Listeria monocytogenes, a Gram-positive bacterium, can cause meningitis after invading the human central nervous system. The blood-cerebrospinal fluid barrier (BCSFB), located at the epithelium of the choroid plexus, is a possible entry site for L. monocytogenes into the brain, and in vitro L. monocytogenes invades human choroid plexus epithelial papilloma (HIBCPP) cells. Although host cell signal transduction subsequent to infection by L. monocytogenes has been investigated, the role of mitogen-activated protein kinases (MAPK) is not clarified yet...

A 69-year-old woman presented with anorexia, fever, and vomiting. The patient was not a compromised host. She was finally diagnosed with <i>Listeria</i> meningitis and treated with ampicillin and gentamicin. However, her condition worsened over time. Non-contrast head CT showed ventricular dilatation. As a result, continuous right ventricular drainage was performed. Non-contrast MRI revealed hydrocephalus due to stenosis of the fourth ventricle. She underwent endoscopic third ventriculostomy(ETV)to improve cerebrospinal fluid circulation...

Listeria monocytogenes is a Gram-positive intracellular pathogen that causes spontaneous abortion in pregnant women, as well as septicemia, meningitis, and gastroenteritis, primarily in immunocompromised individuals. Although L. monocytogenes can usually be effectively treated with antibiotics, there is still around a 25% mortality rate with individuals who develop clinical listeriosis. Neutrophils are innate immune cells required for the clearance of pathogenic organisms, including L. monocytogenes The diverse roles of neutrophils during both infectious and noninfectious inflammation have recently gained much attention...

Listeria monocytogenes is a well-known cause of meningitis, colitis, and bacteremia; however, obstructive pyelonephritis caused by L. monocytogenes has never been reported. We herein report on a 90-year-old Japanese woman with obstructive pyelonephritis and bacteremia due to uterus carcinoma invading the ureter. She was admitted to our hospital complaining of fever and chills, and her physical examination revealed left costovertebral angle tenderness. Computed tomography showed hydronephrosis and complete ureteral obstruction due to tumor invasion...

PURPOSE: Various immunocompromised conditions increase the risk of meningitis caused by Listeria monocytogenes. However, the relative importance of these risk factors has not been well established. We determined the risk factors that predict meningitis due to L. monocytogenes compared to that caused by Streptococcus pneumoniae. METHODS: A nationwide multicenter case-control study was conducted in Korea. Cases of meningitis caused by L. monocytogenes between 1998 and 2013 were included...

BACKGROUND: Listeriosis caused by listeria monocytogenes (LM) is a potentially lethal foodborne infection of the central nervous system (CNS) and the third most common cause of bacterial meningitis. Foods most commonly implicated are soft cheeses, raw or ready-to-eat meat and pre-processed foods. The incubation time is between 11 and 70 days. Rarely LM rhombencephalitis (RE) can occur, which typically has a biphasic course with non- specific prodromal symptoms like fever, malaise, fatigue, headache, nausea and vomiting followed by cranial nerve palsies, ataxia and hemi- or tetraparesis...

BACKGROUND: Solid organ transplant (SOT) recipients are at risk of infections of the central nervous system. However, the incidence and clinical course of bacterial meningitis in SOT recipients are unclear. We studied occurrence, disease course, and prognosis of bacterial meningitis in SOT recipients in the Netherlands. METHODS: All patients with a medical history of solid organ transplantation were selected from our nationwide prospective cohort study on community-acquired bacterial meningitis in patients >16 years old, performed from March 1, 2006 to October 31, 2014...

Listeria monocytogenes is a Gram-positive bacillus and facultative intracellular bacterium whose transmission occurs mainly through the consumption of contaminated food, L. monocytogenes invades the host cells using various protein and can escape to the human T-cell immune system by cell-to-cell spreading. If the infection is not controlled at the stage in which the bacterium is in the liver, for instance, due to a severe immunodepression, a secondary bacteraemia can be developed and L. monocytogenes reaches the preferred sites transgressing the blood-brain barrier or the placental barrier...

Invasive Listeria monocytogenes infections carry a high mortality despite antibiotic treatment. The rareness of the infection makes it difficult to improve antibiotic treatment through randomized clinical trials. This observational study investigated clinical features and outcome of invasive L. monocytogenes infections including the efficacy of empiric and definitive antibiotic therapies. Demographic, clinical and biochemical findings, antibiotic treatment and 30-day mortality for all episodes of L. monocytogenes bacteraemia and/or meningitis were collected by retrospective medical record review in the North Denmark Region and the Capital Region of Denmark (17 hospitals) from 1997 to 2012...

