Antibiotic resistance

• Bacteria can mutate so they are not killed by antibiotics
• When an infection is treated with antibioitics, non-resistant cells are killed while resistant bacteria survive

  The resistant bacteria will continue to multiply and the population of the resistant bacteria will increase
• Resistant strains could cause a serious infection that cannot be treated with antibiotics
• It is important to finish a whole course of antibiotics so resistant strains don't develop / survive
• MRSA is a strain of antibiotic-resistant bacteria.
