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...

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 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...

Listeria monocytogenes is a foodborne pathogen of significant concern to the agricultural and food processing industry because of its ability to grow and persist in cool and moist environments and its association with listeriosis, a disease with a very high mortality rate. Although there have been no listeriosis outbreaks attributed to fresh mushrooms in the United States, retail surveys and re...

Listeria monocytogenes is a human intracellular pathogen able to colonize host tissues after ingestion of contaminated food, causing severe invasive infections. In order to gain a better understanding of the nature of host-pathogen interactions, we studied the L. monocytogenes genome expression during mouse infection. In the spleen of infected mice, approximately 20% of the Listeria genome is d...
