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 69-year-old gentleman with a past medical history significant for longstanding diabetes mellitus, coronary artery disease, and peripheral vascular disease who had been followed by dr. for a painful nonhealing ulceration in the medial aspect of his right fifth toe. the patient had been treated for this ulceration with a combination of saline and topical antibiotic ointments. he was referred to dr. from dr. the department of podiatry. the patient had an arteriogram performed to evaluate his peripheral vascular disease. this demonstrated patent aortoiliac, femoral, and popliteal vessels. the trifurcation was occluded with reconstitution of he proximal peroneal artery. therefore, the patient was to be admitted for an elective right below-knee popliteal to peroneal artery bypass graft. however, the patient developed a progressively worsening foot pain, redness, swelling, and cyanosis of the foot at the right fifth toe. therefore, he came to the emergency department at this institution two days prior to his elective surgery. the patient denied fevers, chills, nausea, vomiting, chest pain, shortness of breath, abdominal pain, and back pain. he reports claudication at approximately yards to 200 yards which has been persistent for the last two to three years. therefore, he was admitted for antibiotics and pain control prior to his surgery. past medical history: 1. insulin-dependent diabetes mellitus. 2. coronary artery disease; status post coronary artery bypass graft. 3. hypertension. 4. congestive heart failure. 5. hypercholesterolemia. 6. peripheral vascular disease. past surgical history: 1. status post coronary artery bypass graft in . 2. status post left carotid endarterectomy. 3. status post cataract surgery. 4. status post left knee arthroscopy. medications on admission: 1. captopril 100 mg by mouth three times per day 2. humalog 20 units subcutaneously at 7 a.m. and 18 units subcutaneously at 12 p.m. and 16 units subcutaneously at 6:30 p.m. 3. lantus 40 units subcutaneously at hour of sleep. 4. protonix 40 mg by mouth once per day. 5. levoxyl 100 mcg by mouth once per day. 6. lasix 40 mg by mouth once per day. 7. aspirin 81 mg by mouth once per day. 8. lipitor 10 mg by mouth once per day. 9. multivitamin one tablet by mouth once per day. allergies: sulfa. physical examination on presentation: physical examination revealed the patient was afebrile with a blood pressure of 150/70. the patient was alert and oriented times three and appeared healthy. in no apparent distress. neck examination revealed a left surgical scar with a bruit on the right. no masses. head, eyes, ears, nose, and throat examination revealed the oropharynx was clear. the mucous membranes were moist. heart was regular in rate and rhythm. the lungs were clear to auscultation bilaterally. the abdomen was soft, nontender, and nondistended. extremity examination revealed right foot erythema with an ulceration on the medial aspect of the fifth right toe which probed to bone. there were bilateral saphenous vein graft harvest scars. vascular examination demonstrated palpable femoral, radial, and popliteal pulses bilaterally. there were dopplerable pulses in the dorsalis pedis and posterior tibialis arteries bilaterally. pertinent laboratory values on presentation: the patient's white blood cell count was 14.2, his hematocrit was 41, and his platelet count was 262. the patient's partial thromboplastin time was 26.9 and his inr was 1.1. the potassium was 4.9. his blood urea nitrogen was 27. his creatinine was 1. pertinent radiology/imaging: a chest x-ray revealed a small right pleural effusion. electrocardiogram did not reveal any ischemic changes and was consistent with prior studies. vein mapping of the bilateral upper and lower extremities as part of his preoperative workup revealed patent lesser saphenous, cephalic, and basilic veins bilaterally. the greater saphenous veins were absent and had been used for his coronary artery bypass graft surgery. concise summary of hospital course by issue/system: the patient was admitted under the care of dr. and was started on antibiotics including vancomycin, levofloxacin, and metronidazole. the patient was maintained on bed rest with dry dressing changes and antibiotics until hospital day three. at this time, the patient was taken to the operating room where a right below-knee popliteal to peroneal bypass graft using a left cephalic vein was performed. the cardiology service was consulted prior to surgery and recommended perioperative beta blockade. this was implemented, and the patient tolerated his surgery well without complications. postoperatively, the patient was discharged to the vascular intensive care unit for close monitoring. postoperatively,, the patient had a dopplerable dorsalis pedis and posterior tibialis pulses on the right with a warm right foot. the patient was maintained on antibiotics and was transferred to the hospital floor on day one. at this time, it was decided that the patient's right fifth toe ulceration would not likely heal despite his recent surgery. therefore, he was scheduled for a right fifth toe amputation. this surgery was performed on . the procedure was performed using local anesthesia, and the patient was discharged to the regular hospital floor in good condition. postoperatively, the patient's antibiotic regimen was changed to oxacillin, levofloxacin, and flagyl. he remained on bed rest until day five following his bypass graft and day two following his toe amputation. the remainder of his course was uneventful. his antibiotic regimen was converted to dicloxacillin, levofloxacin, and flagyl on day days five and two. with the assistance of physical therapy, the patient progressed to heel touch weightbearing on the right lower extremity with right lower extremity elevation while in bed. he was discharged to home with a visiting nurse days seven and four. the patient was sent home on clindamycin and levofloxacin for approximately two weeks. he was to have visiting nurse services to assist with physical therapy and wound care. condition at discharge: condition on discharge was good. discharge status: the patient was discharged to home with visiting nurse services for wound care and physical therapy. discharge diagnoses: 1. insulin-dependent diabetes mellitus. 2. coronary artery disease; status post coronary artery bypass graft. 3. hypertension. 4. congestive heart failure. 5. hypercholesterolemia. 6. peripheral vascular disease. 7. status post left carotid endarterectomy. 8. status post right below-knee popliteal to peroneal bypass graft. 9. status post right fifth toe amputation. medications on discharge: 1. percocet 5/325-mg tablets one to two tablets by mouth q.4-6h. as needed (for pain). 2. protonix 40 mg by mouth once per day. 3. levoxyl 100 mcg by mouth once per day. 4. aspirin 81 mg by mouth once per day. 5. colace 100 mg by mouth twice per day. 6. captopril 100 mg by mouth three times per day. 7. lipitor 10 mg by mouth once per day. 8. lasix 40 mg by mouth once per day. 9. lantus 40 units subcutaneously at hour of sleep. 10. clindamycin 300 mg by mouth q.6h. (times two weeks). 11. levofloxacin 500 mg by mouth once per day (times two weeks). 12. humalog 20 units subcutaneously at 7 a.m. and 18 units subcutaneously at 12 p.m. and 16 units subcutaneously at 6:30 p.m. discharge instructions/followup: 1. the patient was instructed to follow up with dr. in approximately one to two weeks for wound evaluation. 2. the patient was instructed to follow up sooner if he developed fevers, chills, vomiting, or severe leg/foot pain. , m.d. dictated by: medquist36 procedure: amputation of toe other (peripheral) vascular shunt or bypass diagnoses: congestive heart failure, unspecified unspecified essential hypertension coronary atherosclerosis of unspecified type of vessel, native or graft polyneuropathy in diabetes ulcer of other part of foot other and unspecified hyperlipidemia methicillin susceptible staphylococcus aureus in conditions classified elsewhere and of unspecified site atherosclerosis of native arteries of the extremities with gangrene diabetes with neurological manifestations, type i [juvenile type], not stated as uncontrolled 

Answer: The patient is high likely exposed to