Rapid diagnosis and treatment of infectious meningitis and encephalitis are critical to minimize morbidity and mortality. Comprehensive testing of cerebrospinal fluid (CSF) often includes Gram stain, culture, antigen detection, and molecular methods, paired with chemical and cellular analyses. These methods may lack sensitivity or specificity, can take several days, and require significant volume for complete analysis. The FilmArray Meningitis/Encephalitis (ME) Panel is a multiplexed in vitro diagnostic test for the simultaneous, rapid (∼1-h) detection of 14 pathogens directly from CSF specimens: Escherichia coli K1, Haemophilus influenzae, Listeria monocytogenes, Neisseria meningitidis, Streptococcus pneumoniae, Streptococcus agalactiae, cytomegalovirus, enterovirus, herpes simplex virus 1 and 2, human herpesvirus 6, human parechovirus, varicella-zoster virus, and Cryptococcus neoformans/Cryptococcus gattii We describe a multicenter evaluation of 1,560 prospectively collected CSF specimens with performance compared to culture (bacterial analytes) and PCR (all other analytes)...

The prevalence of Listeria monocytogenes infection has been characterized as rare in Thailand. Within one month, 3 cases of listeriosis were seen at Vachira Phuket Hospital in Phuket, Thailand. Two cases were neonates with septicemia, of which one made an uneventful recovery and the other expired. The third case was an eleven-year-old boy with meningitis who also succumbed to his illness. All isolated L. monocytogenes were sensitive to ampicillin. An outbreak investigation revealed no L. monocytogenes contamination in tested food sources in Phuket...

Listeria monocytogenes (LM) is an aerobic, motile, intracellular gram-positive bacterium. Most invasive systemic infections caused by LM are commonly seen in patients at both extremes of age, during pregnancy or in immunocompromised hosts. Common clinical manifestations of LM infection in immunocompromised adults are bacteremia, infections of central nervous system, such as meningitis, and self-limiting febrile gastroenteritis. Focal infections of listeria are rare, especially cholecystitis, with only few cases reported in the last 33 years...

Listeriosis and toxoplasmosis are foodborne illnesses that can have long-term consequences when contracted during pregnancy. Listeriosis is implicated in stillbirth, preterm labor, newborn sepsis, and meningitis, among other complications. Toxoplasmosis is associated with blindness, cognitive delays, seizures, and hearing loss, among other significant disabilities. Healthcare providers who understand the fundamentals of Listeria and Toxoplasma infection will have the tools to identify symptoms and high-risk behaviors, educate women to make safer decisions, and provide anticipatory guidance if a pregnant woman would become infected with either of these foodborne illnesses...

Infection by Listeria monocytogenes (Lm) causes serious sepsis and meningitis leading to mortality in neonates. This work explored the ability of CD11c(high) lineage DCs to induce CD8+ T-cell immune protection against Lm in mice before 7 days of life, a period symbolized by the absence of murine IL-12p70-producing CD11c(high)CD8α+ dendritic cells (DCs). We characterized a dominant functional Batf3-dependent precursor of CD11c(high) DCs that is Clec9A+CD205+CD24+ but CD8α- at 3 days of life. After Lm-OVA infection, these pre-DCs that cross-present Ag display the unique ability to produce high levels of IL-12p40 (not IL-12p70 nor IL-23), which enhances OVA-specific CD8+ T cell response, and regulatory IL-10 that limits OVA-specific CD8+ T cell response...

Listeria monocytogenes is a facultative anerobic, gram-positive bacillus that is isolated from the soil, vegetables, and wild or domestic animals. Listeria infection is usually found in the older adults, immunocompromised patients, pregnant women, and newborns, whereas it is rare in healthy infants and children. Listeria monocytogenes may cause meningitis, meningoencephalitis, brain abscess, pyogenic arthritis, osteomyelitis, and liver abscess in children. The course of meningoencephalitis by Listeria is often severe and even fatal...

BACKGROUND AND OBJECTIVES: Although listeriosis is rare in infants, it is common for young infants with suspected serious bacterial infection to be treated empirically with agents selected, in part, for their activity against Listeria monocytogenes. Our objectives were to describe the recent epidemiology of hospital discharges for listeriosis among infants in the United States and to precisely estimate the incidence of listeriosis according to infant age and meningitis status. METHODS: We generated national estimates for listeriosis discharges in each of the 6 years for which samples were available in the Kids' Inpatient Database during the period 1997-2012...
