Compress a dense paragraph into one sentence

The prompt

Antibiotics are a type of medication used to treat bacterial infections. They work by either killing the bacteria or preventing them from reproducing, allowing the body's immune system to fight off the infection. Antibiotics are usually taken orally in the form of pills, capsules, or liquid solutions, or sometimes administered intravenously. They are not effective against viral infections, and using them inappropriately can lead to antibiotic resistance.

Explain the above in one sentence:

Expected result

A single clear sentence compressing the paragraph's core claims (what antibiotics are, how they work, and their limits) without losing the key caveats.

Why it works

A minimal template for concept explanation: paste any dense paragraph, then constrain the output length explicitly ("in one sentence") instead of just asking to "summarize", which tends to produce vaguer, longer results.
