Antibiotics kill bacteria in a bunch of different ways. One of those ways is by stopping them producing folates.

Folates are an essential part of DNA production, so without them bacteria can’t replicate.

Unfortunately, humans need folates, too. We get them from our food. These bacteria have developed a way to take folates from their environment like we do, rather than making them in-house.

It’s like if someone was building a shelter and you broke their roof, so they just leaned over and grabbed the roof off your shelter to cover them instead.

I like that explanation, too, among others here- stole the materials from my roof makes sense to me
