What is the life cycle of the shigella bacteria?

The life cycle of Shigella bacteria begins when it is ingested through contaminated food or water. Once in the intestines, it invades the epithelial cells of the intestinal lining, where it multiplies and spreads to adjacent cells. This invasion causes cell damage and inflammation, leading to symptoms such as diarrhea, fever, and abdominal pain. Shigella can also be excreted in feces, allowing it to spread to new hosts and continue the cycle.
