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 63-year old female with a past medical history significant for schizophrenia, mental retardation, and status post subtotal colectomy for ischemic colitis in who now presents to the emergency department with complaints of abdominal pain and vomiting times three days. she denies any hematemesis, fevers, chills, or sweats but has had diarrhea for two days. she has not had any melena, or hematochezia, or dysuria. she denies any cough, shortness of breath, or chest pain. her abdominal pain is severe, sharp, nonradiating, and constant. past medical history: schizophrenia. mental retardation. history of ischemic colitis. hiatal hernia. gastritis. recurrent urinary tract infections. depression. anxiety. past surgical history: status post subtotal colectomy. status post ventral hernia repair. status post excision of sebaceous cyst. medications on admission: 1. anusol as needed. 2. ativan 0.5 mg once per day. 3. calcium carbonate 500 mg once per day. 4. celexa 40 mg once per day. 5. desitin as needed. 6. detrol 1 mg twice per day. 7. eucerin as needed. 8. lomotil 2.5/0.25 twice per day and as needed. 9. maalox as needed. 10. metamucil once per day. 11. neurontin 300 mg twice per day. 12. zantac 150 mg twice per day. 13. trazodone 100 mg at hour of sleep. 14. zyprexa 40 mg twice per day. allergies: penicillin and sulfa, pyridine. physical examination on presentation: vital signs revealed a temperature of 96, her heart rate was 127, her blood pressure was 126/76, her respiratory rate was 18, and 94 percent on room air. in general, awake and alert, in mild distress. respiratory examination revealed clear to auscultation bilaterally. cardiovascular examination revealed a regular rate and rhythm. gastrointestinal revealed protuberant, soft, and nondistended. epigastric tenderness to palpation with no guarding or rebound tenderness. extremities were warm with no edema. pertinent laboratory values on presentation: white blood cell count was 17.1, her hematocrit was 46.3, and her platelets were 224. sodium was 131, potassium was 4.7, chloride was 95, bicarbonate was 24, blood urea nitrogen was 43, creatinine was 1.2, and blood glucose was 230. her alanine-aminotransferase was 27, her aspartate aminotransferase was 52, her alkaline phosphatase was 127, her total bilirubin was 2.1, her amylase was 529, and her lipase was 517. lactate was 3. pertinent radiology-imaging: a computed tomography of the abdomen and pelvis revealed cholelithiasis, ascites, common bile duct dilatation to 1 cm, pancreas with marked inflammation and areas of nonenhancement. summary of hospital course: the patient was admitted on for management of her necrotizing gallstone pancreatitis that was evident on computed tomography scan. she was intubated for respiratory distress, and a gastroenterology consultation was obtained. they recommended that the patient be placed on imipenem empirically for antibiotic coverage. they also recommended that endoscopic retrograde cholangiopancreatography be performed during the next day following admission if the patient's clinical course declined. she was given aggressive hydration intravenously. she was admitted to the intensive care unit for further management. over the next two days, the patient began to improve with a decreasing amylase to 95. her white count also decreased to 12.1 from 17. it was decided that she would not undergo endoscopic retrograde cholangiopancreatography at this time. throughout the rest of her intensive care unit course, the patient remained nothing by mouth. she was started on total parenteral nutrition for nutrition. she was finally weaned off the ventilator on . she was finally transferred to the floor on for further care. she remained stable while on the floor. she was continued on her imipenem for a planned antibiotic course of 21 days. she was also started on an oral diet on which the patient tolerated. she is to be weaned off her total parenteral nutrition appropriately and is being planned for discharge to rehabilitation on . it seems that her episode of pancreatitis has resolved. discharge status: to rehabilitation. condition on discharge: stable. discharge diagnosis: necrotizing gallstone pancreatitis. discharge instructions-followup: the patient was instructed to follow up with dr. within three weeks. the patient was to be weaned off her total parenteral nutrition as she increases her by mouth intake. medications on discharge: 1. anusol as needed. 2. ativan 0.5 mg once per day. 3. calcium carbonate 500 mg once per day. 4. celexa 40 mg once per day. 5. detrol 1 mg twice per day. 6. lomotil 2.5/0.25 twice per day and as needed. 7. metamucil once per day. 8. neurontin 300 mg twice per day. 9. zantac 150 mg twice per day. 10. trazodone 100 mg at hour of sleep. 11. zyprexa 40 mg twice per day. 12. imipenem 500 mg q.6h. (times five additional days - until ). , procedure: venous catheterization, not elsewhere classified continuous invasive mechanical ventilation for 96 consecutive hours or more parenteral infusion of concentrated nutritional substances insertion of endotracheal tube transfusion of packed cells diagnoses: methicillin susceptible staphylococcus aureus septicemia unspecified schizophrenia, unspecified dysthymic disorder calculus of gallbladder without mention of cholecystitis, without mention of obstruction infection and inflammatory reaction due to other vascular device, implant, and graft acute pancreatitis unspecified intellectual disabilities 

Answer: The patient is high likely exposed to
