Bacteria have been around for a long, long time, much longer than humans have been. In fact, they are the oldest life form on earth. They raise special concerns to scientists due to the fact that they can cause disease and also mutate to resist medicines. Plasmids pass DNA to one another changing the bacteria’s structure, and making each bacterium very individualistic. These resisting strands that are popping up are sometimes untreatable by our antibiotics,

Bacteria
Bacteria are often maligned as the causes of human and animal disease (like this one, Leptospira, which causes serious disease in livestock).
