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 65-year-old woman status post coronary artery bypass grafting times three on and discharged home on , who the day prior to admission noted increasing redness of her right lower extremity at the saphenectomy site. she denied fevers, chills or leg pain. she had no shortness of breath and otherwise felt well. past medical history: coronary artery disease status post coronary artery bypass grafting. non-insulin-dependent diabetes mellitus. hypertension. arthritis. total abdominal hysterectomy. appendectomy. allergies: zestril. medications: lasix 20 b.i.d., potassium chloride 20 b.i.d., colace 100 b.i.d., aspirin 325 q.d., glipizide 5 q.d., lipitor 20 q.d., valsartan 60 q.d., lopressor 50 b.i.d., percocet p.r.n. physical examination: vital signs: temperature 98.4??????, heart rate 64 in sinus rhythm, blood pressure 156/43, respirations 20, oxygen saturation 98% on room air. general: well appearing in no acute distress. heent: pupils equal, round and reactive to light. extraocular movements intact. anicteric. noninjected. neck: supple. no lymphadenopathy. cardiovascular: regular, rate and rhythm. lungs: clear but with diminished breath sounds at the bases. abdomen: soft and nontender. positive bowel sounds. extremities: dopplerable pulses of both dorsalis pedis and posterior tibial bilaterally. right lower extremity with multiple areas of erythema and warmth. tender to touch along the saphenectomy site with scant serous drainage. laboratory data: white count 14.1, hematocrit 30.5, platelet count 494; sodium 136, potassium 4.9, chloride 101, co2 22, bun 21, creatinine 1.1, glucose 195. the patient at that time underwent a lower extremity ultrasound to rule out deep venous thrombosis. the exam showed no evidence of deep venous thrombosis. hospital course: the patient was admitted to ................... she was begun on vancomycin and levofloxacin for her lower extremity cellulitis. over the next two days, the patient's cellulitis improved. on hospital day #3, it was decided that she was stable and ready for discharge to home. at the time of discharge the patient's physical exam revealed her vitals signs to be stable, afebrile and alert and oriented times three. she moves all extremities. breath sounds were clear to auscultation bilaterally. heart sounds were regular, rate and rhythm. sternal incision is healing well with no erythema or purulence. abdomen soft, nontender and nondistended. extremities with no edema. right lower extremity saphenous vein graft site incision clean and dry with mild surrounding erythema decreased from the previous day with no drainage at this time. discharge medications: lasix 20 mg b.i.d., colace 100 mg b.i.d., aspirin 325 q.d., percocet tab q. p.r.n., glipizide 5 mg b.i.d., lipitor 20 mg q.d., valsartan 160 mg q.d., lopressor 50 mg b.i.d., ciprofloxacin 500 mg p.o. q.12 hours x 10 days. discharge diagnosis: 1. coronary artery disease status post coronary artery bypass grafting times three. 2. non-insulin-dependent diabetes mellitus. 3. hypertension. 4. arthritis. 5. total abdominal hysterectomy. 6. appendectomy. 7. cellulitis of the right lower extremity at saphenous vein graft site. disposition: she is to be discharged to home. follow-up: she is to have follow-up with her primary care physician in two weeks. she is to follow-up with dr. in his office four weeks from the date of her initial discharge from coronary artery bypass grafting; appointment to be made by the patient. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery (aorto)coronary bypass of two coronary arteries diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled other and unspecified hyperlipidemia 

Answer: The patient is high likely exposed to
