conclusions the leptin can also be used for the treatment of severe and intractable l. monocytogenes and e. coli infection. results our data demonstrates that leptin is able to induce cd11b expression on neutrophils but this induction is significantly less than l. monocytogenes. indeed, cells treated with leptin had lower amounts of apoptosis compared with untreated cells. the highest amount of...

Listeria monocytogenes, an important food-borne pathogen, causes listeriosis and is widely distributed in many different environments. In a previous study, we developed a novel enrichment broth containing D-allose that allows better isolation of L. monocytogenes from samples. However, the mechanism of D-allose utilization by L. monocytogenes remains unclear. In the present study, we determined ...

Listeria monocytogenes is a species of foodborne pathogen often related to foods, such as poultry, ready-to-eat products, fruits, and vegetables. The culture method is a standard procedure for the detection of bacteria in food products. The real-time quantitative PCR (qPCR) technique can be used for the quantification of foodborne pathogens. The current research was aimed to assess...

Listeria monocytogenes is a food-borne bacterial pathogen that causes a wide spectrum of diseases, such as meningitis, septicemia, abortion, and gastroenteritis, in humans and animals. Among the 13 L. monocytogenes serovars described, invasive disease is mostly associated with serovar 4b strains. To investigate the genetic diversity of L. monocytogenes strains with different virulence potential...

Listeria monocytogenes is a Gram positive ubiquitous psychrotrophic bacterium responsible for foodborne infections worldwide. L. monocytogenes is capable of growing at refrigeration temperatures in high salt and acid foods. In this study a response surface methodology was used to determine the effects and interactions of pH (4 to 10), temperature (4 oC to 40 oC) and ozonation time (5 seconds to...

The present study was undertaken to determine the prevalence of Listeria monocytogenes in selected raw materials and food products of animal origin in Poland. In total, 1118 fish and fish products, and 2172 meat and meat products samples were examined by using ISO culture method. Out of 478 pork samples examined 45 (9.41%) contained L. monocytogenes. Out of the 317 samples of beef the microorga...

OBJECTIVE There are many studies supporting the role of certain asymptomatic infections such as Listeria monocytogenes (L. monocytogenes) in spontaneous abortion. In some cases, latent listeriosis may complicate the pregnancy, and serologic tests can, therefore, be used to detect the disease. This study was designed to assess the relationship between seropositivity for L. monocytogenes and spon...

Invasion of endothelial tissues may be crucial in a Listeria monocytogenes infection leading to meningitis and/or encephalitis. Internalization of L. monocytogenes into endothelial cells has been previously demonstrated by using human umbilical vein endothelial cells as a model system. However, during the crossing of the blood-brain barrier, L. monocytogenes most likely encounters brain microva...

BACKGROUND Listeria monocytogenes, an intracellular foodborne pathogen, infects immunocompromised hosts. The primary route of transmission is through contaminated food. In the gastrointestinal tract, it traverses the epithelial barrier through intracellular or paracellular routes. Strategies to prevent L. monocytogenes entry can potentially minimize infection in high-risk populations. Listeria ...
