Which statement best describes Campylobacter growth in the environment?

• A. It readily grows in standard household environments.
• B. It has complex nutritional requirements limiting environmental growth.
• C. It forms endospores enabling tough survival.
• D. It thrives in high-salt foods.

Answer: (B)

Campylobacter is a fastidious, microaerophilic bacterium, meaning it needs a very specific mix of gases and nutrients to grow. In the environment, those precise conditions are hard to come by, so its growth is limited rather than robust. It doesn’t form spores, and it’s sensitive to drying and to high salt, which further curtails survival outside a host. Because of these constraints, it won’t readily multiply in standard household environments or in high-salt foods. The statement that best describes this is that its growth in the environment is limited by its complex nutritional requirements, which require conditions not commonly found outside specific hosts or controlled settings.
