Three listeria sp. were isolated from cerebrospinal fluid samples and their biochemical charaters were compared with the type strains; L m:na:ytogenes ATCCl5``313T, L monocytogenes ATCC19119T, L inncua ATCC33IDT, L grayi ATCC191WT L seeligeri ATCC35967T and L welshimeri ATCC35897T. The cellular fatty acid correosition and quinone profile of the isolates were investigated Also, the DNA G+C<mol%) contents were analyzed All the isolates were polar flagella regular rod-shaped bacteria The result of VI1EK GPI indicated that the isolates were listeria sp: In the result of antibiotic susceptibility test, all strains showed resistance to CIP, SM, and l\1OX The G+C content of DNA was ranged from 38.4% to 39.5% and MK-7 was found to be the major quinone in all the isolates. The major amino acid in the peptidoglycan layer of the isolated strains was meso- A2pm On the basis of the G+C contents, quinone profiles, amino acid analysis and biochemical characteristics, were identified as L monocytogenes
