background: the use of dendritic cells (dcs) as a cellular adjuvant provides a promis-ing approach in immunotherapy of cancer. it has been demonstrated that listeria mono-cytogenes activated dcs pulsed ex vivo with tumor antigens trigger a systemic th1-biased specific immune response and a single dose of this vaccine will cause a consider-able anti tumor immunity. objective: the present study w...
This study was carried out on 426 samples of raw meats collected from butcheries and supermarkets in Casablanca, Morocco. The samples were examined for the occurrence of Listeria species. Strains of Listeria monocytogenes were characterized by several biochemical tests and confirmed by polymerase chain reaction (PCR). β-hemolytic cultures and nonhemolytic isolates were tested for biochemical pr...
RESUMEN. Presencia de Listeria monocytogenes en vegetales frescos. Introducción. En los últimos años, se ha dado un incremento en el hecho de consumir vegetales frescos como parte de una dieta sana, pero no se puede descartar el que estos pueden actuar como vehículos de microorganismos patógenos, como Listeria monocytogenes. Material y métodos. Se evaluó la presencia de Listeria monocytogenes e...

Purkrtová S., Turoňová H., Pilchová T., Demnerová K., Pazlarová J. (2010): Resistance of Listeria monocytogenes biofilms to disinfectants. Czech J. Food Sci., 28: 326–332. We studied the optimal conditions for the biofilm development by Listeria monocytogenes on a model system represented by microtiter plates, and also for determined some effective disinfectant agents. Listeria monocytogenes AT...
Listeria species are widely distributed in environment and L. monocytogenes are the causal agent of Listeriosis, the disease that can be serious and fatal to human and animals. The objectives of this study were to detect, isolate and identify Listeria monocytogenes from retail broiler chicken ready to eat meat products in restaurants-Khartoum state, Sudan. A total of 250 retail broiler chicken ...
The possibility of modeling the cross-contamination of Listeria species, total Listeria monocytogenes, or specific L. monocytogenes strains using a quantitative mathematical model using Monte Carlo simulation techniques is proposed. This article illustrates this approach using 2 different models: one that tracks L. monocytogenes number and prevalence for 4 different strains (Model I) and one th...
Conventional routine detection of Listeria monocytogenes in food products requires at least 7 days. Thus, the rapid technology for detection of L. monocytogenes is of the utmost importance and urgent necessity. This study aims to develop the rapid DNA extraction for detection of L. monocytogenes by using PCR assay. After DNA extraction of L. monocytogenes, three methods including the deionized ...
most birds probably can carry listeria spp. asymptomatically in their intestines with varying prevalence and can transmit the pathogens to human. the genus-listeria has two pathogenic species namely, l. monocytogenes and l. ivanovii. l. monocytogenes is a well-known cause of abortion, encephalitis and septicaemia in man and animals. l. ivanovii is an animal pathogen and in rare cases cause huma...
