Listeria monocytogenes, a down-to-earth pathogen
Listeria monocytogenes is the causative agent of the food-borne life threatening disease listeriosis. This pathogenic bacterium received much attention in the endeavor of deciphering the cellular mechanisms that underlie the onset of infection and its ability to adapt to the food processing environment. Although information is available on the presence of L. monocytogenes in many environmental ...
متن کاملListeria monocytogenes: a foodborne pathogen.
Listeriosis, caused by Listeria monocytogenes, appears to be increasing in incidence worldwide. The disease is of great concern to the food industry. A recent outbreak in California was linked to the consumption of Mexican-style soft cheese and involved more than 300 cases, 30% of which were fatal. L. monocytogenes can be found in a variety of dairy products, leafy vegetables, fish and meat pro...
متن کاملPhotodynamic Inactivation of Food Pathogen Listeria monocytogenes
The aim of this study is to examine the possibility to inactivate food pathogen Listeria monocytogenes by nonthermal antimicrobial treatment – photosensitization. L. monocytogenes was incubated with 5-aminolevulinic acid (ALA) (7.5 mM) for 0–2 h to produce endogenous photosensitizers and then illuminated with visible light. The LED-based light source used for the illumination of L. monocytogene...
متن کاملListeria monocytogenes: An Emerging Food Borne Pathogen
There are many organisms secreted through milk, one of them is Listeria monocytogenes which causes significant public health problem. L. monocytogenes is the most important species in the genus Listeria creating human health hazard and having a worldwide distribution with an extensive host range which includes mammal, poultry, fish, crustacean and ticks. The name of the intracellular organism e...
متن کاملCD44-regulated intracellular proliferation of Listeria monocytogenes.
CD44 has been implicated in immune and inflammatory processes. We have analyzed the role of CD44 in the outcome of Listeria monocytogenes infection in murine bone marrow-derived macrophages (BMM). Surprisingly, a dramatically decreased intracellular survival of L. monocytogenes was observed in CD44(-/-) BMM. CD44(-/-) heart or lung fibroblast cultures also showed reduced bacterial levels. Moreo...
