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: this is an 84-year-old male with history of coronary artery disease and diabetes, paroxysmal atrial fibrillation, who presented with left lower extremity redness and swelling with pain. he has had a chronic swelling and intermittent left lower extremity pain for months, but the erythema is new. he started with a spot on his medial calf last evening and progressed to diffuse very tender erythema with petechiae in the entire left leg. he is able to walk with severe pain. he denies any trauma. he has no fevers, chills, night sweats, chest pain, anginal equivalent, pnd, or orthopnea. he may have accidentally kicked the furniture with his leg. he has no respiratory or gi complaints. past medical history: 1. coronary artery disease status post three vessel cabg in . exercise treadmill test in ' showed severe apical inferior reversible defects, an ef of 46%. 2. history of gi bleed secondary to peptic ulcer disease. 3. prostate cancer status post xrt complicated by rectal bleeding. 4. paroxysmal atrial fibrillation without anticoagulation due to gi bleed. 5. fatty liver by ultrasound with normal lfts in . allergies: 1. aspirin - gi bleed. 2. penicillin - rash. 3. erythromycin, biaxin, and sulfa - unknown reactions. medications: 1. digoxin 0.25 q.d. 2. toprol xl 100 q.d. 3. lasix 40 q.d. 4. aldactone 25 q.d. 5. glyburide 2.5 q.d. 6. lipitor 5 q.d. 7. zantac 75 h.s. 8. tylenol. 9. sublingual nitroglycerin prn. social history: he is married and lives with his wife. quit tobacco 35 years ago. he does not drink. family history: shows that the mother had coronary artery disease at 74 and father had coronary artery disease. physical examination: patient's physical exam showed temperature of 94 in ed triage rising to 96 on admission to the ed, pulse of 79, blood pressure 105/33, respiratory rate of 23, and sat of 96% on room air. blood sugar was 196. in general, he was in no distress. he was anicteric. heent examination was otherwise negative. he had no jvd, no lymphadenopathy. his lungs had crackles of the way up. he had a normal s1, s2 and a holosystolic murmur. abdomen was soft, nontender, tympanitic. right lower extremity showed increased edema. left lower extremity showed marked erythema with petechiae, pain, no lesions were seen as a portal for cellulitis. laboratories on admission: white count of 16.2 with 79 neutrophils and 17 bands, a hematocrit of 43.7, 225 platelets. chem-7 was notable for creatinine of 1.4, up from 1.3 at baseline, lactate was 4.1, glucose was 222. abg showed ph of 7.43, co2 of 27, and oxygen of 109. because of the patient's vital signs, and his bandemia, and elevated lactate, he was admitted to the icu for sepsis protocol. he was initially treated with cipro and clindamycin before blood cultures were performed, and he was given several liters of fluid in the ed for blood pressure that dropped to 95 with a heart rate of 50s-60s while he was beta blocked. the initial concern was for necrotizing fasciitis. he was evaluated by surgery, who felt that he would not need emergent debridement, but he was monitored for decompensation, which did not occur. he had a ct of his leg which showed no free air. vancomycin was initially added for concern for mrsa. this was later discontinued and he was kept on clindamycin and cipro alone. patient was oxygenating well despite his chf on examination, and he was given only gentle fluids initially. he was followed by surgery in the icu. his cellulitis improved on antibiotics of cefazolin and cipro. he was continued on his routine heart failure medications. he was felt to be hypovolemic despite his crackles and was given more iv fluid repletion due to his picture of sepsis. he remained hemodynamically stable, and was transferred to the floor on the 16th. the only notable events in the icu were a new t-wave inversion in v2 and v3 and a peak ck of 369 with a troponin of 0.6 felt to be consistent with demand ischemia. on the floor, he continued his antibiotics, and his cellulitis continued to be improving. he was seen by physical therapy, who cleared him for discharge home. however, he had worsening diarrhea. clostridium difficile was sent and was negative. he, however, had difficulty with worsening chf on the evening of the 17th and 18th. his diuresis was increased requiring 40 b.i.d. iv lasix. he had repeat ekg and troponins, which were negative for new ischemia at that time. the cause of his chf exacerbation was felt to be the fluids he received for diarrhea and for sepsis originally. he was given a slightly lower dose of his beta blocker, and continued on his statin, and digoxin, and aldactone. patient was seen by occupational therapy, who felt that he had a borderline requirement for rehab stay, however, given his relatively tenuous chf status and medication balancing, he was felt to be someone who would benefit from a short rehab stay, which was arranged for . discharge diagnoses: 1. left lower extremity cellulitis complicated by sepsis and mild hypotension. 2. congestive heart failure due to volume overload. 3. history of gi bleed preventing aspirin and anticoagulation use. discharge condition: will be updated on the time of his departure on the 20th. discharge medications: 1. ipratropium nebulizers or mdis q.4h. prn. 2. albuterol nebulizer or mdi q.4h. prn. 3. metoprolol xl 50 q.d. 4. losartan 25 q.d. 5. guaifenesin ml p.o. q.6h. prn. 6. spironolactone 25 q.d. 7. glyburide 2.5 mg p.o. q.d. 8. cefazolin 1 gram iv q.12h. to be converted to a 14 day total duration of antibiotics with keflex on departure from acute rehab. 9. digoxin 0.25 mg p.o. q.d. 10. ciprofloxacin 500 mg p.o. b.i.d. 11. protonix 40 mg q.d. 12. lipitor 5 mg p.o. q.h.s. 13. lasix dose to be determined but likely 80 mg b.i.d. follow-up instructions: followup should be with dr. and the patient's cardiologist. patient's daily weight must be monitored and his lasix may need to be increased if his weight increases. saturations must also be closely followed with his respiratory rate and physical exam. he should consume a 2-gram sodium cardiac diet. discharge status: full code, but this spares clarification with the patient. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified diagnoses: congestive heart failure, unspecified acute kidney failure, unspecified unspecified septicemia atrial fibrillation coronary atherosclerosis of unspecified type of vessel, native or graft aortocoronary bypass status cellulitis and abscess of leg, except foot acute on chronic systolic heart failure 

Answer: The patient is high likely exposed to
