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 54 year old male with end-stage renal disease secondary to post-streptococcal glomerular nephritis and cpdd, and adrenal insufficiency, who presented with two to three weeks of lower abdominal pain and was found to be clostridium difficile positive. upon work-up the patient showed worsening abdominal ct scan consistent with pan-colitis. the patient was initially treated with vancomycin intravenously with p.o. ciprofloxacin and flagyl. on , the patient was found to be gasping for air while on 100% non-rebreather mask with an arterial blood gases of 7.04, 80, 43. the patient was immediately intubated and admitted to the surgical intensive care unit at which time the patient was found to have atrial fibrillation with heart rate between 100 to 140. rate was very difficult to control and diltiazem drip was initiated. on , the patient's heart rate remained between 90 to 110 with diltiazem drip at 10 mg per hour and blood pressure was also difficult to maintain. the patient responded well initially to boluses with decrease in tachycardia, however, due to the worsening pan-colitis, the patient was taken back to the operating room for a subtotal colectomy. physical examination: n/a. summary of hospital course: the patient is a 55 year old male status post subtotal colectomy and end-ileostomy for infarcted small intestine and colitis with pseudomembranes. the patient was initiated on broad-spectrum antibiotics with cultures sent. the patient's ct scan of the abdomen indicated a diffuse thickening of terminal ileum and large intestine to the transverse colon without stranding. a repeat ct scan immediately prior to the subtotal colectomy indicated pan-colitis which progressed from prior scan but no evidence of perforation. immediately postoperatively, the patient continued to have respiratory distress requiring increased pressor support and required continued transfusion with seven units both of p, two units of packed red blood cells and four liters of crystalloid. despite the continued resuscitation, the patient remained hypotensive with continued lactic acidosis requiring bicarbonate replacement. the aggressive resuscitation continued until , when after a long discussion with the family members, the patient was made comfort measures only. the patient developed a ventricular fibrillation shortly thereafter and expired later on that evening. discharge diagnoses: status post subtotal colectomy and ileostomy. disposition: death. , m.d. dictated by: medquist36 procedure: other partial resection of small intestine venous catheterization for renal dialysis permanent colostomy ileostomy, not otherwise specified diagnoses: acidosis atrial fibrillation hypertensive chronic kidney disease, unspecified, with chronic kidney disease stage v or end stage renal disease defibrination syndrome other shock without mention of trauma intestinal infection due to clostridium difficile acute vascular insufficiency of intestine 

Answer: The patient is high likely exposed to
