Listeria rhombencephalitis (LRE) is a rare encephalitis of the hindbrain that can present with a variety of neurological symptoms. It is a diagnostic challenge, but prompt antimicrobial therapy is important to prevent high rates of mortality and morbidity. We report two cases of LRE, with several contrasting clinical features and different disease courses. Despite being rare, it is important to...

fully mature dendritic cells (dcs) play pivotal role in inducing immune responses and converting naïve t lymphocytes into functional th1 cells. we aimed to evaluate listeria monocytogenes-derived protein fractions to induce dc maturation and stimulating t helper (th)1 immune responses. in the present study, we fractionated listeria monocytogenes-derived proteins by adding of ammonium sulfate in...

We present the complete genomes of Listeria ivanovii subsp. ivanovii WSLC 3010 (ATCC 19119(T)), Listeria ivanovii subsp. londoniensis WSLC 30151 (SLCC 8854), and Listeria ivanovii subsp. londoniensis WSLC 30167 (SLCC 6032), representing the type strain of the species and two strains of the same serovar but different properties, respectively.

Listeria monocytogenes is the causative bacteria of listeriosis, which has a higher mortality rate than that of other causes of food poisoning. Listeria spp., of which L. monocytogenes is a member, have been isolated from food and manufacturing environments. Several methods have been published for identifying Listeria spp.; however, many of the methods cannot identify newly categorized Listeria...

Delicatessen meats are reported to be the leading vehicle of foodborne listeriosis in the United States. Listeria monocytogenes can reach high numbers in these products during storage, and the growth rate is largely dictated by product formulation and storage temperature. To assess the impact of product age on Listeria growth, five commercial brands each of cured and uncured turkey breast, ham...

A 51-year-old Caucasian woman with Listeria monocytogenes meningitis was treated and discharged after an uncomplicated course. Her medical history included immunosuppressive treatment with prednisolone and azathioprine for autoimmune hepatitis. A diagnostic work-up after the meningitis episode revealed that she had low levels of the IgG4 subclass. To our knowledge, this is the first case report...

Cross-presentation is now recognized as a major mechanism for initiating CD8 T cell responses to virus and tumor antigens in vivo. It provides an elegant mechanism that allows relatively few Dendritic cells (DCs) to initiate primary immune responses while avoiding the consumptive nature of pathogenic infection. CD8 T cells play a major role in anti-bacterial immune responses; however, the contr...
