This article focuses on the many benefits of using antibiotics like penicillin for the treatment of an infection or illness. However, some scientists are alarmed that there are certain germs that have evolved and developed resistance to antibiotics. These drug-resistant germs are often called superbugs.

One or two bacteria are not a big problem, but the medical community fears that continued use of antibiotics would only cause more strains to become resistant.
