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 45 year old male with a past medical history of insulin dependent diabetes mellitus, now presenting with gangrene of left fourth toe which started in mid-. he was admitted to , hospital (home town), and started on intravenous antibiotics. amputation was recommended after an angiogram and mra were performed. he is now here for a second opinion. past medical history: 1. insulin dependent diabetes mellitus since with triopathy. 2. legally blind. 3. hypertension. 4. coronary artery disease status post silent myocardial infarction times two. 5. status post kidney transplant in . 6. peripheral vascular disease status post right below the knee amputation. 7. hyperlipidemia. 8. anemia. past surgical history: 1. living related kidney transplant in . 2. open cholecystectomy in . 3. right below the knee amputation. 4. left total knee replacement. medications on admission: 1. imuran 125 mg q. day. 2. lopid 600 mg twice a day. 3. asa, 325 mg q. day. 4. axid 150 mg twice a day. 5. medrol 10 mg q. day. 6. valium 5 mg twice a day. 7. duricef 500 mg twice a day. 8. toprol xl 25 mg q. day. 9. demerol 25 mg q. day p.r.n. 10. humulin n 30 units q. a.m. 11. regular insulin sliding scale. 12. epogen 8000 units subcutaneously on monday, wednesday and friday. 13. nitroglycerin spray p.r.n. 14. lasix 20 mg p.r.n. 15. captopril 25 mg three times a day. 16. phenergan p.r.n. 17. iron sulfate 325 mg three times a day. 18. colace 100 mg twice a day. 19. neurontin 300 mg p.o. q. h.s. allergies: shrimp and iodine. hospital course: mr. was admitted under the vascular surgery service. he was started on antibiotics. an angiogram was performed which revealed high-grade stenosis of the tibial peroneal trunk with two-vessel anterior tibial and posterior tibial runoff below that includes feeding into posterior tibial and dorsalis pedis artery. consult was obtained to optimize diabetic management. renal, podiatry and cardiology consults were also obtained. he underwent a cardiac catheterization on , per cardiology recommendation which revealed three-vessel disease. coronary artery bypass surgery was recommended prior to the vascular surgery. he underwent coronary artery bypass graft times two (saphenous vein graft to left anterior descending, saphenous vein graft to distal right coronary artery), on . his postoperative course was routine. he then underwent a left below the knee amputation on . he tolerated the procedure well. his postoperative course was again routine. he was transiently hypotensive on postoperative day two, although he was asymptomatic. he responded to a fluid bolus. he normally runs with systolic blood pressure of around 85 to 95 mm of mercury. he is now ready to go to rehabilitation. medications on discharge: 1. insulin 22 units subcutaneously a.m. and 6 units subcutaneously p.m. 2. regular insulin sliding scale. 3. levaquin 500 mg p.o. q. day. 4. lopid 600 mg p.o. twice a day. 5. medrol 10 mg p.o. q. day. 6. imuran 125 mg p.o. q. day. 7. asa 325 mg p.o. q. day. 8. lopressor 15 mg p.o. twice a day. 9. colace 100 mg p.o. twice a day. discharge instructions: 1. the patient may not weight bear on upper extremities for up to five weeks due to recent coronary artery bypass graft. 2. he may be fitted for prosthesis to the right stump. 3. he may get out of bed with maximum assistance. 4. follow-up with dr. in two weeks. discharge diagnoses: 1. non-healing ulcer, left foot, status post left below the knee amputation. 2. coronary artery disease, status post coronary artery bypass graft. , m.d. dictated by: medquist36 procedure: extracorporeal circulation auxiliary to open heart surgery coronary arteriography using two catheters (aorto)coronary bypass of two coronary arteries left heart cardiac catheterization diagnostic ultrasound of heart arteriography of femoral and other lower extremity arteries other amputation below knee diagnoses: coronary atherosclerosis of native coronary artery unspecified essential hypertension acute posthemorrhagic anemia old myocardial infarction atherosclerosis of native arteries of the extremities with gangrene below knee amputation status diabetes with peripheral circulatory disorders, type i [juvenile type], not stated as uncontrolled kidney replaced by transplant profound impairment, both eyes, impairment level not further specified 

Answer: The patient is high likely exposed to
