What's the difference between 'antibiotic' and 'antimicrobial'?

An antibiotic is a type of antimicrobial that specifically targets bacteria. 'Antimicrobial' is a broader term that also includes antivirals, antifungals, and antiparasitics.

Is 'antimicrobial' only an adjective?

No, it can be both an adjective ('antimicrobial properties') and a noun ('Prescribe a broad-spectrum antimicrobial').

Why is 'antimicrobial resistance' such a big concern?

It occurs when microbes evolve to survive exposure to antimicrobial drugs, making infections harder or impossible to treat, leading to higher mortality and healthcare costs.

Can I find antimicrobials in everyday products?

Yes, they are added to some soaps, cutting boards, textiles, and coatings with the intent of reducing microbial growth, though their public health benefit in such uses is debated by scientists.

Is “antimicrobial” formal?

Antimicrobial is usually technical/academic/medical in register.
