Listeria monocytogenes is a pathogen frequently found in dairy products, and its growth is difficult to control. Bacteriocin-like inhibitory substances (BLIS), produced by lactic acid bacteria (LAB), having proven in vitro anti-Listeria activity, could provide an innovative approach to control L. monocytogenes; however, this application needs to be evaluated in vivo. In this study, twenty LAB s...

The aim of current studies was to validate the direct plating of a stool sample for Listeria monocytogenes detection, using selective medium Palcam agar with Palcam selective supplement. Validation was performed using stool samples collected from healthy humans inoculated with Listeria sp. strains. Stool samples were frozen to determine the influence of freezing on method robustness. The presen...

To study the interaction between cocultured Listeria monocytogenes and an antagonistic Leuconostoc strain producing an anti-Listeria bacteriocin, flow cytometry, a technique allowing on-line and real-time analysis, was used along with classical microbiological methods. Culture methods and flow cytometric measurements of the mixed culture over time point to a bactericidal action of the lactic ac...

Listeria monocytogenes is a Gram-positive, rod-shaped, non-spore-forming bacterium which is an important foodborne bacterial pathogen for humans worldwide with high mortality rates. Here, we report a 2,964,284-bp draft genome sequence of Listeria monocytogenes strain ATCC 7644 (American Type Culture Collection).

Investigation of Listeria monocytogenes transmission from environmental sources associated with pasture-raised chickens to poultry products is needed to determine ways to prevent potential foodborne illness. Here, we report the complete genome sequence of Listeria monocytogenes MR310, one of the isolates from a pastured-flock poultry management system.

background: listeria monocytogenes is one of the most important food-borne bacteria causing septicemia, meningitis and encephalitis in humans. the objective of this study was to evaluate the occurrence and antibiotic resistance of the bacterium in retail minced beef in ahvaz, south-west of iran. methods: in this survey, 150 samples of minced beef were randomly obtained from retail butcheries in...

endometritis as a risk factor for cystic ovarian disease, anoestrus and other reproductive disorder, is characterized by impact of dairy production performance and causes serious economic losses. listeria monocytogenes can cause endometritis. considering the importance of what mentioned present study was conducted to detection of l. monocytogenes in bovine endometritis from shahrekord, iran. al...

389 Abstract: Raw milk samples obtained from the Foundation of Milk Industry, three private dairy companies and individual dairy farms in Sivas, were tested for the presence of Listeria species. A total of 100 raw milk samples were analysed by Food and Drug Administration (FDA) and two-stage enrichment techniques. Two-stage enrichment procedure was found to be more effective than FDA method in ...

The peroxisomal proliferator-activated receptor γ (PPARγ) is a nuclear receptor that controls inflammation and immunity. Innate immune defense against bacterial infection appears to be compromised by PPARγ. The relevance of PPARγ in myeloid cells, that organize anti-bacterial immunity, for the outcome of immune responses against intracellular bacteria such as Listeria monocytogenes in vivo is u...

The virulence of Viable But Non-Culturable (VBNC) cells of 4 strains of Listeria monocytogenes was investigated in both a human adenocarcinoma cell line (HT-29) and a mouse model. LO 28, ATCC 19115 and CNL 895807 strains of Listeria monocytogenes became VBNC when incubated in microcosm water at 20 degrees C and Scott A strain at 4 degrees C. No culturable bacteria were detected in the VBNC stat...
