Which term describes harmless microorganisms with useful functions?

Which term describes harmless microorganisms with useful functions?

• A. AIDS
• B. Nonpathogenic
• C. HIV
• D. Contamination

Answer: (B)

Harmless microorganisms with useful functions are described as nonpathogenic. Nonpathogenic organisms do not cause disease in healthy individuals and can contribute to beneficial processes on the skin or in the environment, such as protecting against harmful microbes or supporting balanced microbial communities. AIDS and HIV refer to disease states caused by a virus, not a descriptor of microbes with helpful roles. Contamination describes the introduction of unwanted microbes or substances, which is the opposite of a beneficial, nonpathogenic function. So, nonpathogenic is the correct term.
