Staphylococcus aureus, often referred to as staph, is a very common bacteria. Approximately 25-30% of healthy people carry this organism on their skin or in their nose. 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.
They are often able to cure once-fatal diseases, such as the bacterial infection scarlet fever. Amoxicillin, penicillin, and erythromycin are common antibiotics that inhibit bacterial cell functions. Antibiotics are derived primarily from bacteria or fungi (mold), such as Penicillium.Antibiotics don't work exclusively against bacteria: some 'broad-spectrum' ones are also effective against protists.
