Microbiology (diseases associated with infectious microbes)
A 33 year old man comes into the hospital for a check up. For the most part, the physician sees that everything is alright with the patient, but the patient complains about pain in the perianal region. The doctor rechecks the results of the patient and realizes that he lost about 30 lb. since the last time he came. When asked, the patient said that he has not been doing anything different in terms of lifestyle, but he has been enjoying a new BBQ place that opened 14 weeks ago. What other tests should be performed or what is your diagnosis?
