listeria meningitis

Listeria monocytogenes (Lm) mainly infect pregnant women, children, the elderly, and other populations with low immunity causing septicemia and meningitis. Healthy people can tolerate higher doses of Lm and only cause gastrointestinal symptoms such as abdominal pain and diarrhea after infection. Compared to the above population, healthy people have a richer and more diverse gut microbiota. In this study, we show that the microbiota in the large intestine and the feces of mice can significantly inhibit the growth of Lm compared to the microbiota in the small intestine...

Listeria monocytogenes , is a Gram-positive facultative intracellular bacterium without spores. It can cause invasive diseases such as septicemia, meningitis, and encephalitis, and has a high mortality rate. This is a report on a recent case of neurolisteriosis isolated from cerebrospinal fluid sample of a patient with diabetes and chronic heart failure in our hospital. The patient initially received the combined treatment of cephalosporin and meropenem (both 1.0 g every 8 hours). We identified the pathogenic organism as L...

BACKGROUND: Listeriosis is a known cause of community acquired bacterial meningitis/meningoencephalitis. It occurs more frequently in neonates, older people and immunocompromised hosts. Rarely, brain abscesses can complicate the course of infection, which poses a difficulty in the management and elevates morbidity and mortality. Myasthenia gravis is an autoimmune disease that often requires immunosuppressive treatment, which increases the risk for invasive infections. CASE DESCRIPTION: A 75-year-old myasthenic patient, treated with prednisone and pyridostigmine, was diagnosed with invasive listeriosis...

Listeriosis is a rare infection among the general population, with an estimated incidence in Europe of 0.49 cases per 100,000 habitants in 2021. During pregnancy, the incidence rises around ten times, peaking in the third trimester. While maternal consequences are usually mild, the potential for severe fetal and neonatal outcomes exists, leading to fetal loss, prematurity, neonatal sepsis, meningitis, and mortality. In the newborn, the clinical presentation and outcomes are associated with both gestational timing of infection and birth gestational age...

Listerias of the phylogenetic lineage II (PLII) are common in the European environment and are hypovirulent. Despite this, they caused more than a third of the sporadic cases of listeriosis and multi-country foodborne outbreaks. L. monocytogenes ST37 is one of them. During the COVID-19 pandemic, ST37 appeared in clinical cases and ranked second in occurrence among food isolates in the Moscow region. The aim of this study was to describe the genomic features of ST37 isolates from different sources. All clinical cases of ST37 were in the cohort of male patients (age, 48-81 years) with meningitis-septicemia manifestation and COVID-19 or Influenza in the anamnesis...

In this case report, a previously healthy six-year-old presented with fever and altered mental status, and was found to have bacteremia with Listeria monocytogenes, acquired from premade fish balls. Invasive L. monocytogenes infection usually occurs in immunocompromised or newborns but may occasionally occur in healthy children with food-borne gastroenteritis. L. monocytogenes should be considered in patients with severe infection and symptoms of gastroenteritis, particularly since ceftriaxone, the Danish standard treatment for meningitis in children, does not cover L...

Listeria monocytogenes ( LM ) infections of the central nervous system are deadly and have vague symptoms. Traditional cerebro spinal fluid culture has a low positive rate, and because antibiotic use is common following therapy, it is more challenging to assess the response from pathogen content. In this case, a 66-year-old man who had a fever, a headache, and vomit was admitted to the hospital. He had diabetes, decline in thyroid function, and a history of pituitary tumor removal surgery. His initial treatment with ribavirin, ceftriaxone antibiotic, and moxifloxacin did not go well...

KEY CLINICAL MESSAGE: Listeria can cause neurological symptoms in immunocompromised and older patients. Additionally, it is impossible to rule out meningitis by the absence of typical meningeal irritation signs. Therefore, patients with fever and neurological impairments should be rapidly examined for blood and cerebrospinal fluid cultures to rule out Listeria meningitis. ABSTRACT: A woman in her 90s developed fever, dysarthria, and transient disturbance of consciousness...

