Since that time, scientists have found that numerous species of fungi 1 produce chemicals to destroy bacteria and that bacteria even produce chemicals that destroy other bacteria. Antibiotics 2 are relatively 3 new in modern medicine, but the earliest medical records from China, Egypt, and Mesopotamia show that people have used moldy 4 and fermented 5 substances to treat wounds for over three thousand years. The ability to produce these chemical toxins 6 may have evolved in bacteria as a survival tactic 7. Today we use those same chemicals in our own struggle against bacteria.
