Final answer:
MRSA is a dangerous strain of Staphylococcus aureus that is resistant to antibiotics. It can transfer resistance to other bacteria, be difficult to treat, and potentially acquire additional resistance genes.
Step-by-step explanation:
Methicillin-Resistant Staphylococcus aureus (MRSA) is a dangerous strain of Staphylococcus aureus that is resistant to antibiotics. It was first detected in 1961 and has since become a serious infectious disease. MRSA infections can be particularly concerning because they can transfer methicillin-resistance to other bacteria, patients may not be treated with the correct antibiotics rapidly enough to prevent serious illness, and MRSA has the potential to acquire additional antibiotic resistance genes to become a "superbug."
