Gram – Groin abscess: gram positive bacilli + neutrophils – Shipped May 2014
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
- With the presence of pus it is important to ensure that possible etiologies are considered for clinical interpretation and response.
- Not all coryneform/diphtheroid bacteria are superficial skin commensals. Identification may be important in the appropriate clinical situation.
