Sometimes, staph causes an infection.
Bacteria can often be killed by antibiotics because the cell wall on the outside is destroyed, expelling the DNA out of the body of the pathogen, therefore making the pathogen incapable of producing proteins and dies. Bacteria typically range between 1 and 5 micrometers in length.
Antibiotics kill bacteria, not archaea, fungi, or protists. The discovery of the antibiotic penicillin in the 1920s made a big impact on human history. Not only did it lead to a cure for bacterial infections that were once deadly, but it also led a big interest in finding new antibiotics.he discovery of the antibiotic penicillin in the 1920s made a big impact on human history.
