As well as for, you know, humanity in general.

The study, recently published in mBio, found that just one weeklong course of antibiotics changed participants’ gut microbiomes, with the effects sometimes lasting as long as a year. After all, antibiotics don’t discriminate—as they attack the bad bacteria, the good ones are vulnerable too.

In a randomized, placebo-controlled clinical trial at two centers (one in the United Kingdom, one in Sweden), researchers gave participants one of four commonly-prescribed antibiotics—clindamycin, ciprofloxacin, minocycline, and amoxicillin—or a placebo. They checked on participants’ oral and gut microbiomes by analyzing the bacteria present in their saliva and feces before the experiment (to get a baseline), right after the week of antibiotics, and one, two, four, and 12 months afterward.”
