Abstract
Listeria monocytogenes are Gram-positive, facultatively anaerobic, non-spore-forming bacteria that easily adapt to changing environmental conditions. The ability to grow at a wide range of temperatures, pH, and salinity determines the presence of the pathogen in water, sewage, soil, decaying vegetation, and animal feed. L. monocytogenes is an etiological factor of listeriosis, especially dangerous for the elderly, pregnant women, and newborns. The major source of L. monocytogenes for humans is food, including fresh and smoked products. Its high prevalence in food is associated with bacterial adaptation to the food processing environment (FPE). Since the number of listeriosis cases has been progressively increasing an efficient eradication of the pathogen from the FPE is crucial. Understanding the mechanisms of bacterial adaptation to environmental stress will significantly contribute to developing novel, effective methods of controlling L. monocytogenes in the food industry.
Highlights
Listeria monocytogenes are Gram-positive, rod-shaped, non-spore-forming bacteria, widespread in the environment, i.e., water, soil, sewage, decaying vegetation, silage, and animals (O’Neil and Marquis, 2006; Gandhi and Chikindas, 2007)
We summarize the current knowledge about the adaptation of L. monocytogenes to stress factors in food processing plants
We know a lot about the stress response of L. monocytogenes, the pathogen is still present in the food processing environment (FPE) and is a threat to the consumer
Summary
Listeria monocytogenes are Gram-positive, rod-shaped, non-spore-forming bacteria, widespread in the environment, i.e., water, soil, sewage, decaying vegetation, silage, and animals (O’Neil and Marquis, 2006; Gandhi and Chikindas, 2007). ΣB helps L. monocytogenes survive under acid, osmotic, oxidative, and other stress conditions (Figure 2). The stress conditions encountered during food production and the adaptive response of L. monocytogenes affect the virulence of the bacilli and pose a much higher risk to consumers.
