{{MRSA background}}

==Management==
*[[Antibiotics]]
**[[Cephalexin]] + [[Bactrim DS]]
***Estimated 95-100% sensitivity of CA-MRSA
**[[Clindamycin]] 
***Approximately 50% sensitivity to CA-MRSA
***Inducible resistance by erythromycin in laboratory, unclear significance
**[[Doxycycline]]
***Contraindicated in pregnant females and children due to deposition in teeth and bones
**[[Vancomycin]] IV if severe infection/sepsis 
**[[Linezolid]]
***Indicated in severe soft tissue infections and pneumonia thought to be caused by [[CA-MRSA]] or HA-[[MRSA]]
**[[I&D]] + [[Bactrim DS]] if [[abscess]]
