What does C Difficile primarily cause?

Respiratory infections
Watery diarrhea
Skin infections
Urinary tract infections

The correct answer is: Watery diarrhea

C. Difficile, also known as Clostridioides difficile, primarily causes watery diarrhea. This bacterium is significant in healthcare settings, especially after the use of antibiotics, as it disrupts the normal gut flora. When the balance of bacteria in the intestines is disturbed, C. difficile can proliferate and produce toxins that lead to inflammation of the colon, resulting in diarrhea that can become severe. While it can cause more serious conditions, including colitis, the hallmark symptom is diarrhea that is often watery and can be accompanied by abdominal pain or cramps. The other options listed are associated with different pathogens or conditions. Respiratory infections are typically caused by viruses or bacteria that target the respiratory system. Skin infections are usually the result of other organisms such as bacteria like Staphylococcus or Streptococcus. Urinary tract infections are most commonly caused by bacteria such as Escherichia coli.
