Bye-Bye, Bacteria

摘要

Penicillin, the first antibiotic, became available for widespread use during World War II, treating wound and other infections and saving many lives. It was produced from a substance in fungus from the genus Penicillium, thus the antibiotic's name.rnAntibiotics affect the growth of bacteria but not of viruses, fungi, parasites, or other microbial agents. Antibiotics should not be taken for the flu because the flu is caused by a virus. Be certain you have a bacterial infection before taking antibiotics.
