The laboratory reports that both blood cultures that are drawn from a 15 year old girl are growing Bacteroides fragilis. She was admitted to the hospital because of acute abdominal pain. You should be concerned that:
A. She has acute gastroenteritis and the organism is entering the blood from the inflamed bowel endothelial surface
B. She has a bowel perforation and intraabdominal tissue destruction with impaired vascular flow
C. She has gram negative sepsis and the Bacteroides is a contaminant
D. She has pelvic inflammatory disease with gonorrhea, a sexually transmitted disease, and the Bacteroides is a contaminant

Bacteroides fragilis is a common organism in the stool. We see it in cultures of abdominal abscesses when the stool contents spills into the gut, i.e. a burst appendix. I go with B.
I can't imagine a scenario where B. fragilis would ever be considered a contaminant in a blood culture.

My mistake, I read the question wrong, B does make more sense with B fragilis.
