Clinical cases of neonatal listeriosis are associated with brain disease and fetal loss due to complications in early or late pregnancy, which suggests that microglial function is altered. This is believed to be the first study to link microglial apoptosis with neonatal listeriosis and listeriosis-associated brain disease, and to propose a new nanovaccine formulation that reverses all effects of listeriosis and confers Listeria monocytogenes (LM)-specific immunity. We examined clinical cases of neonatal listeriosis in 2013-2015 and defined two useful prognostic immune biomarkers to design listeriosis vaccines: high anti-GAPDH1-22 titres and tumor necrosis factor (TNF)/interleukin (IL)-6 ratios...

Fever may be the only sign of a serious bacterial infection (SBI) in neonates. Ampicillin plus cefotaxime (A+C) and ampicillin plus gentamicin (A+G) are commonly used as empiric therapies for Escherichia coli, Group B Streptococcus (GBS) and Listeria monocytogenes, which are the most likely neonatal SBI pathogens (1). Culture-based screening and prophylaxis has significantly lowered GBS infections and an alarming increase in the antimicrobial resistance rates of Gram-negative bacteria, including cefotaxime and gentamicin resistance, has been reported (1-3)...

Listeriosis is a disease of humans and domestic mammals (mainly ruminants) with variable manifestations, primarily encephalitis, septicemia, and abortion. Although Listeria monocytogenes readily causes illness in ruminants, the prevalence among domestic South American camelids (llamas and alpacas) is low and has not been documented in their wild counterparts, the vicuna and guanaco. We describe herein the clinical signs, autopsy findings, and histopathology of septicemia and suppurative meningoencephalitis caused by L...

The Gram-positive facultative intracellular bacterium Listeria monocytogenes is the causative agent of listeriosis, a severe food-borne infection. Pregnant women are at risk of contracting listeriosis, which can potentially lead to miscarriage, stillbirth, preterm birth, and congenital neonatal infections. While other systemic bacterial infections may result in adverse pregnancy outcomes at comparable frequencies, L. monocytogenes has particular notoriety because fetal complications largely occur in the absence of overt illness in the mother, delaying medical intervention...

PURPOSE: Listeriosis is a rare foodborne illness caused by Listeria monocytogenes. It can be transmitted by consuming contaminated ready-to-eat food, long shelf-life products, deli meats, and soft cheeses. Listeria has a predilection to affect immunocompromised patients, elderly people, pregnant women and neonates. In particular, pregnant women are at ~18 times greater risk of infection than general population due to specific pregnancy-related suppressed cell-mediated immunity and placental tropism of L...

AIM: Streptococcus pneumoniae (S. pneumoniae) is sometimes implicated in neonatal bacterial meningitis. This study described the demographic, clinical and biological features of neonatal S. pneumoniae meningitis and compared pneumococcal and group B streptococcal (GBS) neonatal meningitis. METHODS: We conducted a case-control study that compared neonates, aged one to 28 days with S. pneumoniae meningitis or GBS meningitis. Each case with S. pneumoniae was randomly matched to four control patients with GBS by age group and study year...

The bacterial pathogen Listeria monocytogenes causes foodborne systemic disease in pregnant women, which can lead to preterm labor, stillbirth, or severe neonatal disease. Colonization of the maternal decidua appears to be an initial step in the maternal component of the disease as well as bacterial transmission to the placenta and fetus. Host-pathogen interactions in the decidua during this early stage of infection remain poorly understood. Here, we assessed the dynamics of L. monocytogenes infection in primary human decidual organ cultures and in the murine decidua in vivo A high inoculum was necessary to infect both human and mouse deciduas, and the data support the existence of a barrier to initial colonization of the murine decidua...

We conducted a retrospective review of electronic medical records of all cases of bacterial meningitis in neonates and young infants at our institution from 2004 to 2014. Fifty-six cases were identified. The most common causative organism was group B streptococcus, followed by Escherichia coli and then Listeria monocytogenes. Forty-four of the 56 patients in the study had abnormalities of the blood white blood cell (WBC) count. The most common WBC count abnormalities were leukopenia and elevation of the immature to total (I:T) neutrophil ratio...

OBJECTIVES: Listeria monocytogenes can cause sepsis and meningitis. We report national surveillance data on L. monocytogenes meningitis in the Netherlands, describing incidence changes, genetic epidemiology and fatality rate. METHODS: We analyzed data from the Netherlands Reference Laboratory of Bacterial Meningitis for cases of L. monocytogenes meningitis. Strains were assessed by serotyping and bacterial population structure by multi-locus sequence typing. RESULTS: A total of 375 cases of Listeria meningitis were identified between 1985 and 2014...

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...

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...

BACKGROUND: Listeriosis is a severe foodborne infection and a notifiable disease in France. We did a nationwide prospective study to characterise its clinical features and prognostic factors. METHODS: MONALISA was a national prospective observational cohort study. We enrolled eligible cases declared to the National Reference Center for Listeria (all microbiologically proven) between Nov 3, 2009, and July 31, 2013, in the context of mandatory reporting. The outcomes were analysis of clinical features, characterisation of Listeria isolates, and determination of predictors of 3-month mortality or persisting impairment using logistic regression...

BACKGROUND: Early onset sepsis (EOS) is a major cause of morbidity and mortality in preterm infants, yet diagnosis remains inadequate resulting in missed cases or prolonged empiric antibiotics with adverse consequences. Evaluation of acute phase reactant (APR) biomarkers in umbilical cord blood at birth may improve EOS detection in preterm infants with intrauterine infection. METHODS: In this nested case-control study, infants (29.7 weeks gestation, IQR: 27.7-32...

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...

BACKGROUND: Coagulase negative staphylococci (CoNS) and Listeria monocytogenes have important roles in pathogenesis of various genital tract infections and fatal foetomaternal infections, respectively. The aim of our study was to investigate the inhibitory effects of two novel bacteriocins on biofilms of CoNS and L. monocytogenes genital isolates. METHODS: The effects of licheniocin 50.2 from Bacillus licheniformis VPS50.2 and crude extract of bacteriocins produced by Lactococcus lactis subsp...
