A 38-year-old woman presented to her clinician with a red, swollen right finger. The patient reported a dog bite two days prior. The clinician submitted a swab of the finger for Gram stain, aerobic, and anaerobic bacterial cultures. The Gram stain is shown in Image 1.  After 24 hours of incubation, bacterial grown was noted on sheep blood agar (Image 2) but not the eosin methylene blue agar. A drop oxidase was positive as shown in Image 2.
