INTRODUCTION: Listeria monocytogenes-related central nervous system infections may involve the cerebral parenchyma. Meningitis and meningoencephalitis are the most commonly seen forms and mainly affect immunocompromised patients; however, a less frequent form, rhombencephalitis, can occur in otherwise healthy people. Early treatment with appropriate antibiotic therapy is crucial for this otherwise fatal disorder. However, it is not always possible to rapidly establish the diagnosis because of varying presentations and discrepancies in diagnostic tests...

Catecholamine and serotonin are biogenic amines (BAs) that serve as neurotransmitters and play an important role in the regulation of cardinal functions that are mainly altered during central nervous system (CNS) infections. A total 92 samples of cerebrospinal fluid (CSF) were classified into 4 groups based on their etiology. In these samples, BAs/neurotransmitters i.e., dopamine (DA), 3,4-dihydroxyphenylacetic acid (DOPAC), homovanillic acid (HVA), and 5-hydroxyindoleacetic acid (5HIAA) were detected and quantified by high performance liquid chromatography with electrochemical detection (HPLC-EC) to determine the neurophysiology of the CNS infections by bacteria ( Listeria monocytogenes (Lm) and Neisseria meningitidis (Nm)) and herpes simplex virus (HSV)...

Listeria monocytogenes can cause circling disease, encephalitis, meningitis, septicemia, and mastitis in dairy cattle. Contamination from the environment can contaminate foods with Listeria spp. Consumption of foods containing L. monocytogenes can lead to listeriosis in susceptible people (adults with a compromised immune system), pregnant women, and infants. The objective of this study was to determine the prevalence of Listeria spp. and L. monocytogenes in various foods in Iran. We searched PubMed, Science direct, Scopus, Google scholar, and Iranian local databases including Iranian scientific information database and Magiran for relevant studies up to May 2015 using related keywords...

Listeria monocytogenes is a facultative intracellular bacterial pathogen that is frequently associated with food-borne infection. Of particular concern is the ability of L. monocytogenes to breach the blood-brain barrier, leading to life-threatening meningitis and encephalitis. The mechanisms used by bacterial pathogens to infect the brain are not fully understood. Here we show that L. monocytogenes is able to utilize vimentin for invasion of host cells. Vimentin is a type III intermediate filament protein within the cytosol but is also expressed on the host cell surface...

Listeria monocytogenes (LM) is an important food borne pathogen responsible for listeriosis. Further, LM is an etiological agent associated with life threatening conditions like meningitis and encephalitis. Biofilm forming and drug resistant LM may potentially become difficult to treat infections and hence effective controlling measures are required to prevent LM infections. In view of this, the present study evaluated an anti-listerial potential of edible brown seaweed, Eisenia bicyclis , by disc diffusion and micro-dilution methods...

All newborns superior to 34 weeks of gestationnal age (GA) are concerned by these guidelines of the French Society of Neonatology and the French Society of Pediatrics. Only newborns at risk of Early-Onset Neonatal Bacterial Infection who are clinically symptomatic have to be treated with probabilistic antibiotherapy treatment. The antibiotic combination of choice is amoxicillin + gentamicin. The two exceptions that justify dual therapy with Cefotaxime and Gentamicin are the bacteriological documentation of Escherichia coli and/or the presence of clinical signs of severity...

This case report describes a patient with scleroderma who developed Mycobacterium intracellulare infection, which for more than a year mimicked worsening of her connective tissue disorder. The patient was diagnosed with scleroderma based on puffy fingers that developed into sclerodactyly, abnormal nail fold capillaries, interstitial lung disease, Raynaud's phenomenon, esophageal dysmotility, and positivity for rheumatoid factor and anti-SSA antibodies. She developed massive inflammatory changes of the cutis, the subcutis, and the muscle fasciae of the right leg, that after several failed attempts of immunosuppressive treatments were found to be caused by Mycobacterium intracellulare ...

Listeria monocytogenes is a Gram-positive bacillus and facultative intracellular bacterium whose transmission occurs mainly through the consumption of contaminated food. Listeriosis has an incidence estimated at around three-six cases per million per year and the most common forms of the infection are neurolisteriosis, bacteraemia, and maternal-neonatal infection. Those affected by listeriosis are at the extremes age of the life or report specific risk factors, such as malignancies, causing a defect of cellular immunity...

A previously healthy 60-year-old patient presented to the emergency department with severe headache, altered personality and fever. He was treated for bacterial meningitis with delirium of unknown cause but presumed to be due to alcohol withdrawal. Despite receiving the antibiotic therapy regimen recommended for bacterial meningitis the patient's condition rapidly deteriorated with profound delirium and tachypnea. The intensivist who was consulted immediately suspected sepsis-associated organ failure and admitted the patient to the intensive care unit (ICU)...

An 80-year-old man, who had been diagnosed with ulcerative colitis, was admitted due to a fever and bloody diarrhea and was treated with a glucocorticoid and azathioprine. After 5 days, he developed an impaired consciousness, headache, and neck stiffness. A sample of the colonic mucosa, blood cultures, and cerebrospinal fluid revealed Listeria monocytogenes infection. Intravenous ampicillin improved the symptoms of fever, bloody diarrhea, and headache without any neurological sequelae. Physicians should consider that Listeria enteritis complicating ulcerative colitis can cause septicemia and meningitis in immunosuppressed patients...

Aneela Taj, Nusrat Jamil
Neuroinvasive microbes are capable of applying their influences on the autonomic nervous system (ANS) of the host followed by the involvement of central nervous system (CNS) by releasing extracellular metabolites that may cause alterations in the biochemical and neurophysiological environment. Consequently synaptic, neuroendocrine, peripheral immune, neuro-immune, and behavioural responses of the host facilitate the progression of infection. The present study was designed to extrapolate the effects of crude and purified extracellular peptides of neuropathogenic bacteria on behavioural responses and neurotransmission of Sprague Dawley (SD) models...

OBJECTIVES: Bacterial meningitis remains an important cause of morbidity and mortality worldwide. Its epidemiological characteristics, however, are changing due to new vaccines and secular trends. Conjugate vaccines against Haemophilus influenzae type b and Streptococcus pneumoniae (10-valent) were introduced in 1986 and 2010 in Finland. We assessed the disease burden and long-term trends of five common causes of bacterial meningitis in a population-based observational study. METHODS: A case was defined as isolation of S...

Listeria monocytogenes is a foodborne pathogen that causes septicemia, meningitis and chorioamnionitis and is associated with high mortality. Immunocompetent humans and animals, however, can tolerate high doses of L. monocytogenes without developing systemic disease. The intestinal microbiota provides colonization resistance against many orally acquired pathogens, and antibiotic-mediated depletion of the microbiota reduces host resistance to infection. Here we show that a diverse microbiota markedly reduces Listeria monocytogenes colonization of the gut lumen and prevents systemic dissemination...
