A young woman notices a red bruiselike lesion that looks like a target on her lower leg. She cannot remember getting bruised, even though she went hiking through the woods last weekend. The bruise goes away in about a week and she thinks nothing more about it. About 2 weeks later, she develops joint and bone pain, extreme fatigue, and her heart just "doesn't feel right." What disease does she have, and what antimicrobial agent is used to treat it?
