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: allergies: morphine sulfate attending: chief complaint: septic shock toxic c. diff s/p subtotal colectomy major surgical or invasive procedure: invasive monitoring history of present illness: pt is 73yo male who was recently diagnosed with lyme myelitis and was hospitalized. he was treated with ceftriaxone and discharged home. at home, he developed watery diarrhea for several weeks and became severely dehydrated. he presented to osh and was found to have c diff toxic megacolon. on , he was taken to the or by an outside surgeon and underwent subtotal colectomy and end ileostomy. pt's postop condition was moribund, with oliguria, in septic shock, and he was transferred to for further management. past medical history: spinal stenosis cad, s/p cabg & rca stent recurrent 3 vessel coronary disease hypercholesterolemia htxn prostate ca, s/p xrt hx of pancreatitis barrett's esophagus / gastritis social history: unable to obtain from patient family history: unable to obtain from patient physical exam: vs unstable, while on pressors intubated, sedated perrl, nonicteric sclera supple neck rr s1 s2 tachycardic course breath sounds bilaterally with ronchi in lower lobes soft mildly distended, no guarding or rebound, pink ostomy right lower quadrant, retention sutures and staples, no significant drainage, no erythema ext with bilateral 2+ pitting edema, mottled to thigh bilaterally pertinent results: 03:48pm wbc-32.1*# rbc-3.23* hgb-9.9* hct-30.3* mcv-94 mch-30.7 mchc-32.7 rdw-14.9 03:48pm plt smr-very low plt count-53*# 03:48pm pt-14.1* ptt-59.2* inr(pt)-1.3 03:48pm fibrinoge-596* 03:48pm glucose-138* urea n-37* creat-2.3*# sodium-139 potassium-4.9 chloride-116* total co2-16* anion gap-12 03:48pm alt(sgpt)-72* ast(sgot)-208* ld(ldh)-812* ck(cpk)-2376* alk phos-61 amylase-79 tot bili-0.2 03:48pm lipase-17 03:48pm ck-mb-38* mb indx-1.6 ctropnt-0.15* 03:48pm albumin-1.1* calcium-6.1* phosphate-5.4* magnesium-1.7 04:15pm type-art po2-68* pco2-43 ph-7.15* total co2-16* base xs--13 04:15pm lactate-3.0* brief hospital course: mr. arrived on a ventilator and was aggressively resuscitated using invasive monitoring. he was given intravenous boluses, transfused blood products and was placed on four pressors: levophed, neo-synephrine, dobutamine, and pitressin. (later, pt was also placed on epinephrine gtt as well.) pt arrived with a swan catheter, and cardiac parameters were hyperdynamic. given the pt's cardiac hx and mildly elevated cardiac enzyme, a stat cardiology consult was obtained. stat tte showed preserved ef and no grossly abnormal wall motions. there was no pericardial effusion. all these findings essentially ruled out cardiogenic shock. pt arrived anuric to . pt was acidodic as well. pt was started on sodium bicarbonate gtt. nephrology consult was obtained. l femoral dialysis line was placed, and pt was initiated on cvvh. lft's began to rise, indicating likely shock liver. presuming septic shock, pt was given broad spectrum iv antibiotics. given the severity of the shock, he was also started on activated protein c gtt. despite all these measures, pt required increasingly higher doses of all the pressors to maintain bp. serum lactic acid level peaked to > 10. ventilation was difficult, requiring fio2 of 1.0 and high peep. family members were present and understood the critical state of pt's multi-organ failure. when pt's blood pressure could not be maintained, family members decided to make the pt dnr. slowly, pt became bradycardic and hypotensive. cardiac arrest ensued. pt was pronounced deceased 4:45am, . cause of death was cardiopulmonary arrest due to septic shock. discharge medications: none discharge disposition: expired discharge diagnosis: c.diff collitis s/p subtotal colectomy, ileostomy acute renal failure acute respiratory failure post operative anemia liver failure hypokelimia hypocalcemia hypomagnesimia cad discharge condition: expired discharge instructions: expired followup instructions: expired procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours hemodialysis venous catheterization for renal dialysis transfusion of packed cells infusion of drotrecogin alfa (activated) infusion of vasopressor agent diagnoses: hypocalcemia anemia, unspecified pure hypercholesterolemia unspecified essential hypertension acute posthemorrhagic anemia acute kidney failure, unspecified unspecified septicemia severe sepsis personal history of malignant neoplasm of prostate coronary atherosclerosis of unspecified type of vessel, native or graft aortocoronary bypass status percutaneous transluminal coronary angioplasty status hypopotassemia acute respiratory failure septic shock intestinal infection due to clostridium difficile other sequelae of chronic liver disease disorders of magnesium metabolism mixed acid-base balance disorder acquired absence of intestine (large) (small) 

Answer: The patient is high likely exposed to
