A cat lover of many years was bitten on her right thumb. Over the next few days the thumb became swollen and red and did not improve. She went to the emergency department where the wound was debrided and drained. She was started on ampicillin therapy. The culture grew Staphylococcus aureus at 24 hours but a small gram-negative rod was seen on the blood agar plate at 48 hours. The rod was unable to grow on MacConkey agar but was oxidase- and indole-positive and fermented a variety of sugars. It was identified by the laboratory's gram-negative identification system.
