Micro in the Clinic Scraped Knee and Loss of a Leg? Arjun is an active 15-year-old high school student; he plays soccer, runs track, and volunteers at his local food bank every week. A couple of days ago, while skateboarding, he scraped his knee pretty badly. He didnât tell his mom because he knew that she would lecture him about being careful, and he was worried that she wouldnât let him go back to the skate park. He washed his knee with soap and water well when he got home and didnât think more about it. The next morning, Arjunâs knee is stiff, swollen, and quite red. He washes it again when he takes a shower, and then he heads to school. Later in the afternoon, Arjun realizes that his knee is really sore, and he feels hot. He shows up for soccer practice, but his coach tells him that because he has a fever, he should go home and have his mom take him to the doctor to look at his knee. The doctor examines Arjunâs knee and tells him that the wound is infected. The doctor is concerned by the rapid progression of the infection and Arjunâs fever. He admits Arjun to the hospital and orders an intravenous course of antibiotics. After two days of treatment, his knee actually looks worse; the infection is spreading to surrounding tissues. Arjunâs mom is very worried and anxious for the doctor to visit in the afternoon. 1.What do you think? Is there cause for Arjunâs mom to be worried? 2.What potential virulence factors may be associated with the microbes causing Arjunâs infection? Specifically what types of microbe (Gram + or Gram -) leads to fever? 3.Could there be any potential complications arising from infection with these microbes? Please explain.
