GS162-1

Gram – CSF:  neutrophils, gram positive cocci (group B Streptococcus) – Shipped August 15, 2016

HISTORY

A simulated CSF smear collected from a febrile newborn was sent to category A, B, C, and C1 laboratories for Gram staining.

Participants were expected to report the presence of neutrophils and gram positive cocci.

 

MAIN EDUCATIONAL POINTS from GS162-1

  1. Cerebrospinal fluids are critical specimens, and rapid and accurate reporting of cells and bacteria from Gram stains, when present, is key to providing timely and appropriate therapeutic care.
  2. Gram positive cocci resembling streptococci (that is, in pairs or chains) are always an important finding in Gram stains of CSF, and may represent a number of pathogens, including Streptococcus agalactiae, a major etiologic agent of neonatal meningitis.
