These antibiotics aren't made out of humans or in some way related to humans, but they have a place in human treatment plans. They're the ones we care about, and they're immensely valuable. Calling them "human antibiotics" is a reasonable shorthand for an article.

Their usage should be a lot more restricted than it currently is. Anything that unnecessarily diminishes their value to human treatment should be disallowed. Use on other species, for example; particularly when that enters the human food supply. Treating non-bacterial infections in humans is another.

I think it's pretty hard to overstate the importance of avoiding overuse of antibiotics. You don't even need to imagine modern medicine if antibiotics had never been discovered. More likely than not you wouldn't be alive today.
