1. Introduction
Listeria monocytogenes is an intracellular pathogen that can cause obtrusive disease in Homo sapiens and other animals. 1 Most Listeria infections are sub clinical they may go unnoticed. However, in some cases, a listeria infection can lead to life-threatening complications such as septicemia and meningitis. Foodborne diseases cause approximately 76 million illnesses, 325,000 hospitalizations, and 5000 deaths in all over the world each year. 2Listeria infections are caused by eating food contaminated with the bacteria L. monocytogenes, which can also be found in water, soil etc. Humans are often afflicted to listeria by consuming: Unpasteurized milk or foods made with unpasteurized milk, soft cheeses, hot dogs and deli meats that have been contaminated after processing, raw vegetables that have been contaminated from the soil or from contaminated manure used as fertilizer and infected animal meat etc. 3 Therefore the present study describes the isolation of two novel strains of L. monocytogenes from retail chicken, beef meat and seafood samples.
