M173-5

CSF: Streptococcus pneumoniae  – Shipped November 06, 2017

HISTORY

A simulated cerebrospinal fluid (CSF) sample collected from a 4 year old male patient was sent to category A laboratories.

Participants were expected to isolate and identify Streptococcus pneumoniae, report susceptibility results, and report the organism to Public Health authorities.

MAIN EDUCATIONAL POINTS from M173-5

  1. The overall incidence of bacterial meningitis in infants and children has decreased since the routine use of conjugated vaccines targeting Streptococcus pneumoniae, but remains an important bacterial cause of meningitis, particularly in adults.
  2. For Streptococcus pneumoniae isolated from CSF, penicillin and cefotaxime/ceftriaxone should be tested by a reliable minimal inhibitory concentration method.
