M133-4

Joint Fluid (companion to G133): Kingella kingae  – Shipped November 2013

HISTORY

A simulated joint fluid collected from a 3 year old male with knee pain was sent to category A laboratories.

Participants were expected to isolate, identify, and report Kingella kingae. Participants were also expected to report antibiotic susceptibilities and correlate results with those obtained for G133.

MAIN EDUCATIONAL POINTS from M133-4

  1. Kingella kingae is the most common cause of septic arthritis in children under 4 years of age.
  2. Basic tests such as catalase oxidase, and indole, may be useful to indicate whether a result from a commercial identification system is likely to be correct or incorrect.
