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 70 year-old male admitted to the micu with sepsis, hypertension, status post episode of ventricular tachycardia now on pressors. the patient was admitted to the vascular service between and . he has an extensive history of peripheral vascular disease and status post left femoral popliteal bypass with a jump graft and a left second toe amputation and revision. the patient was found to have a gangrenous wound with involvement of the left third toe with purulent discharge and breakdown of the incision site and underwent further debridement and revision. he was evaluated by his vascular surgeon dr. and thought to be stable for rehab and that the wound was viable and without need for further surgical intervention. the patient was at rehab when he started complaining of difficulty swallowing and coughing up dried blood on and neck pain. rehab doctor was called to evaluate the patient for same complaints and blood pressure was noted to be 70/40 with a heart rate of 92, white count 33.6. blood cultures from had four out of four bottles growing gram positive cocci while on vancomycin and levaquin and the patient was febrile to 102. the patient was transferred to , but on route developed ventricular tachycardia while on dopamine and was diverted to . apparently ventricular tachycardia spontaneously resolved and the patient was stable in their emergency department and he was sent to emergency department while awaiting micu bed. in the emergency department here his blood pressure was 60/palp. the patient was started on neo-synephrine, fluid boluses and flagyl was added to his antibiotic regimen. past medical history: coronary artery disease status post myocardial infarction in , status post coronary artery bypass graft in , status post catheterization in with patent left internal mammary coronary artery to left anterior descending coronary artery, patent supraventricular tachycardia to obtuse marginal two and occluded saphenous vein graft to right coronary artery. exercise mibi on showed fixed apical defects, severe fixed distal anterior wall defect with minimal reversible defect in distal inferior wall, global left ventricular hypokinesis and apical akinesis, ef of 22%. paroxysmal atrial fibrillation, type 2 diabetes, end stage renal disease on hemodialysis since , hypercholesterolemia, renal cell carcinoma status post right nephrectomy in with metastasis to bone treated with radiation therapy in with metastasis to gallbladder status post cholecystectomy and status post abdominal wall dissection. hypothyroidism, peripheral vascular disease status post above surgeries. medications: colace, nephrocaps, lopressor 12.5 b.i.d., amiodarone 200 q day, synthroid 100 micrograms q day, pepcid 20 mg q day, senna, vitamin c, levaquin 250 mg po after hemodialysis. zocor 40 q.d., nph 16 units in the a.m. and 3 units in the p.m. calcitriol, reglan, zinc, aspirin, coumadin 1 mg po q day, vancomycin dose with hemodialysis. allergies: ativan makes the patient "go crazy." social history: no tobacco. rare alcohol. physical examination: vital signs 60/palp increased to 97/36 on neo-synephrine. pulse 97. respiratory rate 22. sating 98% on 2 liters nasal cannula. in general the patient is in bed in no acute distress. heent oropharynx clear. sclera anicteric. neck mildly swollen and full, nontender, no lymphadenopathy. no jvd. lungs with decreased breath sounds at the bases. cardiovascular irregular irregular rhythm. normal s1 and s2. abdomen was soft, nontender, nondistended with normoactive bowel sounds. extremities left lower extremity with tma frankly necrotic, but no purulence. initial data: white blood cell count 27.6 with 97% neutrophils, 3 lymphocytes, 3 monocytes, hematocrit 29.5, platelets 537, inr 3.1, liver function tests within normal limits. chem 7 143, 4.8, 106, 23, 29, 4.2, glucose 73. initial ck negative. rhythm strip with sustained ventricular tachycardia. electrocardiogram subsequently showed atrial fibrillation rate of 97, q waves in 3 and v1, poor r wave progression, no st or t wave changes, unchanged from . chest x-ray showed possible right lower lobe infiltrate with obscured right hemidiaphragm. ct of the neck showed degenerative changes of the cervical spine, but no pharyngeal fluid collections. hospital course: 1. vascular surgery evaluated the patient and they determined when the patient was medically stable that he would require bilateral below the knee amputations. in the interim the patient's left tma wound received bedside debridement. 2. the patient was also complaining of new onset right sided blindness. ophthalmology evaluated the patient in the emergency department. there is no evidence of septic emboli. the patient's blindness was consistent with aion. 3. the patient was also seen by the infectious disease service for his staph aureus bacteremia, which is likely secondary to his gangrenous foot. other sources of infection could hve included his dialysis catheter. the patient was continued on vancomycin and ciprofloxacin as well as flagyl. 4. cardiovascular, the patient continued to be persistently hypotensive. he was started on neo-synephrine to which levophed was also added. the patient also started to become dyspneic for which he was intubated. immediately after his intubation the patient became increasingly hypotensive and also had an episode of ventricular tachycardia and also had several episodes of supraventricular tachycardia. both of his arrhythmias resolved spontaneously. the patient also had a metabolic acidosis, which was being poorly compensated. at that time a family meeting was held and the gravity of his situation was explained. on the patient's family decided to withdraw care. the patient was extubated and started on a morphine drip and the patient expired shortly thereafter. the time of death was 7:30 p.m. on . cause of death: respiratory failure secondary to sepsis. no postmortem was performed. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours insertion of endotracheal tube hemodialysis nonexcisional debridement of wound, infection or burn diagnoses: pneumonia, organism unspecified esophageal reflux atrial fibrillation methicillin susceptible

Answer: The patient is high likely exposed to
