Abstract
L. monocytogenes is recognized as a food borne pathogen of maJOr significance responsible for gastroenteritis and more severe manifestation including septicemia, encephalitis, abortion and may end with death.
The implication of variety of food product mostly of dairy and meat origin in outbreaks and sporadic cases increasing occurrence in the last 20 years of listeriosis outbreaks associated with the consumption of contaminated food with L. monocytogenes so it is considered as one of the most important food pathogen.
So the present study aimed to characterize L. monocytogenes
isolated from different food origin.
A total of 79 Listeria species isolated from 650 samples of different foods (500 dairy products, 50 minced meat and beef burger, 50 chicken fillet, and 50 seafood).
In this investigation, the recovery rate of Listeria from examined samples was 12.1%. From 79 Listeria isolates 25 isolates (3.8%) were identified as L. monocytogenes isolated from sea food, chicken fillet, meat and meat products and dairy products with incidence of 12%, 8%,
4% and 2.6% respectively.
14 selected L. monocytogenes isolates (5 from dairy products, 5 from sea food, 2 from meat and 2 from chicken fillet) and reference strain were characterized serologically (4 isolates belonging to serotype (I), 8 isolates belonging to serotype (4) and 3 isolates
. (were untyped by the available antisera
