M132-4

Blood culture: Pediococcus acidilactici – Shipped August 2013

HISTORY

The challenge was sent to category A laborato-ries. The sample was a simulated blood culture obtained from a 42 year old, male, bone marrow transplant, in-patient with a line infection.

Participants were expected to isolate and identify Pediococcus acidilactici and to perform anti-microbial susceptibility.

MAIN EDUCATIONAL POINTS from M132-4

  1. Pediococcus species isolated from clinically significant sites, such as blood cultures, deep tissue and sterile fluids should be reported with susceptibility results.
  2. The susceptibility report should include the comment that Pediococcus species is intrinsically resistant to vancomycin and communication with infectious diseases clinicians is recommended.
