What dose Campylobacter do to invade the body?

Campylobacter invades the body primarily through contaminated food or water, often leading to gastrointestinal infections. Once ingested, the bacteria adhere to and penetrate the intestinal epithelial cells, evading the host's immune response. They can induce inflammation and disrupt normal gut function, resulting in symptoms like diarrhea, abdominal pain, and fever. Additionally, Campylobacter can spread through the bloodstream in severe cases, potentially leading to systemic infection.
