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: heparin agents / penicillins / iodine containing agents classifier attending: chief complaint: transferred from after presenting with altered mental status major surgical or invasive procedure: none history of present illness: the pt is an 81m w/ cad, hypercholesterolemia, who was brought to by his son for altered mental status. yesterday he reportedly had several episodes of vomiting but this improved somewhat by this morning. when his son came home ~3:30pm he found the pt on the floor, staring into space and minimally responsive. he brought him to where he was tachycardic and hypotensive to 70/60. he was given vanco/levo/flagyl/gent and decadron for presumed sepsis and was intubated, presumably for airway protection and for sedation for scanning (according to his daughter). head ct was negative. abd ct showed a distended colon with fluid and fecal material, no bowel wall thickening or edema and no pneumatosis; mild pericolic fat induration in the left lateral mid abdomen and proximal to mid descending colon; and fecal impaction in the rectum. he received 6l ivf resuscitation and peripheral dopamine was started for hypotension to the 70s. he was then medflighted to for further management. . in the ed, a rij central line was placed. he received further fluid resuscitation and was disimpacted. peripheral dopamine was continued and he was transferred to the intubated and sedated. on arrival, an axillary arterial line was placed in the right arm and dopamine was changed to levophed and vasopressin was added. past medical history: htn ibs hernia repair hip fx hypercholesterolemia mi s/p stent at social history: lives with son family history: unknown physical exam: vs: 97.0, 122, 86/57, 14, 96% 100% fio2 vent: ac, peep 5, fio2 1.0, tv 550, rr 14 gen: intubated, sedated, not responsive to commands heent: pupils equal, round, sluggishly reactive to light, eomi lungs: ctab cv: tachycardic, rr, nl s1s2 abd: hypoactive bowel sounds, markedly distended, soft, tympanitic ext: cool, mottled, no clubbing pertinent results: 10:30pm glucose-196* lactate-3.9* k+-4.2 10:22pm glucose-233* urea n-46* creat-1.6* sodium-144 potassium-4.3 chloride-116* total co2-15* anion gap-17 10:22pm estgfr-using this 10:22pm ck(cpk)-165 10:22pm ctropnt-0.08* 10:22pm ck-mb-9 10:22pm wbc-3.6* rbc-5.03 hgb-15.1 hct-43.4 mcv-86 mch-30.1 mchc-34.8 rdw-14.5 10:22pm neuts-36* bands-18* lymphs-28 monos-7 eos-0 basos-1 atyps-10* metas-0 myelos-0 10:22pm plt count-129* 10:22pm pt-16.5* ptt-38.7* inr(pt)-1.5* 10:22pm fibrinoge-422* d-dimer-1450* 10:22pm urine color-yellow appear-clear sp -1.013 10:22pm urine blood-lg nitrite-neg protein-tr glucose-neg ketone-tr bilirubin-sm urobilngn-1 ph-6.5 leuk-neg 10:22pm urine rbc->50 wbc-21-50* bacteria-few yeast-none epi-1 10:22pm urine granular-0-2 . ct abdomen/pelvis impression: 1. dilated loops of large bowel with air-fluid levels suggestive of or large bowel obstruction. small amount of intraperitoneal fluid in the pelvis. 2. small bilateral pleural effusions and associated atelectasis. 3. 1.2 cm hypodensity in the spleen, which is not characterized well on this non-contrast study, but likely a hemangioma. 4. cholelithiasis, without ct evidence of cholecystitis. brief hospital course: this in an 81 yo m with a pmh of cad, transferred from osh for sepsis. the source of sepsis was unclear. however, bowel etiology was likely given the abdominal distension on physical exam. other possible etiology considered were pna or urosepsis. he was started on broad coverage antibiotics, vasopressors and fluids were continued. the patient was evaluated by surgery for possible intervention, however the decision was made not to go to the or immediately as there was no clear indication and the pt. performance status was poor and was high risk for surgery. the patient also needed respiritory support with a ventilator. after discussion with his daughter (hcp) and other family members the decision was made to focus on comfort measures. vasopressors, fluids, antibiotics were stopped, ventilator support was withdrawn in accordance with the wishes of the family. the patient expired peacefully. the family agreed to a autopsy to further investigate the cause of death. medications on admission: asa crestor lisinopril discharge medications: expired discharge disposition: expired discharge diagnosis: expired discharge condition: expired discharge instructions: expired followup instructions: expired procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours insertion of endotracheal tube infusion of vasopressor agent diagnoses: acute kidney failure, unspecified unspecified septicemia other and unspecified hyperlipidemia acute respiratory failure septic shock systemic inflammatory response syndrome due to noninfectious process with acute organ dysfunction irritable bowel syndrome other impaction of intestine 

Answer: The patient is high likely exposed to
