摘要: Listeria monocytogenes is the pathogen of listeriosis and it causes severe infections like septicemia, encephalitis, and meningitis, especially in immunocompromised individuals, newborns, and pregnant women.Its wide distribution in the environment and ability to survive or even grow under adverse conditions has made L.monocytogenes an important public health concern and in food industry[1].Many reports of invasive listeriosis were reported in developed countries in past[2], but outbreaks and sporadic listeriosis have been reported rarely in China, althouth L.monocytogenes has been isolated from almost all Chinese cities through Surveillance Network of Foodborne Diseases.
