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 an 83-year-old female who had a colonoscopy and polypectomy three days prior to presentation. the patient went home and had two days of bright red blood per rectum. she also developed right lower quadrant pain which seemed to be getting worse. she spiked a fever up to 103 degrees fahrenheit with worsening of pain and distention, at which point she presented to the emergency department. past medical history: 1. status post right hip hemiarthroplasty in , complicated by hematoma and protracted drainage. 2. chronic obstructive pulmonary disease. 3. coronary artery disease. 4. congestive heart failure (with an ejection fraction of 25%). 5. atrial fibrillation. 6. polymyalgia rheumatica. 7. asthma. 8. hypercholesterolemia. 9. hypertension. 10. chronic renal insufficiency. 11. osteopenia. 12. hypothyroidism. 13. depression. 14. history of lower gastrointestinal bleed in , at which time colonoscopy revealed diffuse polyposis with pan-colonic bleeding from multiple polyps. medications on admission: 1. albuterol. 2. atrovent. 3. verapamil. 4. prednisone 3 mg by mouth once per day. 5. lasix 20 mg by mouth once per day. 6. lipitor. 7. protonix. 8. detrol. 9. levoxyl. 10. buspirone. 11. multivitamin. 12. digoxin. allergies: physical examination on presentation: physical examination revealed a pleasant and cooperative female in mild distress. temperature was 102 degrees fahrenheit, her heart rate was 80, her blood pressure was 123/42. cardiovascular examination revealed irregularly irregular. the lungs were clear to auscultation bilaterally. the abdomen was distended and tympanitic. very tender to palpation; worse in the right lower quadrant with rebound. rectal examination revealed decreased tone and occult-blood positive. during examination by dr , the patient had a large frankly melenic stool. pertinent laboratory values on presentation: laboratories revealed her white blood cell count 16.8, her hematocrit was 26.5 (decreased from 36.9 four months prior), and her platelets were 262. her inr was 1.1. sodium was 140, potassium was 4.1, chloride was 109, bicarbonate was 21, blood urea nitrogen was 29, and her creatinine was 1.6. pertinent radiology/imaging: a chest x-ray was within normal limits. electrocardiogram revealed a left bundle-branch block. no changes from prior electrocardiogram. a computed tomography scan was interpreted to show acute appendicitis. concise summary of hospital course: the patient was taken to the operating room on and underwent a subtotal colectomy, ileoproctostomy, and splenectomy. please see the operative note for details. due to the patient's guarded status, she was kept in the postanesthesia care unit and then transferred to the intensive care unit. on postoperative day one, she was successfully extubated. however, over the next two days she started spiking fevers up to 102 degrees fahrenheit and went into respiratory distress with difficulty breathing and decreased pco2 and had to be reintubated. her sputum culture grew gram-negative rods. the patient was started on ceftriaxone and ciprofloxacin. one day later she grew gram-negative rods in bottles, at which point vancomycin and flagyl were added. she was also started on tube feeds for nutritional support. the infectious disease service was consulted for continuous fever spikes and antibiotics and agreed with management. on postoperative day seven, the patient's ceftriaxone and flagyl were discontinued. the patient remained intubated and in respiratory distress. the patient went into atrial fibrillation. the patient was again extubated on postoperative day eleven; however, again she went into respiratory distress and was emergently reintubated. the patient's atrial fibrillation was becoming more difficult to rate control with increasing of lopressor. the patient had a couple of episodes of bradycardia. the electrophysiology service was consulted who recommended switching the patient to amiodarone. they also started anticoagulation with heparin. digoxin was discontinued. the patient had an echocardiogram which showed an ejection fraction of 45%. the patient also started growing methicillin-resistant staphylococcus aureus out of her sputum cultures. the patient's antibiotics were adjusted to zosyn and flagyl. on postoperative day seventeen, the patient's liver function tests were noted to increase. on postoperative day eighteen, the patient underwent a computed tomography scan which showed a distended gallbladder and dilated common bile duct. unable to wean off of ventilator. the gastrointestinal service was consulted, and the patient underwent an endoscopic retrograde cholangiopancreatography on which showed a stone in the middle of the common bile duct. a stent was placed. a sphincterotomy was not performed due to the patient's coagulation status. due to the patient's prolonged/extended distended gallbladder, a percutaneous cholecystostomy tube was placed. the patient had a few more episodes of poorly controlled atrial fibrillation and was started on amiodarone. a chest x-ray showed increased pleural effusion, and an ultrasound-guided thoracentesis was performed which drained 100 cc of yellow fluid. the patient continued to have respiratory distress with large amounts of thick secretions with suctioning of the lungs almost around the clock. otherwise, she remained stable and afebrile. a long discussion was held with the family who wished to extubate the patient and change her status to do not resuscitate/do not intubate which was done on . the patient remained stable, however, guarded. she continued to have ectopy. her status was changed to comfort measures only on . the patient continued to have ectopy which was increasing in frequency and severity. the patient's respiratory status was also slowly decreasing until she finally desaturated and ceased to have a blood pressure and heart rate and was pronounced dead. discharge diagnoses: 1. lower gastrointestinal bleed. 2. status post colectomy. 3. status post splenectomy. 4. appendicitis. 5. chronic obstructive pulmonary disease. 6. respiratory distress and prolonged intubation. 7. failure to thrive. 8. prolonged tube feeds and total parenteral nutrition. 9. status post right hemiarthroplasty. 10. atrial fibrillation. 11. polymyalgia rheumatica. 12. asthma. 13. hypertension. 14. hypercholesterolemia. 15. chronic renal insufficiency. 16. hypothyroidism. 17. osteopenia. 18. depression. , m.d. dictated by: medquist36 d: 07:46 t: 08:24 job#: procedure: venous catheterization, not elsewhere classified 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 other electric countershock of heart thoracentesis other and unspecified partial excision of large intestine endoscopic insertion of stent (tube) into bile duct other small-to-large intestinal anastomosis total splenectomy diagnoses: unspecified pleural effusion urinary tract infection, site not specified congestive heart failure, unspecified acute posthemorrhagic anemia atrial fibrillation methicillin susceptible staphylococcus aureus septicemia acute respiratory failure calculus of bile duct without mention of cholecystitis, without mention of obstruction acute appendicitis with peritoneal abscess 

Answer: The patient is high likely exposed to
