Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: history of present illness: the patient is a 23-year-old male with a past medical history of crohn's, status post small bowel resection x 3, last in , who was recently admitted to , an outside hospital, on , where he presented with 12 hours of severe abdominal pain. he was noted to have severe abdominal pain the night prior to admission to the outside hospital, followed by nausea and vomiting. he is now transferred to the after he developed septic parameters at the outside hospital. past medical history: significant for crohn's disease. past surgical history: small bowel resections x 3. medications: mercaptopurine 100 mg by mouth twice a day, folate and vitamin b12. allergies: no known drug allergies. physical examination: on examination, the patient is a white male who appeared somnolent and was lying still. vitals were a temperature of 99.6, heart rate 130, blood pressure 146/74, oxygen saturation 96% on room air. on examination, there was a nasogastric tube in place. pulmonary examination revealed tachypnea though the lungs were clear to auscultation bilaterally. cardiac examination revealed tachycardia with a regular rhythm. the abdomen was distended, tense. there was guarding and rebound tenderness present. there were no bowel sounds. the extremities were warm and well perfused. laboratory data: from , white count 17.2, with a differential of 77 neutrophils, 3 bands. hemoglobin was 13.2, platelets were 240. sodium was 139, potassium 4.4, chloride 98, bicarbonate 30, bun 12, creatinine 0.8, glucose 119. lactate was 43.9. total bilirubin was 2.8. ast was 36, alt 113, alkaline phosphatase 82, direct bilirubin 0.5, amylase 68. ct scan: at the outside hospital, revealed on scanning of the abdomen and pelvis, there was some free fluid present in the abdomen, and the ct was read as consistent with small bowel obstruction. hospital course: the patient was admitted to the general surgery service. aggressive fluid resuscitation was started, and the patient was prepared and taken to the operating room, at which point he was found to have a mid-gut volvulus with severe ischemic compromise, and he underwent an exploratory laparotomy and derotation of a mid-gut volvulus. please see the operative note for details. following the procedure, the patient was transferred to the post-anesthesia care unit in stable but guarded condition, and was subsequently transferred to the surgical intensive care unit. the patient was stable following the initial procedure, during which a second look operation was planned. the patient was maintained intubated and sedated on postoperative day one, and lactate was found to be 2.2. white count was 6.2, with 14 bands. when the patient was taken back to the operating room for the second look laparotomy, he underwent segmental small bowel resection with re-anastomosis. please see the operative note for details. the patient was transferred back to the surgical intensive care unit following the procedure. the patient remained intubated following the procedure, and was subsequently intubated on postoperative day two from the original procedure. at the time of the second operation, in addition to intravenous fluids, the patient also received two units of packed red blood cells, two units of fresh frozen plasma, and a five-pack of platelets. on postoperative day three from the original procedure, the patient was doing well, and was transferred to the floor. the patient was also started on total parenteral nutrition. the patient was still noted to be febrile on postoperative day four. please note that postoperative antibiotics consisted of zosyn. by postoperative day six, the patient was on no antibiotics, however, he was still found to be febrile, with evidence of a right pleural effusion on chest x-ray, with no pneumonia. a central line tip was sent for culture. on postoperative day seven, a kub was obtained to evaluate the position of the patient's nasogastric tube. it was withdrawn slightly, with good effect. on postoperative day eight, the patient was noted to have had a small bowel movement overnight, with no nausea or vomiting. total parenteral nutrition was continued. a picc line was to be placed for long-term total parenteral nutrition, however, the patient was still febrile. oxacillin was started. a ct scan was obtained on , which showed no abscess, no free air, and no extraluminal contrast was detected, and prominent small bowel loops were seen. on postoperative day nine from the original procedure, the nasogastric tube was removed. the patient continued to improve, was passing stool, and total parenteral nutrition was continued. a picc line was placed in the right basilic vein for total parenteral nutrition. the patient's diet was advanced to sips of clear liquids. on postoperative day 11, the patient was found to be febrile, and was advanced to full clears. on postoperative day 12, the patient was afebrile, and tolerated a soft diet. arrangements were made for the patient to continue total parenteral nutrition at his home in , and the patient was advised to follow up with dr. at the regarding adjustment of total parenteral nutrition as well as postoperative follow up. the patient was discharged and was contact following discharge and the total parenteral nutrition home services had been set up successfully. condition at discharge: stable. discharge status: discharged to home with home total parenteral nutrition services. discharge diagnosis: 1. crohn's disease 2. small bowel volvulus with extensive resection 3. status post exploratory laparotomy with derotation of mid-gut volvulus 4. status post second look laparotomy with small bowel resection and anastomosis discharge medications: 1. dilaudid 2 to 4 mg by mouth every four to six hours as needed for pain 2. total parenteral nutrition follow-up plans: the patient was to follow up with dr. at the for total parenteral nutrition adjustment as well as to follow up at the for management of his crohn's disease. , m.d. dictated by: medquist36 procedure: parenteral infusion of concentrated nutritional substances other partial resection of small intestine intra-abdominal manipulation of small intestine diagnoses: pneumonia, organism unspecified acidosis unspecified pleural effusion regional enteritis of unspecified site other specified surgical operations and procedures causing abnormal patient reaction, or later complication, without mention of misadventure at time of operation volvulus 

Answer: The patient is high likely exposed to
