Understanding Salmonella: A Guide to its 10 Symptoms

4. Diarrhea

Salmonella bacteria infect and kill epithelium cells that line the inner surface of the intestines. The dead and damaged cells cause inflammation in the intestines and disturb the normal, healthy bacteria in the intestinal tract. This damage triggers diarrhea that may contain mucus or blood. This process is part of the bacterium's life cycle. The body expels Salmonella bacterium along with loose and watery stools. It is essential to practice good hygiene when infected, as the bacteria in contaminated stool can infect other people or animals.
