Testing for Listeria is challenging because of its slow growth rate. Recently, we described a rapid Listeria culture isolation method. This method can be improved by utilizing a rapid molecular detection test such as the Assurance GDS tests for Listeria and Listeria monocytogenes. These two methods (culture isolation and Assurance GDS) use different enrichment strategies that may affect the num...
The study was carried out to determine the prevalence and the in-vitro pathogenicity of Listeria monocytogenes in sheep and goats reared by nomads of Jammu region of J&K, in addition to biochemical characterization of isolates. A total of 125 samples comprising of sheep and goat faecal samples and their rectal swabs were collected. Isolation of Listeria species involved the enrichment of the sa...
Listeria monocytogenes (commonly called Listeria) named for Joseph Lister. Listeria monocytogenes, is the bacterium that causes the infection listeriosis. It is a facultative anaerobic bacterium, capable of graving and reproducing inside the host’s cells, and is one of the most virulent food-borne pathogens of clinical infections resulting in death. Listeriosis is the leading cause of death amo...
introduction: different microbial compounds can induece maturation of dendritic cells (dcs) into dc1 or dc2 .in the present study, we used tumor antigen pulsed dendritic cell that matured with listeria monocytogenes antigen and cholera toxin (ct) in the treatment of a murin model of cancer. material and methods: tumor cells (wehi-164 balb/c derived fibrosarsoma) were injected subcutaneously to ...
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...
