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: mrs. is a 55-year-old woman who underwent coronary artery bypass graft on of this year. postoperative course was significant for atrial fibrillation and she was discharged home ultimately on . she developed shortness of breath on at home and was admitted to hospital. upon admission, the patient was noted at hospital to have bilateral pleural effusion. she ruled out for myocardial infarction. she underwent bilateral thoracentesis and continued with left loculated effusion. on the , the patient underwent a ct scan which revealed a gallbladder with some sludge, however over the next few days she developed right upper quadrant pain. her right upper quadrant ultrasound was negative, but on the hida scan was positive for cholecystitis. she was taken to the operating room on for acute cholecystitis and gallbladder was noted at that time to be gangrenous and he underwent a laparoscopic cholecystectomy at that time. over the next couple of days, the patient's distal portion of her sternal was noted to have increasing erythema. she was locally debrided at the bed side. her incision continued to have increasing erythema. she had positive blood culture at that time and positive pleural fluid for strep mutans. she was taken to the operating room at hospital on for a sternal debridement and at that time the patient was found in the operating room to have an unstable sternum and she was transferred to on for further treatment of a sternal dehiscence. medications: 1. nph insulin 18 units subcutaneous q a.m., 9 units subcutaneous q p.m. 2. tequin 400 mg intravenous qd 3. vancomycin 1 gm intravenous 4. aspirin 5. accupril past medical history: 1. coronary artery bypass graft on 2. insulin dependent diabetes 3. hypercholesterolemia 4. status post cholecystitis on previously described 5. status post laser eye surgery 6. status post sternal debridement as also previously described admission physical examination: vital signs: temperature 99.0??????, pulse 84 in normal sinus rhythm, blood pressure 130/70, oxygen saturation on room air is 94%. her respiratory rate was 25. neurologic: the patient was grossly intact, albeit anxious. respiratory: her lung sounds were diminished throughout, although clear. coronary: regular rate and rhythm. extremities: warm and dry to touch. gastrointestinal: within normal limits. chest: her sternal incision was entirely open. sternal wires are clearly visible on admission and her sternum was clearly dehisced. hospital course: a plastic surgery consultation was obtained and dr. , the plastic surgeon, was in agreement that the patient required a sternal debridement. she was taken to the operating room the following day where she underwent a debridement of her sternum as well as an omental flap and bilateral pec flaps with advancement flaps. the patient tolerated the procedure well. she was transported postoperatively from the operating room to the cardiac surgery recovery unit. she was placed on amiodarone intravenously due to some atrial fibrillation that she had previously had before going to the operating room. she was also on intravenous neo-synephrine drip due to some hypotension. she was empirically placed on levofloxacin and vancomycin antibiotics for broad spectrum coverage. on postoperative day #1, the patient was weaned from mechanical ventilator and extubated. on postoperative day #2, she continued to be hemodynamically stable and was transferred from the intensive care unit to the telemetry floor in stable condition. she was begun with rehabilitation physical therapy and began to ambulate at that time. amiodarone was converted to po. she remained in normal sinus rhythm. - drains remained in placed and her remained clean, dry and intact. the patient continued to progress well over the next few days. the final culture of the sternal tissue revealed no growth. the final culture of fluid from the revealed rare growth of alpha strep, moderate growth of coagulase negative strep of two different morphologies, however this was an abbreviated work up due to multiple bacterial types which may be attributed to a contaminant. today, postoperative day #6, the patient is hemodynamically stable and ready to be discharged home with visiting nurse assessment. her condition today is as follows: vital signs: temperature 98.9??????, pulse 74, blood pressure 116/66, respiratory rate 18, room air oxygen saturation is 93%. lungs: clear to auscultation. coronary: regular rate and rhythm. abdomen: benign. her is clean, dry and intact with bilateral - drains in place. most recent laboratory values from : magnesium 1.8, potassium 3.5, hematocrit of 25.6. th is to be discharged home today. she is to follow up with dr. on , at 9:15 on the clinical center on the . she is to follow up with dr. here and to call for an appointment to see dr. in one month. discharge condition: stable discharge diagnosis: 1. sternal dehiscence, status post sternal debridement and omental and pectoral flaps , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours local excision of lesion or tissue of bone, scapula, clavicle, and thorax [ribs and sternum] attachment of pedicle or flap graft to other sites diagnoses: pure hypercholesterolemia diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled atrial fibrillation aortocoronary bypass status 

Answer: The patient is high likely exposed to
