Microorganisms such as Escherichiacoli and salmonella as well other organisms were affected by stress radiation, mechanical nutrient deprivation, high light stress, environmental and osmotic stress. Most of the enteropathogens to cause disease it was important for them to survive in an acid environment as inside the host, these organisms meet in the small intestine of inorganic acid (H+) in the stomach and a combination of inorganic and organic acids (volatile fatty acids). Here I review some pathogens such as E. Coli and salmonella, their mode of activity and survival against oxidative. https://www.biotech-asia.org/vol16no1/response-to-oxidative-stress-by-foodborne-pathogens/ Escherichia Coli; Genes; Oxidative Stress; Salmonella
