Overview
Laboratory Findings
Culture
- An epidermal swab of the affected region may provide samples of the pathogenic Corynebacterium minitissimum.[1]
- Corynebacterium minitissimum will present as non-hemolytic smooth colonies that are 1-1.5mm in size.[2]
- Due to the 2-3 week incubation requirements and the low sensitivity, culture analysis is not effective as a sole diagnostic measure.[3]
Gram staining
- [[Gram staining| analysis of Corynebacterium minitissimum will reveal the following:
