Abstract in English

Three hundreds and thirty samples of raw milk and some of the Syrian dairy products collected during 2002-2003 from different areas of Syria, and were used to detect the presecne of Listeria in these products. Results indicated that mainly L. monocytogenes and to a lesser degree L.innocua and L.ivanovii were found in these products. The perecentage of violating of the Syrian standards was 4 % in raw milk, 0.0% in pasteurized milk, 2% in white cheese, 0.5% in shinglish and 0.0% in ice cream. And it has been deterhmined the identity of the isolated bacterial species of Listeria from the above-mentioned products, where L. monocytogenes was dominant, and to a lesser estent were L. innocua and L. ivanovii.
