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 ...

Ag-presenting dendritic cells (DCs) must survive bacterial infection to present Ag information to naive T cells. The greater ability of DCs' host defense is evident from the report that DCs are more resistant to Listeria monocytogenes than macrophages. However, the molecular mechanism of this resistance is unclear. We found that Listeria replicate more slowly in wild-type DCs compared with fasc...

The iap gene encodes the protein p60, which is common to all Listeria species. A previous comparison of the DNA sequences indicated conserved and species-specific gene portions. Based on these comparisons, a combination consisting of only five different primers that allows the specific detection and differentiation of Listeria species with a single multiplex PCR and subsequent gel analysis was ...

Dobeic M., Kenda E., Mičunovič J., Zdovc I. (2011): Airborne Listeria spp. in the red meat processing industry. Czech J. Food Sci., 29: 441–447. The aim of this study was to determine the potential presence of the airborne Listeria spp. and its correlation with the aerobic mesophilic bacteria and Listeria carcass contamination in three red meat slaughtering and three processing plants. Airborne...

objective: listeria monocytogenes is a facultative, gram-positive bacterium which is found in soil, water, decaying vegetables, raw milk, and contaminated dairies. listeria monocytogenes causes listeriosis. listeriosis is a zoonosis disease, which transfers from animals to humans by animal feces and contaminated dairies. listeriosis causes the flu like disease or self-limited enteritis, but it ...

The risk of pathogen contamination and growth is one of the main safety concerns associated with fresh-cut produce, as highlighted by the increasing number of produce-linked foodborne outbreaks in recent years. The pathogens of major concern in freshcut produce are Listeria monocytogenes, pathogenic Escherichia coli, and Salmonella spp. Listeria monocytogenes is able to grow and multiply in veg...

Phosphatidylinositol-specific phospholipases (PI-PLCs) are virulence factors produced by many pathogenic bacteria, including Bacillus anthracis and Listeria monocytogenes. Bacillus PI-PLC differs from Listeria PI-PLC in that it has strong activity for cleaving GPI-anchored proteins. Treatment of murine DCs with Bacillus, but not Listeria, PI-PLC inhibited dendritic cell (DC) activation by TLR l...

BACKGROUND Listeria monocytogenes is a rare cause of endogenous endophthalmitis. In the limited number of reported Listeria endophthalmitis cases, visual acuity outcomes have been very poor. FINDINGS Here, we report a case of Listeria endophthalmitis that was complicated by recurrent inflammation. The patient required treatment with both intravitreal and long-term systemic antibiotics. An ant...

Samples were taken from 100 camel sausages from the different retail markets in Aydin province in the south-west of Turkey and they were tested for the presence of Listeria spp by biochemical methods. Samples were enriched using Listeria Enrichment Broth and they were inoculated onto Listeria Selective Agar. Listeria monocytogenes was isolated from nine samples (9%), Listeria innocua from 14 sa...
