What exactly are antibiotics?

Or rather, what’s a definition of antibiotics that excludes all non-antibiotics while including all antibiotics?

Some sources say that anything that kills bacteria or stops bacteria from growing is an antibiotic. By that logic, though, bleach is an antibiotic, and I don’t think that’s right.

Based on my research, one definition I would throw out there is “substance that kills bacteria while doing minimal damage to the host”— but bacteriophages do that, and they’re definitely not antibiotics.

I know there’s generally a fungal connection, but I don’t think that can serve as demarcation— modern penicillin is synthetic, and others are fully synthetic, I believe.

So how would you define antibiotics?

The definition of antibiotic is a drug we use to treat bacterial infections. So anything that kills bacteria COULD be an antibiotic if it were prescribed by a doctor for that purpose… but since doctors like their patients, y’know, *alive,* they tend to avoid prescribing things like bleach, and they instead stick to ones that have been demonstrated to have minimal side effects.
