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 64 year old male with a history of hypertension, hbv and diabetes mellitus who presented with abdominal pain and abnormal liver function tests. the patient was referred to for an ercp. during the ercp small ductal stones were removed and a large diverticula was noted near the papilla. the patient underwent sphincterotomy complicated by mild bleeding from the diverticulum, which was later cauterized by epinephrine injection on egd. the patient was transferred to the floor and developed hypotension and fevers to 102.0 f. physical examination: on admission, the patient's blood pressure is 105/75; heart rate 110; respiratory rate 12; saturation at 100% on two liters. heent: extraocular muscles are intact. mildly icteric sclerae. neck: jugular venous distention flat; supple. lungs clear to auscultation bilaterally. heart is regular rate and rhythm, no murmurs, rubs or gallop. abdomen was soft, nontender, with decreased bowel sounds. extremities cool, no edema. palpable pulses. admission laboratory: the patient had a white blood cell count of 11.6, hematocrit 28, platelets 172. sodium 140, chloride 112, carbon dioxide 17, bun 20, creatinine 1.1, glucose 187. coagulation studies were 14.1, 33 and 1.4. alt was 372, ast 483, alkaline phosphatase 76, total bilirubin 2.8 with a direct of 1.3. albumin 4.2. arterial blood gas showed 7.4/36 and 127. lactate 2.8. hospital course: the patient was admitted to the medical intensive care unit with hypotension and fever of ercp complication. 1. cardiac: the patient admitted to the unit with hypotension. he became hemodynamically stable after packed red blood cell transfusion and fluids. 2. respiratory: stable without any event. 3. gastrointestinal: choledocholithiasis status post ercp and sphincterotomy with resultant bleeding from papilla. the patient then received egd with epinephrine injection to stop bleeding which was successful. pancreatitis from post-ercp, lipase and amylase were elevated but became normal. of note, the patient also had an increased bilirubin. 4. infectious disease: the patient was febrile after procedure. started on ampicillin and flagyl in the unit and changed to levaquin and flagyl. there was no evidence of ascending cholangitis on the ercp, but due to increased white blood cell count and fever, these antibiotics were started for gi pathogens. blood cultures remained negative. 5. endocrine: the patient was placed on insulin sliding scale and blood sugars were followed. he will f/u with his pcp, . . , m.d. dictated by: medquist36 procedure: other endoscopy of small intestine endoscopic removal of stone(s) from biliary tract endoscopic sphincterotomy and papillotomy diagnoses: hemorrhage complicating a procedure cholangitis acute pancreatitis calculus of gallbladder and bile duct without cholecystitis, without mention of obstruction 

Answer: The patient is high likely exposed to
