Groin abscess: Actinomyces neuii – Shipped May 2014
The challenge was sent to category A laboratories. The sample was a simulated groin abscess fluid obtained from a 45 year old female diabet-ic patient admitted to emergency.
Laboratories were expected to isolate, identify, and report Actinomyces neuii.
MAIN EDUCATIONAL POINTS from M141-5
- Actinomcyes neuii has often been missed as a cause of soft tissue infections. It may be passed over as a coryneform of the skin and not associated with the infectious process.
- Laboratories should be aware that such species exist and can be associated with soft tissue abscesses, often in the groin, breast, and other moist intertriginous areas. It is likely they have been under reported since described early in the 1990s.
