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...

neurologic and psychologic complications are usually related to drug toxicity, infections or symptoms induced by deterioration of renal allograft function. metabolic encephalopathy, hypertensive encephalopathy, cerebrovascular events, and new-onset seizures have all been reported in organ-transplant recipients. infections can be caused by listeria, cryptococcus, nocardia, aspergillus and mucor....

Listeria monocytogenes is a very important life-threatening bacteria in certain risk groups such as neonates, pregnant women, elderly people, transplant recipients and others with impaired cell-mediated immunity. However, its infections are very rare in healthy children. Reports of listeriosis in newborn period are limited. We report a case of neonatal listeriosis with erythematous rash, intrac...

INTRODUCTION Listeria monocytogenes (LM) is known to cause severe invasive disease in pregnant women and in newborns. Fortunately, despite the wide natural distribution of this pathogen, clinically overt neonatal infections occurs rarely. As a consequence, listeriosis is not always considered for early onset neonatal infection, especially when blood culture is negative. Indeed, identification o...

For example, a case-control study of sporadic infections enabled an unprecedented response time during the large U.S. listeriosis outbreak in 2011. Data collected by the Listeria Initiative led to the identification of an association with cantaloupe within days rather than weeks or months (CDC, 2011a). We estimate that the commercial recall of the implicated cantaloupe just 12 days from outbrea...

Listeria monocytogenes is a remarkably successful food-borne pathogen. It is capable a) of surviving and proliferating under conditions that exist within the food chain, such as at low temperatures, high salt and low pH and b) of colonizing animal host tissues after ingestion of contaminated food, causing opportunistic infections mainly, but not exclusively, in immunocompromised hosts. The ulti...

Cutaneous infections due to Listeria monocytogenes are rare. Typically, infections manifest as nonpainful, nonpruritic, self-limited, localized, papulopustular or vesiculopustular eruptions in healthy persons. Most cases follow direct inoculation of the skin in veterinarians or farmers who have exposure to animal products of conception. Less commonly, skin lesions may arise from hematogenous di...

It has been proposed that long-lived memory T cells generated by vaccination or infection reside within a memory compartment that has a finite size. Consequently, in a variety of acute infection models interclonal competition has been shown to lead to attrition of preexisting memory CD8+ T cells. Contrary to expectations, therefore, we found that chronic Leishmania donovani infection of Listeri...
