Salmonella possesses several special features that contribute to its pathogenicity. It is a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments. Its ability to invade intestinal epithelial cells is aided by specialized structures called type III secretion systems, which inject virulence factors directly into host cells. Additionally, Salmonella can survive in harsh conditions, including low pH and high salt concentrations, enhancing its potential to contaminate food sources and cause infection.
