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: allergies: sulfa (sulfonamides) / iodine; iodine containing / cephalexin / celecoxib / rofecoxib / lisinopril / methylene blue attending: chief complaint: infected necrotic ulcers of the right lower extremity. major surgical or invasive procedure: 11/23/9 debridement of infected necrotic right extremity ulcers. 11/30/9 right above-knee amputation history of present illness: 81-year-old woman with history of severe peripheral arterial disease, who had previously presented with acute limb ischemia and she has subsequently underwent endovascular revascularization of the right lower extremity with stent of the right superficial femoral artery, balloon angioplasty of right superficial femoral artery in-stent stenosis and angiojet thrombectomy of the right superficial femoral artery, popliteal artery, and tibioperoneal trunk. despite revascularization she was not able to heal the right lower extremity and therefore developed significant gangrene of the right leg with necrotic ulcers on the posterior calf. she was admitted for iv antibiotics, wound care and possible debridement in the or. past medical history: pmh: dm 2, afib, cdiff colitis, cad, gout, depression, dialstolic chf, chronic angina (afib), : group b strep bacteremia, ra (prednisone), osteopenia, carpal tunnel. psh: : angioplasty and stent right sfa : ballon angioplasty and full-lenght stent right sfa : balloon angioplasty of right sfa in-stent stenosis and angiojet thrombectomy of the right superficial femoral artery, popliteal artery, and tibioperoneal trunk. : cabg x 4 hernia repair social history: non drinker non smoker family history: unknown physical exam: physical exam neuro/psych: oriented x3, affect normal, nad. neck: no masses, trachea midline, thyroid normal size, non-tender, no masses or nodules, no right carotid bruit, no left carotid bruit. nodes: no clavicular/cervical adenopathy, no inguinal adenopathy. skin: no atypical lesions. heart: regular rate and rhythm. lungs: clear, normal respiratory effort. gastrointestinal: non distended, no masses, guarding or rebound, no hepatosplenomegally, no hernia, no aaa. rectal: not examined. extremities: no popiteal aneurysm, no femoral bruit/thrill, no varicosities, abnormal: b/l le edema. pulse exam (p=palpation, d=dopplerable, n=none) rue radial: p. ulnar: p. brachial: p. lue radial: p. ulnar: p. brachial: p. rle femoral: p. dp: d. pt: d. lle femoral: p. dp: d. pt: d. pertinent results: 12:05pm wbc-10.8 rbc-3.66* hgb-10.7* hct-34.7* mcv-95 mch-29.3 mchc-30.9* rdw-17.0* 12:05pm plt count-530* 12:05pm glucose-81 urea n-14 creat-0.5 sodium-143 potassium-3.9 chloride-99 total co2-34* anion gap-14 12:05pm calcium-7.7* phosphate-3.3 magnesium-1.6 12:05pm pt-31.5* inr(pt)-3.2* brief hospital course: patient was admitted on with multiple necrotic infected ulcers after undergoing revascularization of her right leg chronic ischemia. she was started on iv antibiotics, wound care and underwent debridement of these necrotic infected ulcers on /9. she has failed a course of antibiotics and nonoperative treatment, therefore patient was consented for a right above-knee amputation. as a result of her multiple high-risk comorbidities, postoperatively she developed acute renal failure, a.fib with rvr and sepsis. cardiology was consulted and measures to keep her chronic atrial fibrillation with adequate hr were made. nephrology was also involved and hd was suggested as a possible therapy for her uremia. on /9 patient significant abdominal distention with ?colonic pseudo-obstruction, ct scan consistent with disease and hemodynamic compromise on /9. no free air or fluid, no bowel wall edema, mesenteric or portal venous air were seen. ngt and rectal tubes were placed. gi and general surgery were consulted. she was then transferred from the vicu to the intensive care unit. after extensive conversations with the family and son -
