Antibiotics and MRSA
Staphylococcus aureus can cause infections in the skin, throat, and digestive tract. MRSA (methicillin-resistant Staphylococcus aureus) is a strain of staph bacteria that has developed resistance mechanisms to evade almost all current antibiotics. The bacteria is shown in full on the EM-scan on the left and in detail in the illustration.
The following bacterial sections are highlighted on the illustration with the biological processes targeted by some antibiotics listed:
Cell wall is the outer layer composed of a crosslinked network of peptidoglycan chains that protects the bacteria from osmotic pressure. Building of the cell wall is targeted by:
Membrane is filled with protein pumps and enzymes that build the cell wall
Cytoplasm is filled with DNA, ribosomes, enzymes, and other proteins key to bacterial life cycle. Cytoplasmic processes targeted by antibiotics:
