Overview
Laboratory Findings
Laboratory tests and findings for Erysipelas include those used to confirm streptococcal infection for pathogenic strains.
Culture
- Swab of affected region may provide samples of pathogenic streptococci, including Streptococcus pyogenes[1]
- Streptococci will usually be grown on agar media to produce β-hemolysis for subsequent identification and specification.
- Streptococcus pyogenes will display as smooth, white-grey domes surrounded by β-hemolysis.
- They will be arranged in chain formation as Gram-positive cocci when examined microscopically.
