Listeria monocytogenes after Infection with T Cells δ / γ Responses in the Absence of Exaggerated Proinflammatory and Th1
Background: Listeria monocytogenes has been identified as a serious food-borne pathogen. There is concern that raw dairy products maybe source of listeria strains responsible for human listeriosis. The aim of this study was determination of listeria from daily products which transferred to laboratory of food stuffs in Lorestan. Materials and Methods: In this study 720 different dairy samples s...
BACKGROUND AND PURPOSE Encephalitis caused by Listeria monocytogenes (L. monocytogenes) is rare but sometimes fatal. Early diagnosis is difficult using routine cerebrospinal fluid (CSF) tests, while next-generation sequencing (NGS) is increasingly being used for the detection and characterization of pathogens. METHODS This study set up and applied unbiased NGS to detect L. monocytogenes in CS...
Many bacteria are known to inhibit food pathogens, such as Listeria monocytogenes, by secreting a variety of bactericidal and bacteriostatic substances. In sharp contrast, it is unknown whether yeast has an inhibitory potential for the growth of pathogenic bacteria in food. A total of 404 yeasts were screened for inhibitory activity against five Listeria monocytogenes strains. Three hundred and...
Mitochondria are essential and highly dynamic organelles, constantly undergoing fusion and fission. We analyzed mitochondrial dynamics during infection with the human bacterial pathogen Listeria monocytogenes and show that this infection profoundly alters mitochondrial dynamics by causing transient mitochondrial network fragmentation. Mitochondrial fragmentation is specific to pathogenic Lister...
Members of the genus Listeria are fastidious bacteria with respect to their nutritional requirements, and several minimal media described in the literature fail to support growth of all Listeria spp. Furthermore, strict limitation by a single nutrient, e.g., the carbon source, has not been demonstrated for any of the published minimal media. This is an important prerequisite for defined studies...
Background & Aims of the Study: Foodborne illnesses, resulting from consumption of contaminated foods, represent a substantial public health threat. Listeria monocytogenes is a foodborne pathogen bacteria and can cause serious problems in human. Because of this reason, Nowadays various compounds are being used to control these bacteria in foods. The aim of this study was to evaluate antilistari...
conclusions mlva analysis showed that samples obtained from different sources could have similar genetic profile. as a result, administration of penicillin in patients with listeriosis (especially pregnant women) and antibiotic susceptibility test are recommended. the fast and accurate methods such as mlva for tracking of pollution sources of l. monocytogenes are recommended during outbreaks. r...
A panel of hybridomas was produced using intact Listeria monocytogenes serotype 1/2a cells as the immunogen. An IgG2a monoclonal antibody (mAb) 'mAb2B3' was isolated that reacted with L. monocytogenes but not with a representative panel of related Listeria spp. and non-Listeria spp. Binding activity was greatest against L. monocytogenes serotype 1/2a and was significantly enhanced when cells we...
Listeria app, isolated from 13 of 129 (10%) corn silage samples, 21 of 76 (28%) hay silage samples, and 3 of 5 (60%) grass silage samples during a previous Vermont survey were subjected to automated ribotype (RT) analysis. The 13 positive corn silage samples contained 3 Listeria monocytogenes isolated (three RTs, including one known clinical RT) and 10 L. innocua isolates (four RTs). Similarly,...
