Question: What is the dirtyest bacteria you have ever found???

I’m not sure if I used particularly dirty bacteria (although some of the bacteria I have used are mostly found in the soil). The bacteria I use instead are quite toxic and they release molecules that can damage the cells in your body.

The dirtiest things I have found in my research are things called bacteriophage. They are predators of bacteria and kill them by injecting themselves inside them. They are found anywhere bacteria are – and where bacteria are are in dirty places like rivers and drains.
