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 stain analysis of Corynebacterium minitissimum, a gram-positive will reveal the following:[4]
- Violet or blue coloration due to gram-positive rods reacting with the gram-stain
- Slightly curved bacterial rods[5]
