A 10-year-old boy visits his pediatrician with a 5-day history of fever, sore throat with pus-filled abscesses, and rash. Initial symptoms included sore throat, chills, and a low-grade fever (100.5°F ). The sore throat progressively worsened, with rapid development of a red, sunburn-like rash that felt like sandpaper spreading from the axilla to the torso. Development of this rash coincided with abrupt onset of fever (up to 103.5°F ), headache, and strawberry-like tongue. Bacteria were cultured from a throat swab on blood agar and a gram stain was performed. Beta-hemolysis was present on the blood agar plate and gram staining revealed the presence of gram positive cocci in chains. A. What disease does this patient have? B. Name the bacterium (genus and species) that caused her condition. C. Explain your reasoning. D. List the toxin associated with the development of the rash. E. List two other infections this bacterium causes.
