to cross several host barriers to cause severe disease, including the intestinal barrier, …

Modelling the behaviour of Listeria monocytogenes in cheese
… processing step. In this work, the behaviour of Listeria monocytogenes during cheesemaking and ripening was studied given a milk contamination or surface cross-contamination scenario. When milk was contaminated, L. monocytogenes initiated growth with a different probability during cheesemaking …

Potential Antimicrobials for Controlling Listeria monocytogenes in Frankfurters
<p>Listeria monocytogenes is a pathogenic microorganism that causes Listeriosis. Listeriosis is a highly mortal disease with approximately 20% mortality rate. Listeria is psychrophilic, therefore it is able to survive in the refrigerator. This affects foods at cool storage such as fresh produce and …

LncRNA discovery in the Listeria monocytogenes infection model
… and uncover their physiological relevance during Listeria monotocytogenes infection. To this end, an RNA-Seq dataset of Listeria-infected HeLa cells was subjected to several variations of data analysis lncRNA discovery pipelines. Potential lncRNA functioning was hypothesized using the Rinn & Chang …

Spontaneous Rosette Formation In Mice Immunized With Listeria Monocytogenes
… study determined the effect of immunization with Listeria monocytogenes upon spontaneous rosette formation (SRF) between BALB/c mouse spleen lymphocytes and C57BL mouse erythrocytes. It was found that SRF in nonimmunized mice ranged from 8 to 20 percent with a mean value of 12.0 + 2.1 percent. …

Essential features of a PrfA-dependent : promoter of Listeria monocytogenes
… facultative intracellular pathogen Listeria monocytogenes is the causal agent of listeriosis. Most of well-known virulence genes are controlled by PrfA that belongs to the Crp-Fnr family of transcriptional activators. A PrfA-mediated transcription initiating at a virulence gene …

The phenotypic and molecular responses of Listeria monocytogenes to stressors
Listeria monocytogenes is a food-borne pathogen and the causative agent of listeriosis, a severe infection resulting in septicaemia, meningitis and still birth. Infection typically arises through the consumption of contaminated foodstuffs. L. monocytogenes is a hardy organism which can survive …

Ozone Inactivation and Attachment of Listeria Monocytogenes to Abiotic Surfaces
L. monocytogenes 104035 and LO28 wild-type strains showed motility when gown at both 24 and 37°C although flagellin production was reduced during growth at 37°C. Both the wild-types and flagella minus mutants showed similar cells counts when attached over time on polystyrene microtiter …

Temperature adaptation and plasmid transformation in Listeria monocytogenes ATCC 7644
As a recently recognized food-borne pathogen, L. monocytogenes has caused great concerns in food industry due to its ability to survive and grow in many refrigerated foods. The first part of this thesis research was to examine the ability of L. monocytogenes to adapt to changing environmental …

Interaktion des Proteins ActA von Listeria monocytogenes mit dem Wirtszellprotein LaXp180
Listeria monocytogenes, ein fakultativ intrazellulärer Krankheitserreger, besitzt die Fähigkeit, Wirtszellen zu penetrieren, sich in ihnen zu vermehren, sich intrazellulär zu bewegen und auch benachbarte Zellen direkt zu infizieren. Die intrazelluläre Fortbewegung erfolgt durch Polymerisation von …
