In order to effectively identify the Listeria.Standard Strains of several Listeria,including Listeria Monocytogenes,Listeria Monocytogenes,Listeria Monocytogenes,Listeria Monocytogenes,and Listeria Listeria,were selected and tested using the same detection method,during the process,the colony morphology,physiological and biochemical characteristics,hemolysis phenomenon were analyzed,and the characteristics of different strains were distinguished,so as to identify the target bacteria effectively and quickly.The results showed that staining microscopy,kinetic test and Catalase test were not effective in distinguishing Listeria,while biochemical identification and hemolytic test were effective.The comparison test among different standard strains can effectively identify the target bacteria.
