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: this 64 year-old white male was transferred to from hospital. he was admitted there on after presenting to the emergency department with complaints of seven days of weakness, fatigue and shortness of breath. he had undergoing a low anterior colon resection on for rectosigmoid carcinoma and his postop course from that was apparently uneventful. on he received 2 units of packed cells when he was found to be anemic with a hematocrit of 27. in the emergency department he was significantly dehydrated with acute renal failure with a bun of 56 and a creatinine of 3.1. intravenous fluids resuscitation precipitated pulmonary edema requiring emergency intubation. he was given lasix with no response. his white blood cell count in the emergency room was . he was admitted to the coronary care unit for sepsis and respiratory failure and required large amounts of fluid. he had a significant murmur and there was evidence of anterolateral st depression on the electrocardiogram. his troponin was 10.9. he was started on unasyn and levaquin and was then diuresed. a swan was placed and revealed a cardiac index of 1.9 and he was placed on dopamine and his cardiac index increased to 2.9. an echocardiogram revealed mitral valve vegetation, mitral valve prolapse with a large mobile anterior leaflet vegetation, which flopped into the antrum and moderate mitral regurgitation. an abdominal ct was performed, which revealed no evidence of significant intraabdominal fluid collection or other anatomical abnormalities. he was started on tube feeds. gentamycin was added. he had blood cultures, which were positive for strep viridans and was sensitive to penicillin and ceftriaxone. his creatinine did continue to improve with a creatinine of 2.1 on hospital day number five. he remained in pulmonary edema, remained intubated and he was transferred for further treatment. past medical history: significant for status post lower anterior resection for large invasive rectosigmoid carcinoma in at hospital, status post inguinal hernia repair 20 years prior to admission. history of diverticulitis. medications at home: nexium q.d. allergies: no known drug allergies. medications on transfer: 1. unasyn 3 grams intravenous q 8 hours. 2. levaquin 500 mg intravenous q day. 3. epogen 10,000 units subq q week. 4. ________ albumin with lasix q 12 hours. 5. heparin 5000 units subq b.i.d. 6. morphine prn. 7. ativan prn. 8. dopamine drip at 2 mg per kilograms per minute. social history: he does not smoke cigarettes and drank in the past, but has not had a drink in one month. family history: unremarkable. review of systems: as above. physical examination: he is a thin white male intubated. vital signs were stable. his temperature was 98.8. his heent examination normocephalic, atraumatic. extraocular movements intact. oropharynx benign. neck was supple. full range of motion. no lymphadenopathy or thyromegaly. carotids 2+ and equal bilaterally without bruits. lungs have rhonchi on the left. his cardiovascular examination is regular rate and rhythm with a holosystolic murmur. abdomen was slightly distended and nontender with a well healed surgical scar. extremities were without clubbing, cyanosis or edema. neurological examination was nonfocal. hospital course: he was transferred to the csru. he was seen by dental who had a limited examination due to the et tube, but saw no evidence of dental infection. he was seen by cardiology. id also saw him and they recommended discontinued levofloxacin and continuing the unasyn. he remained in the unit and transesophageal echocardiogram revealed severe mitral regurgitation with partial flail leaflets and a 1.8 by 1.1 cm vegetation. he had a balloon placed and that remained in and on he underwent a coronary artery bypass graft times four with left internal mammary coronary artery to the left anterior descending coronary artery, reverse saphenous vein graft to the right coronary artery, obtuse marginal and diagonal and a mitral valve replacement with a #29 mosaic porcine valve. the cross clamp time was 146 minutes, total bypass time 164 minutes. he was transferred to the csru on propofol in stable condition. he remained intubated and was on neo and propofol on postop day one. he was switched at that point to ampicillin 2 grams intravenous q 6 hours and that was recommended to have a four week course. his balloon was removed on postoperative day number one and he remained on a pressure support wean. he was extubated on postoperative day three. he did have a hoarse voice and difficulty swallowing. he was fed with tube feeds. he had a bedside swallowing evaluation, which they felt he was aspirating, so he was kept npo and on tube feeds. he continued to progress very well, although he was markedly fatigue and weak. he did go into atrial fibrillation on postop day five. he converted with amiodarone and lopressor. he did continue to have frequent bursts of atrial fibrillation that would be very short and he eventually was anticoagulated. he was seen by ep who recommended the amiodarone and they wanted upon discharge for him to have of hearts monitor while he was having his amiodarone load for two weeks following discharge. eventually he was transferred to the floor on postoperative day number six and he continued to slowly improve. he did have another swallowing evaluation and they felt he could have nectar thick liquids and regular food, which he was slow to eat at first due to loss of appetite, but has been improving with that. he also requires boost pudding and thick shakes. he was on heparin and coumadin, slowly anticoagulated. his pacing wires were discontinued. he continued to improve and on postop day number twelve was transferred to rehab in stable condition. laboratories on discharge: white blood cell count 11,600, hematocrit 38.9, platelets 285, sodium 140, potassium 4.1, chloride 107, co2 23, bun 27, creatinine 1.1, blood sugar 91, pt 40.4, inr 1.4. medications on discharge: 1. ampicillin 2 grams intravenous q 6 hours for twelve more days. 2. colace 100 mg po b.i.d. 3. percocet one to two po q 4 to 6 hours prn for pain. 4. he will receive 5 mg of coumadin tonight and then should be dosed to keep his inr between 2 and 2.5. 5. aspirin 81 mg po q.d. 6. nystatin swish and swallow 5 cc oral q.i.d. 7. amiodarone 600 mg po q.d. for four more days and then decrease to 400 mg po for three weeks and then decrease to 200 mg po q.d. be transferred to with of hearts monitor for two weeks. the strip should be sent to dr. at the . he will also have an appointment with him in one month following discharge and needs an appointment with dr. in one to two weeks after discharge and with dr. in four weeks. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for 96 consecutive hours or more (aorto)coronary bypass of three coronary arteries single internal
