MDROs are defined as microorganisms resistant to

• A. One or more antimicrobial agents
• B. A single antibiotic
• C. Vaccines
• D. Antivirals

Answer: (A)

Multi-drug resistant organisms are microbes that survive exposure to antimicrobial drugs, making infections harder to treat. Among the options, the statement that they are resistant to one or more antimicrobial agents best captures this concept, since it emphasizes resistance to drugs used to treat infections. The other choices don’t fit: vaccines are not antimicrobial drugs, antivirals target viruses, and being resistant to a single antibiotic doesn’t convey the broader resistance implied by the term multidrug-resistant. Understanding this helps guide infection prevention and careful antibiotic use to limit spread and treatment challenges.
