G171

Gram – Peritoneal fluid: 4+ (>10/oif) neutrophils, 3+ (11-50/oif) gram negative bacilli, (Klebsiella pneumoniae), and 3+ (11-50/oif) gram positive cocci (Streptococcus constellatus) – Shipped May 09, 2017

HISTORY

A simulated peritoneal fluid smear collected from a 50 year old patient with intra-abdominal sepsis was sent to category A, B, C, and C1 laboratories. Participants were expected to report neutrophils, gram negative bacilli, and gram positive cocci.

MAIN EDUCATIONAL POINTS from G171

  1. Most infections in the peritoneal cavity have a mixture of microorganism, often with anaerobic morphotypes involved.
  2. Participants should carefully review Gram smears from these types of specimens to ensure that the various morphological types are no missed.
