Review Question - QID 218700

An 18-month-old child presents with a 3-day history of worsening left hip pain. According to her parents, she began walking at age 12 months and is normally ambulatory. They deny any recent trauma and have not traveled recently. They only endorsed a brief upper respiratory infection in the child a few weeks ago. On physical examination, the patient cries with any movement of her left hip. Laboratory studies include a serum white blood cell count of 11,300/mm3, ESR of 26 mm/hr, and CRP of 22 mg/L. Ultrasound examination of the left hip demonstrates a joint effusion. Ultimately the decision was made to aspirate the joint for synovial fluid analysis. Which of the following images depicts the most likely infectious organism?
