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 84 year old male with severe aortic stenosis with an aortic valve area of 0.6 square centimeters, coronary artery disease, status post stent placement in , complicated by in-stent restenosis in , who was admitted to on , with right lower quadrant pain. he was diagnosed with a right lower quadrant abscess, possibly related to diverticulosis and underwent percutaneous drainage on . cultures grew out a mixture of alpha streptococcus and streptococcus milleri, haemophilus, and d. fragilis. the patient was initially treated at that time with ampicillin, gentamicin and flagyl and was subsequently changed to unasyn. after the patient's abdominal drain was removed, the patient was sent to rehabilitation. the patient completed his course of unasyn on . within the next 72 hours, the patient developed recurrent fevers while at rehabilitation. on , the patient was admitted to for investigation of recurrent right lower quadrant pain. ct scan revealed a 5.6 by 2.8 centimeter fluid pocket in his right lower quadrant. this fluid pocket communicated with the skin by a sinus tract from the prior drain. physical examination: on physical examination on admission, the vital signs were notable for a temperature of 100.1. heart rate was in the 60s. the blood pressure was 98/50. the patient was saturating 100% in room air. in general, the patient appeared weak and ill appearing. the patient's head, eyes, ears, nose and throat examination was notable for a normocephalic and atraumatic head. the extraocular movements were intact. the neck was supple without lymphadenopathy. the lung examination revealed lungs which were clear to auscultation bilaterally. cardiovascular examination revealed an irregular pulse, irregular heart sounds with a iii/vi systolic crescendo, decrescendo murmur at the right upper sternal border. abdominal examination revealed positive bowel sounds, soft, mildly distended abdomen with the right lower quadrant tenderness. the extremities showed 2+ edema bilaterally. neurologically, the patient was grossly intact. laboratory data: on admission, laboratory data was notable for a white blood cell count of 14.0. a hematocrit was 27.2. the platelet count was 229,000. the differential was 89% neutrophils and 6% lymphocytes. the sodium level was 130, potassium 3.5, chloride 93, bicarbonate 25, blood urea nitrogen 44, creatinine 1.4 and the glucose was 152. digoxin level was 1.4. urinalysis revealed trace blood, 0-2 red blood cells, white blood cells and rare bacteria. abdominal ct revealed the aforementioned 5.6 by 2.8 centimeter fluid collection in the right lower quadrant. hospital course: the patient was originally admitted to the acove service. he underwent a drainage procedure for the right lower quadrant abscess on . over the course of his hospitalization on the acove service, the patient developed acute renal failure with a rising creatinine to 2.8 with an admission value of 1.4. urinary output decreased and the patient developed increasing edema. the patient also developed episodes of bradycardia with heart rate dropping to the 30s. initially, these episodes of bradycardia were asymptomatic. however, the patient subsequently developed episodes of recurrent bradycardia with heart rate into the 20s. with these episodes, the patient became presyncopal. the episodes resolved spontaneously at least once atropine was given but the heart rate did not improve. the electrophysiology service was consulted. they recommended discontinuation of digoxin which was done. the patient developed increasing dyspnea over his hospital course. his secretions increased as did his oxygen requirement. his respiratory status improved somewhat with an increase in his lasix dosing. on the night of , the patient developed frequent pauses in his ventricular response to his atrial fibrillation lasting up to six seconds at a time. with these pauses in ventricular response, the patient was noted to have "his eyes rolling back into his head" and unresponsiveness. at that time, the electrophysiology service was reconsulted and the patient was transferred to the for transvenous pacemaker placement. a vvi pacemaker was placed externally with a temporary wire to the right ventricle. the patient was stable after pacemaker placement in the intensive care unit from the standpoint of his cardiac rhythm. the pacemaker was placed externally on the upper right chest wall and was dressed and taped in place. the patient's subsequent intensive care unit course was notable for worsening of his respiratory status. chest x-rays were notable for the appearance of probable multilobar pneumonia. the patient's p.o. intake decreased due to lack of appetite. the patient was maintained on intravenous antibiotics. permanent pacemaker implantation was deferred because of ongoing questions of infection related to his abdomen and subsequently to his multilobar pneumonia. extensive meetings with the patient and his family were held regarding the patient's wishes for continuation of intensive treatment. the patient decided that his goals for care were to return to the home, deferring more intensive in-hospital care for his multiple medical problems. the patient decided that he did not want to pursue resuscitation and was made "do not resuscitate". on further discussions with the patient regarding his prognosis, the patient determined that he wished to return home and no longer pursue in-hospital care. due to the patient's poor prognosis, hospice services were determined to be the most appropriate in home care method for the patient and his family. at the time of this dictation on , the patient is to discharge the patient home with hospice care on . discharge status: the patient will be discharged to home on , with home hospice care. discharge diagnoses: 1. intra-abdominal abscess. 2. severe aortic stenosis. 3. bradycardia and symptomatic pauses, status post vvi external pacemaker. 4. atrial fibrillation. 5. congestive heart failure. 6. pneumonia. 7. renal failure. medications on discharge: 1. morphine 5 to 20 mg q1-2hours sublingual p.r.n. pain or shortness of breath. 2. lorazepam 0.5 to 2 mg q4hours sublingual p.r.n. anxiety. 3. levsin 0.125 to 0.25 mg q4-6hours p.r.n. pulmonary edema. 4. nitroglycerin 0.4 mg sublingual p.r.n. chest pain. 5. tylenol 650 mg p.o. q4-6hours p.r.n. pain. 6. trazodone 50 mg p.o. q.h.s. p.r.n. insomnia. 7. protonix 40 mg p.o. once daily. 8. lasix 80 mg p.o. twice a day. discharge diet: the patient's discharge diet is a regular diet as tolerated. the patient will be discharged with a foley catheter for comfort. the patient's discharge services will include home hospice services. , m.d. dictated by: medquist36 procedure: percutaneous abdominal drainage initial insertion of single-chamber device, rate responsive initial insertion of transvenous lead

Answer: The patient is high likely exposed to
