M171-4

Blood: Bacteroides fragilis  – Shipped May 09, 2017 

HISTORY

A simulated blood culture sample collected from a 57 year old male with bowel obstruction was sent to category A laboratories. Participants were expected to isolate and identify Bacteroides fragilis group. No susceptibility testing was required.

MAIN EDUCATIONAL POINTS from M171-4

  1. The importance of communication between the laboratory and the clinician alerting of a presumptive Bacteroides fragilis group because they are resistant to more antimicrobial agents than most other anaerobic organisms.
  2. Members of Bacteroides fragilis group are the most frequently isolated anaerobic pathogens from bloodstream infections.
