G141

Gram – Groin abscess: gram positive bacilli + neutrophils  – Shipped May 2014

HISTORY

The challenge was sent to category A, B, C, and C1 laboratories. The sample was a simulated groin abscess fluid obtained from a 45 year old female diabetic patient admitted to emergency.

Laboratories were expected to report the presence of neutrophils and gram positive bacilli. Category A laboratories were also expected to correlate results with those obtained for the companion challenge, M141-5

MAIN EDUCATIONAL POINTS from G141

  1. With the presence of pus it is important to ensure that possible etiologies are considered for clinical interpretation and response.
  2. Not all coryneform/diphtheroid bacteria are superficial skin commensals. Identification may be important in the appropriate clinical situation.
