Which bacterium produces a toxin that leads to watery diarrhea?

The bacterium that produces a toxin leading to watery diarrhea is Clostridioides difficile, commonly referred to as C. Diff. This organism is known for causing significant gastrointestinal issues, particularly in individuals who have recently received antibiotics, as these medications can disrupt the balance of normal gut flora. C. Diff produces toxins that damage the intestinal lining, which results in inflammation and diarrhea.

Infections with C. Diff often manifest as severe diarrhea that can be profuse and watery, alongside abdominal pain and cramping. The particular toxins produced by C. Diff can lead to more serious conditions, such as colitis, which can require hospitalization and intensive treatment.

While other bacteria listed can cause gastrointestinal symptoms, the specific toxins produced by C. Diff are directly associated with the characteristic watery diarrhea that defines this infection. This understanding is critical for both recognizing symptoms and managing appropriate treatment for patients affected by this pathogen.
