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 45 year-old female with a past medical history significant for crohn's disease who presented to the emergency room with abdominal pain since midnight. the patient vomited every day for approximately three days. she vomited several times in the emergency room. the patient had a bowel movement the day prior to presentation, which was small and thin. the patient has been having chills, but no fevers. she has no diarrhea. the abdominal pain started relatively suddenly and it was sharp and stabbing. the patient could not move without pain. the patient consequently came to the emergency room for further evaluation. past medical history: 1. crohn's disease for approximately 25 years with large intestine fistulas. 2. colonoscopy in with the finding of a sigmoid stricture. past surgical history: none. medications: 1. imuran. 2. prednisone, which was started four days prior to presentation and the patient took 40 mg, denied before presentation. allergies: no known drug allergies. physical examination: temperature 99.2. heart rate 129. blood pressure 149/68. respiratory rate 20. 100% on room air. general examination the patient appeared to be pale in obvious distress. heent examination within normal limits. cardiac examination tachy with a regular rhythm. lung examination clear to auscultation bilaterally. abdomen no bowel sounds, abdomen distended and diffusely tender. there was shake, tenderness and tap tenderness. extremities were warm and well perfuse. no evidence of edema. laboratory studies: white blood cell 16.3, hematocrit 15.8, platelets 259. potassium 4.4, creatinine 0.8, lipase 14. imaging studies: a kub was obtained, which showed a question of pneumatosis coli and also free air surrounding the liver. ct of the abdomen showed bowel perforation with large amount of free air. hospital course: given signs of perforation and free air on imaging and significant physical examination the patient was admitted to surgery and taken to the operating room. prior to that she was aggressively resuscitated intravenous fluids and made npo. a nasogastric tube was inserted to low continuous wall suction and antibiotics were administered. on given the diagnosis of perforated transverse colon and perforated viscus the patient underwent a subtotal colectomy, hartmann's procedure and ileostomy and a take down of the splenic flexure. the patient tolerated the procedure well. there were no complications. she was successfully extubated and transferred to the post anesthesia care unit in stable condition. the patient was then transferred to the floor in stable condition. the nasogastric tube continued to be inserted and the patient again was resuscitated with intravenous fluids. after the post anesthesia care unit she was transferred to the intensive care unit for closer monitoring. the patient was extubated on postoperative day one. her pain was maintained with pca and she was on lopresor and stress steroid dose. the patient was aggressively diuresed with lasix. the diet was advanced from sips to clears, which she initially did not tolerate well and had some episodes of nausea and emesis. however, she eventually tolerated the diet. her ostomy was functioning well and eventually was putting out significant amount of material. the patient remained afebrile. her white blood cell count decreased. the patient was discharged to home on in stable condition. condition on discharge: good. discharge destination: home with vna services. discharge diagnoses: 1. perforated viscus and perforated transverse colon. 2. status post subtotal colectomy. 3. status post hartmann's procedure. 4. status post end ileostomy and take down of the splenic flexure. 5. crohn's disease. discharge medications: 1. imodium 2 mg po t.i.d. 2. tylenol 650 mg po q 4 to 6 hours as needed. 3. prednisone 10 mg po q.d. 4. protonix 40 mg po q.d. 5. percocet one to two tabs po q 4 to 6 hours as needed. 6. ostomy supplies as needed. discharge instructions: 1. the patient is to continue on a regular diet and boost supplements. 2. the patient is to see dr. the week of discharge for staple removal and wound check. , m.d. dictated by: medquist36 procedure: temporary ileostomy open and other resection of transverse colon diagnoses: acidosis anemia, unspecified perforation of intestine other b-complex deficiencies other nonspecific findings on examination of blood unspecified peritonitis regional enteritis of large intestine 

Answer: The patient is high likely exposed to
