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 80 year-old male with coronary artery disease status post coronary artery bypass graft, abnormal stress test on with moderate to severe partially reversible inferior wall defect who presents with a low grade temperature a few days prior to admission subsequently developing a nonproductive cough. on the day of admission he became increasingly short of breath. he denies any chest pain. no nausea, vomiting or diaphoresis. the patient was having difficulty sleeping secondary to his cough and shortness of breath. in the emergency department the patient had an oxygen saturation in the 70s in room air and was tachypneic with a respiratory rate in the 40s to 50s. levofloxacin and flagyl were administered for possible pneumonia. the patient also received nebulizer treatment of supplemental o2 with an increase in his o2 sats to the 98 to 100% range and decrease in respiratory rate to the 30s. according to the patient's son the patient has had problems with dysphagia and difficulties related to eating. he occasional self induces vomiting to relieve himself. past medical history: 1. coronary artery disease status post coronary artery bypass graft in , moderate to severe inferior wall defect partially reversible, ejection fraction 60%, status post two myocardial infarctions in the past. 2. peripheral vascular disease status post fem fem bypass. 3. cardiac arrest status post coronary artery bypass graft on amiodarone. 4. hypothyroidism. no history of diabetes or hypertension. medications on admission: aspirin, plavix, levoxyl, prozac, lipitor, coumadin, lasix, spironolactone, protonix, metoprolol, amiodarone. allergies: fruit. physical examination on admission: temperature 99.2. heart rate 60. blood pressure 110/80. o2 sat 70% on room air, 100% on nonrebreather. in general alert, sitting up in bed tachypneic patient. pupils are equal, round and reactive to light. no jvp. rales half way up bilaterally in lungs. cardiac examination regular rate and rhythm. normal s1 and s2. abdomen soft, nontender, nondistended. extremities +1 pitting edema in both ankles. distal motor strength grossly intact in the upper and lower extremities. laboratory: arterial blood gases on nonrebreather was ph of 7.47, pco2 34, po2 67, sodium 136, potassium 6.3 hemolyzed. chloride 104, bicarb 23, bun 26, creatinine 1.1, glucose 122. white count 18.5, hemoglobin 10.5, hematocrit 31.4, platelets 487, pt 13.1, ptt 25.6, inr 1.2. urinalysis positive for nitrites, 3+ protein, many bacteria. ck 56, troponin less then 0.3. electrocardiogram showed sinus rhythm rate in the 60s, left atrial abnormality, left axis deviation. no ischemic st t wave changes. chest x-ray showed pulmonary congestion, bilateral alveolar infiltrates predominantly in the bases. hospital course: the patient was admitted to the micu given his guarded respiratory condition. for several days he continued to be tachypneic and was maintained either on nonrebreather or bipap machine. he ultimately needed to be intubated given a decompensating respiratory status. he was maintained on an antibiotic course of levofloxacin and ceftriaxone for pneumonia. his cardiovascular status also continued to decline. he ultimately needed pressors in order to maintain a mean arteriole pressure above a goal of 60 on . he was on a total of three pressors, levo at 10.6, neo at 140 and vasopressin at .02. during morning rounds the patient continued to decompensate on this day and all three pressors were at their maximum doses and the patient continued to become hypotensive despite this therapy. the patient's family was spoken to by dr. . the family agreed to discontinue the pressors as well as ventilatory support and the patient passed away soon afterwards. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours other endoscopy of small intestine insertion of endotracheal tube diagnoses: pneumonia, organism unspecified coronary atherosclerosis of native coronary artery congestive heart failure, unspecified other pulmonary insufficiency, not elsewhere classified unspecified septicemia iron deficiency anemia secondary to blood loss (chronic) unspecified acquired hypothyroidism aortocoronary bypass status hemorrhage of gastrointestinal tract, unspecified 

Answer: The patient is high likely exposed to
