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 58-year-old male with history of peripheral vascular disease, status post right aka in after failed right fem distal (for revisions for thrombosis). the patient had a prolonged course at rehab and was recently admitted to on for black discoloration mra with right femoral occlusion and mild dehydration according to the primary care physician and was to get vascular follow-up. the patient then developed nausea and vomiting and fevers, called pcp and pcp referred to on . past medical history: peripheral vascular disease, status post multiple revisions, failed femoral distal bypass, history of hyperglycemia, diet controlled. coronary artery disease, status post cabg in . current medications: 1. bisoprolol 2. plavix 3. aspirin 4. oxycontin or oxycodone 5. vytoran 6. neurontin 7. klonopin 8. flomax 9. micro k allergies: no known drug allergies. social history: used tobacco, the patient is a heavy smoker. physical examination: on admission the patient was 99.1, 93, 116/76, 16 and 100% on room air. generally he is in no acute distress, cachectic. cardiovascular: regular rate and rhythm. chest is decreased breath sounds. abdomen was soft, nontender, nondistended. extremities: left lower extremity had some rubor pallor edema to mid-shin, small 2 cm ulceration on the medial malleolus with dry eschar. right lower extremity is right stump with dry gangrene, no evidence of erythema or edema. pulses: right femoral is nonphasic, popliteal, dorsalis pedis, posterior tibial, at peroneal obviously were all gone because of the amputation on the left and biphasic femoral monophasic, popliteal, dorsalis pedis and biphasic pt. laboratory findings: on admission was white count 6.6, crit 34, platelets 237. chemistry: sodium 139, potassium 4.5, chloride 100, bicarbonate 28, bun 6, creatinine .5. glucose 128, pt 113, ptt 31.8, inr 1.2. the patient was admitted to medicine and placed on iv fluids, blood cultures were drawn. the patient underwent cardiac workup, he had pain control and left ulcer was debrided. right ak stump was also debrided. the patient was admitted to the medicine service and hospital course was as follows. the patient had a cardiac evaluation hospital day 2 that showed stress electrocardiogram and echocardiogram with acute myocardial infarction unlikely since electrocardiogram showed no st elevation but maybe some chronic ischemia because troponin was somewhat elevated. the patient was kept on aspirin and placed on plavix to hold prior to surgery. by hospital day 2 the patient's nausea and vomiting had resolved. on the patient had gastrointestinal follow- up because the patient started having some melanotic stools. the patient had dropped a crit from 34 to 29, placed into the intensive care unit and they were planning to do an egd when the patient was stable. angio was held. the patient was hypotensive during this and on was transferred to the micu. on the patient had ct scan of the abdomen that showed colonic intussusception at the level of hepatic flexure with large cecal mass, pneumonia within the right upper lobe and fatty liver and chronic pancreatitis. the patient also had emphysematous changes of the periphery, bilateral lung fields, small bilateral pleural effusions and moderate intra- abdominal free fluid. because of this finding general surgery was consulted. the gastroenterologists strongly felt that the intussusception was the etiology of the patient's g.i. bleed and did not feel a preoperative colonoscopy was required. the patient was taken to the operating room for exploratory laparotomy to evaluate and possibly was done under general endotracheal anesthesia. however, no intussusception (felt to have reduced spontaneously) nor bowel mass was found and in this malnourished patient with thin bowel, it was felt best not to do an intraoperative colonoscopy (right sided lesion likely) nor resection. the patientwas taken back to the icu where he remained stable and did well postoperatively. on the patient was transferred to the floor, ng tube was discontinued on the 16th,postoperative day three. physical therapy continued to see the patient throughout and deemed him to need rehabilitative care. the patient was transferred back to the surgical intensive care unit on for respiratory distress and was intubated on . on , postop day four, lopressor was changed to intravenous. the patient was attempted to wean to extubate, was kept in negative liter and was transfused one unit of packed cells. however, he failed extubation time two and then on postoperative day seven had a bronchoscopy which was negative for any pathology or gross secretions. tube feeds were started on and up to goal on . thoracic surgery was consulted on and the patient had failed extubation twice and then self-extubated the third time and failed that as well so he had a trach placed on . did well from the trach. on postoperative day 7, the patient continued to do well, weaned off of the vent, some trach mask for most of and . however, had some episodes of hypernatremia for which was treated with free water boluses. the patient was transferred to rehabilitation center on in good health, stable on tube feeds and on trach mask. the patient was doing well and was instructed to follow-up with dr. in follow-up, he should call for an appointment. discharge diagnosis: 1. peripheral vascular disease 2. respiratory distress 3. status post negative exploratory laparotomy for intussusception. 4. status post tracheostomy. discharge medications: 1. lopressor 50 mg p.o. twice a day 2. percocet elixir. 3. albuterol 4. plavix 5. aspirin 6. tylenol 7. prevacid 8. colace 9. milk of magnesia 10. atrovent 11. insulin sliding scale 12. heparin subcutaneously 13. zinc sulfate 14. multivitamins 15. pepane area spray 16. lipitor 17. azinamide. patient's condition is good. , dictated by: medquist36 d:

Answer: The patient is high likely exposed to
