Nonpathogenic bacteria are _____.

Nonpathogenic bacteria are _____.

• A. Harmless
• B. Toxic
• C. Harmful
• D. Deadly

Answer: (A)

Nonpathogenic means these bacteria do not cause disease in healthy individuals. They lack the traits that make organisms harmful, such as virulence factors and toxins, so they’re considered harmless under normal conditions. These bacteria can be present in the environment or on skin and, in many cases, are even useful in processes like fermentation or as probiotics. In short, they don’t produce illness, which is why they’re described as harmless.
