introduction: listeria monocytogenes is a gram positive bacteria, frequently found in the environment and is responsible for food-borne disease such as perinatal infections, septicameia and meningeonceohalitis in human and animals. material and methods: for this reason, distribution of the ctpa determinate among l. monocytogenes isolated from clinical environment, diry and poultry samples were ...
The suitability of seven media for the enumeration of Listeria spp. was evaluated at 30 degrees C for 48 h. The media tested were (i) the original McBride Listeria agar formulation (with glycine); (ii) modified McBride agar containing glycine anhydride; (iii) LiCl-phenylethanol-moxalactam (LPM) agar; (iv) acriflavine-ceftazidime agar; (v) Rodriguez isolation agar (RISA); (vi) modified Vogel-Joh...
CD8(+) T cells are required for protective immunity against intracellular pathogens such as Listeria monocytogenes. In this study, we used class Ia MHC-deficient mice, which have a severe reduction in circulating CD8(+) T cells, to determine the protective capacity of class Ib MHC-restricted T cells during L. monocytogenes infection. The K(b-/-)D(b-/-) mutation was backcrossed onto a C.B10 (BAL...
BACKGROUND Despite a decreasing incidence of listeriosis in the United States, molecular subtyping has increased the number of recognized outbreaks. In September 2000, the New York City Department of Health identified a cluster of infections caused by Listeria monocytogenes isolates with identical molecular subtypes by pulsed-field gel electrophoresis (PFGE) and ribotyping. METHODS To determi...
Background and purpose: Listeria monocytogenes is a foodborne pathogen and a pothential risk to public health. Listeriosis is one of the most serious infectious diseases in most developed countries. Consumption of raw milk and unpasteurized traditional dairy products such as cheese can be a major reason for listeriosis in humans. This reaserch aimed at investigating Listeria monocytogenes conta...

Listeria monocytogenes is a pathogen associated with meningitis in the immunosuppressed patient. The pathogen is usually found in soft cheeses and raw milk. We present a case of an infected popliteal artery stent graft with Listeria monocytogenes. The report focuses on the diagnosis and treatment with surgical explantation and vascular reconstruction.
In this study, 468 Listeria strains were checked for the presence of phosphatidylinositol-specific phospholipase C (PI-PLC) activity by using a simple assay that consisted of overlaying colonies formed on agar plates with L-alpha-phosphatidylinositol as substrate. In this assay, PI-PLC-active colonies show turbid halos around the colonies as a result of the release of insoluble diacylglycerol f...
A total of 336 Listeria isolates from ready-to-eat (RTE) meat products and meat-processing environments, consisting of 206 Listeria monocytogenes, and 130 Listeria innocua isolates, were characterized by disc diffusion assay and minimum inhibitory concentration (MIC) values for antimicrobial susceptibility against twenty antimicrobials. Resistance to one or two antimicrobials was observed in 71...
PURPOSE Rapid development of nanotechnology has recently brought significant attention to the extraordinary biological features of nanomaterials. The objective of the present investigation was to evaluate morphological characteristics of the assembles of gold and platinum nanoparticles (nano-Au and nano-Pt respectively), with Salmonella Enteritidis (Gram-negative) and Listeria monocytogenes (Gr...
