M164-5

Burn wound swab: Pseudomonas aeruginosa – Shipped February 20, 2017 

HISTORY

A simulated burn wound swab collected from a 40 year old patient, hospitalized, with abdominal burns was sent to category A laboratories.

Participants were expected to identify Pseudomonas aeruginosa and perform susceptibility testing.

MAIN EDUCATIONAL POINTS from M164-5

  1. P. aeruginosa isolated from significant infections such as in the thermally injured patient should be identified to the species level.
  2. Antimicrobial susceptibility testing should be performed and reported to standard antimicrobial agents used for treatment of P. aeruginosa, including ceftazidime, aminoglycosides (tobramycin and gentamicin, and amikacin if the first two are resistant), ciprofloxacin, and carbapenems (imipenem and meropenem). Other potential agents may be tested depending on availability and the results of primary testing.
