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 72-year-old male with a past medical history significant for atrial fibrillation and cerebrovascular accident causing aphasia who presented with a 5 cm abdominal aortic aneurysm that was infrarenal in nature. this has been monitored for approximately two years and was noted to be increasing in size, and he was admitted for elective repair. this was initially to be performed in ; however, on the day of admission, the patient developed vomiting after his admission, and his heart rate was noted to be approximately 140. he was then transferred to telemetry and ruled out by cardiac enzymes. cardiology ordered a cardiac catheterization which did not show any significant disease, and he was subsequently cleared for surgery. after that, upon entering the abdomen, a very enlarged inflamed gallbladder was found and removed. the patient was then discharged and readmitted on for a final elective abdominal aortic aneurysm repair. past medical history: significant for atrial fibrillation on chronic anticoagulation, ejection fraction noted to be approximately 35%, cerebrovascular accident in with residual aphasia and right upper extremity weakness, hypertension, increased cholesterol, hypothyroidism, chronic obstructive pulmonary disease, migraine headaches, and depression. past surgical history: significant for cholecystectomy in . medications on admission: coumadin 3 mg p.o. q.d., digoxin 0.125 mg p.o. q.d., toprol xl 100 mg p.o. q.d., synthroid 0.05 mg p.o. q.d., lipitor 10 mg p.o. q.d., zoloft 25 mg p.o. q.h.s. allergies: he admits to having an allergy to seafood which causes severe swelling in his face. physical examination: general: at the time of admission, the patient appeared to be a well-developed, well-nourished male appearing somewhat older than his stated age of 72. he was alert, awake, and oriented with expressive aphasia. neck: supple. no evidence of jugular venous distention. no carotid bruits. heart: irregular, rate, and rhythm. rate approximately 100. lungs: clear to auscultation bilaterally. no wheezes, rales, or rhonchi. abdomen: soft, nontender, nondistended. there was a well-healed surgical scar present in the midline. there was a nontender pulsatile mass. extremities: there were 2+ pulses, femoral through dorsalis pedis and posterior tibial bilaterally. neurological: the patient was able to speak clearly in short sentences but has difficulty with normal length conversations. his face was symmetric. tongue was midline. he had equal grips bilaterally. hospital course: the patient was admitted to on , where an abdominal aortic aneurysm repair was performed with the use of a dacron tube graft, details of which are dictated as separate operative note. the patient tolerated this procedure quite well and was subsequently transferred up to the vascular intensive care unit. upon arrival to the vicu, the patient was noted to be somewhat unresponsive and was being bagged by the nursing staff. he was able to arouse with voice and able to follow commands; however, he appeared to be in somewhat moderate respiratory distress. chest x-ray was obtained and revealed plate-like atelectasis and a possible collapsed right middle lobe, but no pneumothorax was noted. the patient improved somewhat with narcan and became more alert and oriented. he was monitored very closely throughout the next several hours with q.4 hour nebulizer treatments. he was maintained in the vascular intensive care unit with a pulmonary artery catheter. he continued to have rhonchi for the next several days. for his heart rate and atrial fibrillation, as he was tachycardiac on admission, he was maintained on a diltiazem drip, as well as intravenous lopressor q.4 hours, and he had good response to this. he did somewhat well over the next few days; however, he did have occasional problems with shortness of breath that would respond to lasix and nebulizer treatments. it was on postoperative day #5 when the patient began experiencing increasing shortness of breath without response to lasix or nebulizer treatments, and he was subsequently intubated on the floor. he was then transferred down to the surgical intensive care unit where he was monitored. chest x-ray was performed at that time which revealed a right-sided consolidation and possible increased effusion on the right side. sputum cultures were obtained, and the patient was started on levofloxacin. he did quite well and remained stable while he was intubated. on postoperative day #6, he was started on zosyn iv for greater gram-negative coverage. the cultures were obtained and revealed yeast, as well as gram-negative rods that eventually grew out enterobacter. he remained on intravenous zosyn throughout his stay in the intensive care unit and was also started on intravenous fluconazole for the yeast in his sputum. he remained in the intensive care unit for approximately four days, however was able to be extubated on postoperative day #8. he was then transferred up to the floor and monitored closely. it should be noted that during this time frame, he was also started on tpn, as he had been without nutrition oral replacement since the 13th. his coumadin and inr dosing were also monitored and maintained daily. he was eventually switched back over to oral levaquin, as the enterobacter was sensitive to this, and he was able to take oral diet. he was started on a clear liquid diet on postoperative day #12 and tolerated this quite well. at this time he is doing quite well. he is ambulating without difficulty and without the use of assistance. he is tolerating a regular diet without any nausea, vomiting, or abdominal pain. he has remained afebrile with stable vitals signs. he has been cleared by physical therapy for home discharge. his inr has been somewhat elevated for the last two days at 3.7 and 3.8. his coumadin on hold for the last two days and will be restarted tomorrow. he is to have the inr checked by visiting nurse tomorrow, and his dose is to be changed by his regular cardiologist dr. . he has been advised to follow-up with dr. in approximately two weeks or call should he have any difficulty. discharge medications: coumadin 2.5 mg p.o. q.d. to start , lopressor 100 mg p.o. b.i.d., digoxin 0.125 mg p.o. q.d., synthroid 50 mcg p.o. q.d., diltiazem cd 240 mg p.o. q.d., zantac 150 mg p.o. b.i.d., lipitor 10 mg p.o. q.d. discharge diagnosis: 1. abdominal aortic aneurysm status post repair with dacron tube graft. 2. pneumonia, currently resolved and off antibiotics. 3. cerebrovascular accident with residual aphasia that is stable. 4. rapid atrial fibrillation that is currently well controlled on p.o. lopressor and diltiazem. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified parenteral infusion of concentrated nutritional substances insertion of endotracheal tube pulmonary artery wedge monitoring resection of vessel with replacement, aorta, abdominal diagnoses: pneumonia, organism unspecified anemia, unspecified atrial fibrillation obstructive chronic bronchitis with (acute) exacerbation abdominal aneurysm without mention of rupture late effects of cerebrovascular disease, aphasia 

Answer: The patient is high likely exposed to
