Chapter 45, Problem 1CA
An 8-year-old boy went to the pediatrician complaining of pain in his right hip. He had no previous injury to the hip or leg. His temperature was 38°C. A bone scan revealed damage to the head of the femur. Bacterial cultures of blood and fluid from the hip joint were positive for a gram-positive, catalase-positive, coagulase-positive coccus that ferments mannitol. Use Appendix H to identify the species of this bacterium.

She appeared fatigued, had tender joints, and complained of a headache, a stiff neck and a backache. The physician noticed a circular "rash" about 5 inches in diameter, with a bright red leading edge and a dim center in the form of a "bull's eye." The physician noted an irregular heartbeat. The patient complained of lack of ability to concentrate. The patient gave the following history: She is a graduate student in the wildlife program at the university in town. She was in the field for three weeks in Wisconsin during the months of May and June. She tracks small mammals in the field and studies their behavior. It had been a warm, wet spring and she complained of a large number of biting flies, mosquitoes and ticks in the area. She felt well until about two weeks after returning to her home.

At the time of the hospital admission, a urine culture was obtained and revealed >100,000 CFU/ml of an Escherichia coli strain that was susceptible to all antimicrobial agents against which it was tested. Postoperatively, she began a 7-day course of oral cephalexin. She was discharged after an uneventful postoperative course of 3 days. Ten days postoperatively, she presented with a 3-day history of diarrhea. The patient noted multiple watery, loose stools without blood, crampy abdominal pain, and vomiting. She presented with a temperature of 38.2 degrees C, pulse rate of 90/min, respiration rate of 20/min, and blood pressure of 116/53mm Hg. Her white blood cell count was normal, but a large number (53%) of immature polymorphonuclear cells were seen.
