A 18-year-old male present to the outpatient clinic for evaluation of diarrhea and abdominal discomfort. The patient noted mild abdominal discomfort and 3 watery bowel movements per day. Abdominal exam was notable for mild lower abdominal tenderness. Fecal exam demonstrated a greenish, watery stool, negative for occult blood.
Stool for fecal leukocytes was positive. The causative agent recovered from the feces was a slightly curved, gram-negative rod.
What is the probable etiological agent?
How is the organism cultivated?
How is the organism identified?
I was originally thinking of Campylobacter jejunii, but ruled it out due to the negative occult blood test.
