Which of the following is NOT TRUE about Campylobacter jejuni?
**Core Concept**
Campylobacter jejuni is a Gram-negative, spiral-shaped bacterium that is a leading cause of bacterial gastroenteritis worldwide. It is primarily transmitted through the consumption of contaminated food and water, as well as by handling raw poultry and other undercooked meats.
**Why the Correct Answer is Right**
Campylobacter jejuni is a zoonotic pathogen, meaning it can be transmitted between animals and humans. Infection with C. jejuni typically presents with diarrhea, abdominal cramps, and fever, and can lead to Guillain-Barré syndrome, a rare autoimmune disorder. The bacterium has a unique ability to survive outside of a host, making it a hardy pathogen that can persist in the environment.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because C. jejuni is a common cause of foodborne illness, and outbreaks have been linked to contaminated poultry, produce, and dairy products.
**Option B:** Incorrect because C. jejuni is a leading cause of bacterial gastroenteritis, and its symptoms are well-documented.
**Option C:** Incorrect because C. jejuni has been linked to the development of Guillain-Barré syndrome, a rare autoimmune disorder.
**Clinical Pearl / High-Yield Fact**
C. jejuni is often misdiagnosed as other gastrointestinal pathogens, such as Salmonella or Shigella. However, its unique ability to survive outside of a host and its association with Guillain-Barré syndrome make it a distinct clinical entity.
**Correct Answer:** None of the above
