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.

I love the cases, short and sweet.

I Love seeing my hypothesis being proved right (most of the time) :). It keeps me engaged and really gets me to think my answer to the question thoroughly through.

I enjoy these very much.

Ilove this

Thanks for challenging my dormant micro skills!

I am a microbiologist and we have seen this fairly often with animal bites

Thank you for this presentation.

Ok, the correct answer is Pasteurella multocida.
