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: eighty-year-old male admitted for nausea, vomiting, and diarrhea. apparently had been on augmentin in the past for foot infection. upon arrival to the ed found to be hypotensive, but responding to iv fluids. started on vancomycin, levofloxacin, and flagyl. admitted to the floor, where he had a relatively uncomplicated course for the first few days. stool came back positive for clostridium difficile and he was treated for that. on p.m., patient became acutely confused and had declining mental status. gas drawn at the time revealed a ph of 7.17 believed to be related to metabolic acidosis. also found to be hypotensive at the same time. he was intubated for continued respiratory acidosis. was started on dopamine and transferred to the intensive care unit. past medical history: 1. cad status post cabg. 2. ischemic cardiomyopathy with an ef of 20-30% with severe mr. 3. dual lead pacemaker. 4. chronic renal failure. 5. right hip repair in of this year. 6. left cataract surgery. medications upon transfer: 1. levofloxacin 250 p.o. q.d. 2. vancomycin 500 mg q 4 hours. 3. zofran. 4. bumex 2 p.o. b.i.d. 5. senna. 6. colace. 7. atrovent. 8. albuterol. 9. digoxin 0.25 monday and friday. 10. metoprolol. 11. flagyl 500 p.o. t.i.d. 12. trazodone. 13. zocor. 14. flomax. 15. enalapril 10 mg p.o. q.d. 16. neurontin 300 mg p.o. q.d. 17. lopressor 12.5 mg p.o. b.i.d. physical exam upon arrival to the icu: weight 57 kg. temperature 98. blood pressure 120/40. heart rate of 80. general: sedated and intubated. fair air movement with crackles throughout. unable to appreciate jvd. s1, s2, holosystolic murmur. abdomen is soft, nontender, and nondistended, normoactive bowel sounds. extremities reveal profound anasarca. laboratories on admission: significant for a white count of 11.2, hemoglobin 31, platelets 150, creatinine of 2.8. brief hospital course: patient is admitted to the intensive care unit in the context of hypotension, metabolic acidosis. this was believed to be due to an overwhelming infection and he was volume resuscitated. however, continuing volume resuscitation, probably led to worsening of his congestive heart failure. his creatinine continued to rise leading to a value of 3.0. he was eventually extubated, and was able to maintain decent oxygenation. on the night of , the patient developed new episodes of hypotension. at the same time, his sputum was growing staphylococcus aureus. he was on broad-spectrum antibiotics throughout hospital stay including vancomycin, ceftazidime, levofloxacin, and flagyl. patient initially responded to dopamine, but as the day progressed and particularly , he had continuous episodes of hypotension not responding to iv fluids. he was started on dopamine as well as norepinephrine with very minimal effect. at this point, he suffered an asystolic arrest, and despite resuscitative efforts, he expired around 10 a.m. on . dr., 12-981 dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified insertion of endotracheal tube excisional debridement of wound, infection, or burn diagnoses: subendocardial infarction, initial episode of care mitral valve disorders congestive heart failure, unspecified unspecified septicemia intestinal infection due to clostridium difficile acute on chronic systolic heart failure mixed acid-base balance disorder 

Answer: The patient is high likely exposed to
