M203-5

Blood: Granulicatella adiacens  – Shipped November 02, 2020

HISTORY

A simulated blood culture collected from a 45 year old female with fatigue was sent to category A laboratories. Participants were expected to isolate, identify, and perform antimicrobial susceptibility testing of Granulicatella adiacens.

MAIN EDUCATIONAL POINTS from M203-5

  1. Granulicatella adiacens and other nutritionally variant streptococci (e.g., Abiotrophia defectiva, other Granulicatella species) are infrequent but important isolates from blood cultures.
  2. Media or techniques (e.g., chocolate agar or a streak of Staphylococcus aureus) that allow for these organisms to be isolated from blood cultures should be routinely used.
