What are symptoms of the bacterium Methicillin-resistant Staphylococcus aureus (MRSA)?
MRSA progresses substantially within 24–48 hours of initial topical symptoms. After 72 hours, MRSA can take hold in human tissues and become resistant to treatment. MRSA causes as many as 20% of Staphylococcus aureus infections in populations that use intravenous drugs. These out-of-hospital strains, or CA-MRSA, are more easily treated, though more virulent, than HA-MRSA. CA-MRSA apparently did not evolve de novo in the community but represents a hybrid between MRSA that spread from the hospital environment and strains that were once easily treatable in the community. Most of the hybrid strains also acquired a factor that increases their virulence, resulting in the development of deep-tissue infections from minor scrapes and cuts, as well as many cases of fatal pneumonia.