BACKGROUND: Listeria monocytogenes meningoencephalitis (LMM) is a rare but dangerous infection of the nervous system. This study intends to summarize and discuss the clinical features, diagnostic methods, treatment, and outcomes. METHODS: LMM patients treated in the First Affiliated Hospital of Zhengzhou University from June 2013 to December 2022 were retrospectively studied. The clinical data, magnetic resonance imaging (MRI), biochemical and hematological parameters, pathogen tests, treatments, and outcomes information were collected and summarized...

Rapid identification of the causative pathogens of central nervous system infections is essential for providing appropriate management and improving patient outcomes. The performance of QIAstat-Dx Meningitis/Encephalitis (ME) Panel-a multiplex PCR testing platform-in detecting pathogens implicated in meningitis and/or encephalitis was evaluated using BioFire FilmArray ME Panel as a comparator method. This multicenter study analyzed 585 retrospective residual cerebrospinal fluid specimens and 367 contrived specimens...

Meningitis caused by Listeria monocytogenes is a rare disease in immunocompetent individuals, however, in the presence of certain risk factors with clinical signs indicating infection of the central nervous system it should not be ignored. In this case report, we present the medical history of a 72-year-old man, suffering from hypertension and liver cirrhosis, who was diagnosed with meningitis caused by L. monocytogenes. The patient was admitted to our Department with the symptoms of weakness, dizziness, high fever and urinary incontinence...

INTRODUCTION: The incidence of community-acquired acute bacterial meningitis has decreased during the last decades. However, outcome remains poor with a significant proportion of patients not surviving and up to 50% of survivors suffering from long-term sequelae. These guidelines were developed by the Deutsche Gesellschaft für Neurologie (DGN) under guidance of the Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften (AWMF) to guide physicians through diagnostics and treatment of adult patients with acute bacterial meningitis...

INTRODUCTION: Invasive listeriosis most often presents as bacteremia or neurolisteriosis. Cerebral infection mostly manifests as meningitis or meningoencephalitis, but cerebral abscesses are a rare manifestation. CASE PRESENTATION: We present the rare case of a 51-year old patient with progressive right sided hemiparesis caused by a cerebral abscess due to Listeria monocytogenes infection. The initially suspected cerebral ischemia or bleeding was ruled out. Magnetic resonance imaging led to the suspected diagnosis of an angiocentric lymphoma...

UNLABELLED: Listeria monocytogenes (Lm) is a food-borne pathogen associated with serious pregnancy complications, including miscarriage, stillbirth, preterm birth, neonatal sepsis, and meningitis. Although Lm infection within the gastrointestinal (GI) tract is well studied, little is known about the influence sex hormones may have on listeriosis. Estradiol (E2) and progesterone (P4) not only have receptors within the GI tract but are significantly increased during pregnancy. The presence of these hormones may play a role in susceptibility to listeriosis during pregnancy...

BACKGROUND: Although meningitis is largely preventable, it still causes hundreds of thousands of deaths globally each year. WHO set ambitious goals to reduce meningitis cases by 2030, and assessing trends in the global meningitis burden can help track progress and identify gaps in achieving these goals. Using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we aimed to assess incident cases and deaths due to acute infectious meningitis by aetiology and age from 1990 to 2019, for 204 countries and territories...

BACKGROUND: Secondary bacterial infection was initially rare in SARS-CoV-2 infectious disease (COVID-19) patients, but COVID-19-associated bacterial infectious diseases have recently been increasing. Furthermore, it might be difficult to distinguish COVID-19 from bacterial meningitis by the symptoms, and one might be uncertain about antibiotic therapy for Listeria meningitis infection-typically caused by eating contaminated food-in elderly persons and pregnant women. CASE REPORT: A 96-year-old woman who had been living alone was found to have SARS-CoV-2 infection in February 2023...

We report a case of fulminant fatal neonatal listeriosis due to horizontal transmission of Listeria monocytogenes (Lm) in a neonatal double room. Genomic analyses reveal a close genetic relationship between clinical isolates, supporting cross-contamination. Oral inoculation experiments in adult and neonatal mice show that neonates are susceptible to a low Lm inoculum and that this susceptibility results from the immaturity of the neonatal gut microbiota. Infected neonates should therefore be isolated for as long as they shed Lm in their feces to avoid horizontal transmission and its dire consequences...
