Quizplus · Accepted Answer

The presence of gram-positive cocci arranged in grapelike clusters and the large, creamy colonies with areas of hemolysis on blood agar suggests Staphylococcus aureus as the causative agent. Streptococcus pyogenes would produce beta-hemolytic colonies, Corynebacterium diphtheriae would produce black colonies on tellurite agar, and Pseudomonas aeruginosa would produce greenish-blue colonies on cetrimide agar.
