What is the primary effect of C. difficile?

It causes respiratory infections.
It releases toxins that destroy healthy gut cells.
It leads to urinary tract infections.
It causes skin infections.

The correct answer is: It releases toxins that destroy healthy gut cells.

The primary effect of C. difficile is related to its ability to release toxins that damage the cells in the intestines. This can lead to inflammation and, in severe cases, results in conditions such as antibiotic-associated colitis. The disruption of the gut flora and damage to intestinal cells by these toxins can lead to symptoms like diarrhea, abdominal pain, and more severe complications, including pseudomembranous colitis. Understanding C. difficile's mechanism is crucial for recognizing the importance of maintaining gut health and preventing antibiotic overuse, which can predispose individuals to C. difficile infections. The connection between the release of toxins and the gut's health status is essential for healthcare professionals when diagnosing and treating this infection.
