Stress survival islets contribute to clonal and serotype-specific differences in L. monocytogenes

Abstract Listeria monocytogenes is an important opportunistic foodborne pathogen causing listeriosis, often fatal infection leading to meningitis, sepsis, or of the fetus and abortion in susceptible individuals. Diverse ready-to-eat food (RTE) like dairy, meat, fish, vegetables, complex foods are linked with listeriosis outbreaks. L. capable surviving stressful environmental conditions grow refrigerated foods. Regarding stress-related genes, SSI-1 contributes survival cells under suboptimal conditions, such as high salt content acidic environment. At same time, SSI-2 responsible for persistence alkaline oxidative stresses.
