Listeria monocytogenes only occasionally causes bacterial meningitis in immunocompetent children. We report a case of L. monocytogenes meningitis associated with rotavirus gastroenteritis. The patient was a previously healthy 20-month-old girl who was admitted because of sustained fever and lethargy after suffering from gastroenteritis for 6 days. The patient's peripheral white blood cell count was 18,600/µL and the C-reactive protein level was 2.44 mg/dL. A stool sample tested positive for rotavirus antigen...

BACKGROUND: The mortality of septicaemia, meningitis and encephalitis caused by Listeria monocytogenes is 20-40%. Twenty-one cases of invasive listeriosis associated with alemtuzumab, including at least 16 in patients with multiple sclerosis, have been published or reported to the World Health Organization Case Safety Reports Database. Three cases were fatal, including at least one patient treated for multiple sclerosis in 2016. CASE PRESENTATION: We report a patient with multiple sclerosis who developed pyrexia, nausea and abdominal discomfort few hours after the third and last infusion of her second alemtuzumab cycle...

A 62-year-old man developed a blood stream infection and meningitis due to Listeria monocytogenes, 20 days after an episode of pseudo-membranous colitis. The patient, hospitalized for the first time for transurethral prostatectomy, was readmitted 20 days later with watery diarrhea. Pseudo-membranous colitis was diagnosed and treated successfully, without testing for Clostridium difficile infection (CDI). After 15 more days, the patient developed again diarrhea, fever and confusion. Hospitalized again, blood and cerebrospinal fluid cultures resulted positive for L...

Listeriosis is a fatal infection for fetuses and newborns with two clinical main morbidities in the neonatal period, meningitis and diffused cutaneous lesions. In this study, we vaccinated pregnant females with two gold glyconanoparticles (GNP) loaded with two peptides, listeriolysin peptide 91-99 (LLO91-99) or glyceraldehyde-3-phosphate dehydrogenase 1-22 peptide (GAPDH1-22). Neonates born to vaccinated mothers were free of bacteria and healthy, while non-vaccinated mice presented clear brain affections and cutaneous diminishment of melanocytes...

Listeria monocytogenes is a well-known cause of meningitis in immunocompromised patients. This organism has a growing significance for community-acquired meningitis, which should have ampicillin added to the usual regimen. We describe a case of L. monocytogenes meningitis preceded by cholangitis. This case suggests gastrointestinal symptoms preceding meningitis may be a clue of listeriosis. It is important for physicians to consider L. monocytogenes as a cause of bacterial meningitis in patients with altered mental status preceded by gastrointestinal symptoms, especially in the immunocompromised population...

An abscess is defined as a collection of pus in various tissues of the body including skin and other organs. Abscesses most commonly are formed on the skin under the armpits, groin areas, and rectal areas. Most abscesses involve microbial infections with few remaining sterile. The treatment of abscesses includes both medical and surgical intervention. In the era of multidrug resistance, isolation and identification of the causative microbe and testing for antimicrobial susceptible patterns assume greater significance for the better management of patients, thereby reducing the resultant morbidity and mortality...

Infection with Listeria monocytogenes during pregnancy is associated with miscarriage, preterm birth, and neonatal complications, including sepsis and meningitis. While the risk of these conditions is thought to be greatest during the third trimester of pregnancy, the determinants of fetoplacental susceptibility to infection, the contribution of gestational age, and the in vivo progression of disease at the maternal-fetal interface are poorly understood. We developed a nonhuman primate model of listeriosis to better understand antecedents of adverse pregnancy outcomes in early pregnancy...

Listeria monocytogenes is a Gram-positive food-borne pathogen that in humans may traverse the intestinal, placental and blood/brain barriers, causing gastroenteritis, abortions and meningitis. Crossing of these barriers is dependent on the bacterial ability to enter host cells, and several L. monocytogenes surface and secreted virulence factors are known to facilitate entry and the intracellular lifecycle. The study of L. monocytogenes strains associated to human listeriosis epidemics has revealed the presence of novel virulence factors...

Cholesterol-dependent cytolysins (CDCs) are protein toxins that originate from Gram-positive bacteria and contribute substantially to their pathogenicity. CDCs bind membrane cholesterol and build prepores and lytic pores. Some effects of the toxins are observed in non-lytic concentrations. Two pathogens, Streptococcus pneumoniae and Listeria monocytogenes, cause fatal bacterial meningitis, and both produce toxins of the CDC family-pneumolysin and listeriolysin O, respectively. It has been demonstrated that pneumolysin produces dendritic varicosities (dendrite swellings) and dendritic spine collapse in the mouse neocortex, followed by synaptic loss and astrocyte cell shape remodeling without elevated cell death...

Listeria monocytogenes is an important cause of life-threatening bacteremia and meningoencephalitis in neonates, pregnant women, the elderly, and immunocompromised individuals. However, it is an uncommon cause of illness in immunocompetent children beyond the neonatal period. Ampicillin with or without an aminoglycoside remains the best treatment for listeriosis. Here, we report a rare case of Listeria meningitis and bacteremia in a 7-month-old immunocompetent girl, which was refractory to ampicillin plus gentamicin treatment and successfully treated by the addition of TMP/SMX...

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...
