A 34-year-old Caucasian male presents to your office with abdominal cramps, watery stools and mild fever. His symptoms started two days ago, and he has tried several over-the-counter anti-diarrheal agents without any success. He denies any gross blood or black discoloration of the stool, nausea and vomiting, although he admits that his appetite has decreased a little. His past medical history is significant for a recent episode of acute sinusitis treated with amoxicillin. He does not smoke or consume alcohol. He denies any recent travel or contact with a patient with similar symptoms. He is sexually active with his wife and uses condoms for contraception. He works as a programmer at a private firm and does not consider his job stressful. Physical examination reveals mild tenderness in the left lower quadrant of his abdomen. His stool is positive for occult blood, but is negative for C. difficile toxin by rapid immunoassay.
Which of the following is the best next step in the management of this patient?
