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: patient recorded as having no known allergies to drugs attending: chief complaint: anemia with acute gi blood loss major surgical or invasive procedure: : gastrectomy and gastrojejunostomy history of present illness: 44 yo gentleman known cholangiocarcinoma s/p l hepatectomy in by dr.. microscopic positive margins. received chemo radiation followed by chemo gemcitobine and oxaliplatin. on his 2nd cycle. last dose on mon . presented to outside ed with one week history of feeling weak and dizzy. retrospectively says he had been passing dark coloured stools. fainted in the ed apparently hypotensive recovered with fluids. lowest bp 100 systolic lowest hct 11.7. transfused 6 units prbc. hct prior to transfer was 27. egd outside bulbar duodenum nodular mass possibly neoplasm with ooze. not biopsied epinephrine injected, inspite of which there was a slow ooze. ct abd done outside reported as normal past medical history: l1 ruptured disc repair in . has had several colonoscopies given mothers h/o colon ca. last colonoscopy 3 yrs ago s/p polyp removal. social history: quit smoking 6 months ago. prior to that he has smoked 1ppd on & off since age 17. etoh - none since 3 weeks ago. h/o heavy drinking on & off with attendance at aa in the past. smoked marijuana as teenager, but denies now and no h/o ivda. married with 4 children ages . employed at sears. family history: father died at age 80, dm. mother a&w with h/o colon ca s/p resection. physical exam: vitals:98.4f, hr 92/min, rr16 sat96% gen: a&o, heent: pale cv: rrr, no murmurs lungs: clear bilat abd: nt/nd, soft, no masses no tenderness rectal: no masses guaiac positive ext: no edema pertinent results: at admission: hct-26.0*# wbc-13.8*# rbc-3.85* hgb-12.1* hct-33.8* mcv-88 mch-31.4 mchc-35.9* rdw-18.4* plt ct-117*# pt-12.9 ptt-26.2 inr(pt)-1.1 glucose-127* urean-18 creat-0.7 na-141 k-3.9 cl-110* hco3-25 angap-10 alt-44* ast-50* alkphos-123* amylase-28 totbili-0.5 albumin-2.9* calcium-7.5* phos-3.6 mg-1.9 at discharge: wbc-4.8 rbc-2.82* hgb-8.6* hct-26.1* mcv-93 mch-30.4 mchc-32.7 rdw-14.6 plt ct-316 glucose-96 urean-15 creat-0.7 na-139 k-3.9 cl-104 hco3-26 angap-13 alt-99* ast-55* alkphos-568* totbili-0.9 brief hospital course: 44yo m s/p l hepatectomy for cholangioca , tx from osh w/ ugi bleed (hct 11 @ osh), egd there w/ ? duodenal mass. given 6u prbc at osh; nasogastric tube was in place, serial hct was followed and he was on iv pantoprazole. he underwent egd on which showed extensive clot and fresh blood oozing in the duodenal bulb. he was given 3 units prbcs and hct slowly drifted down over the next 2 days. he was kept npo and received tpn. h pylori obtained at admission was negative. blood cultures were drawn on hd 3 in response to temp of 101.2, these were negative. ct of the abdomen was concerning for duodenal ulcer as well as diffuse thickening of the stomach. on he underwent angiogram which showed celiac and sma arteriogram demonstrated a vascular stump off the common hepatic artery believed to be the stump of the left hepatic artery, a replaced right hepatic artery supplied from the sma, and gda coming off of the common hepatic artery. there is no active extravasation or evidence of active bleeding. no embolization was performed. he was continuing to have transfusion requirements to maintain his hct and received an additional 25 units over the course of the week with 6 units the day that it was decided to take him to the or for an exploratory lap with dr for gastrectomy and gastrojejunostomy . no evidence of malignancy could be found at the time of exploration. there was concern that this was an infiltrating cholangiocarcinoma, however frozen sections did not show evidence of malignancy and final pathology on the gastrectomy portion submitted showed: - extensive hemorrhagic necrosis with associated transmural ulceration of the distal antrum/pylorus; focal microperforation is identified - fundic and uninvolved antral mucosa with minimal chronic, inactive inflammation, focal hemorrhage and epithelial regeneration. - no carcinoma seen. on (hd 13/pod3) he developed ards (a-a gradient 198, < 200), possibly secondary to transfusion reaction or possibly pneumonia. pt was continued on zosyn empirically and diuresed for concern of ards. he was placed on lateral ventilation with turning. again on he spiked temperature 101.8, repeat 101.5 and was pan cultured. all urine, blood and sputum (from bal) were no growth. he was still having low grade fevers through pod 9 and then on pod day 10 he again had fever to 101.1. he had been treated with iv vanco x 7 days, zosyn x 16 days and fluconazole 8 days from the time of admission. he was re cultured with the new fever and blood cultures are as yet negative but not finalized at the time of discharge. he was restarted on vanco and zosyn and then started on po augmentin for a 14 day total course to be completed at home. on he was extubated, remained on lasix drip, getting albumin. his hematocrit was much more stable following the surgery with a requirement of 5 more units and then stable from pod 5 until discharge. on he underwent a barium study to determine the patency of the anastomosis. this showed free flow of contrast from the stomach to the jejunum, no evidence for leak or obstruction. he continued to receive tpn for nutritional support. he was slowly restarted on diet once the anastomosis was judged to be patent, and is encouraged to use supplements. teaching was provided for small frequent meals and the use of the supplements at home as well. a culture was obtained from the jp drain (peritoneal fluid) on which grew staph aureus. from until discharge he remained completely afebrile, augmentin will be used upon discharge. additionally, due to a slight increase in the lfts, an ultrasound was performed showing patent vasculature and no biliary dilitation. the lfts started to trend down again prior to discharge. patient is ambulating, pain well managed, staples and drain are removed and he is tolerating po diet. lasix and metoprolol were d/c'd prior to discharge. medications on admission: none discharge medications: 1. pantoprazole 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q12h (every 12 hours). disp:*60 tablet, delayed release (e.c.)(s)* refills:*2* 2. oxycodone-acetaminophen 5-325 mg tablet sig: 1-2 tablets po q4h (every 4 hours) as needed for pain. disp:*30 tablet(s)* refills:*0* 3. amoxicillin-pot clavulanate 500-125 mg tablet sig: one (1) tablet po q8h (every 8 hours) for 10 days. disp:*30 tablet(s)* refills:*0* 4. colace 100 mg capsule sig: one (1) capsule po twice a day: take as long as using narcotic pain medication and as needed. disp:*60 capsule(s)* refills:*2* discharge disposition: home discharge diagnosis: upper gi bleed now s/p gastrectomy and gastrojejunostomy pmh: cholangiocarcinoma discharge condition: good/stable discharge instructions: please call dr office at for fever > 101, chills, nausea, vomiting, diarrhea, increased abdominal pain, inability to take food, fluids or medications. finish oral antibiotics as prescribed report dark stool drink enough fluids to keep urine light yellow in color take a supplement several times a day (ensure, carnation instant breakfast) in addition to your regular diet monitor incision for redness, drainage or bleeding you may shower, pat incision dry, leave open to air no driving if taking narcotic pain medication followup instructions: , md phone: date/time: 3:00 procedure: venous catheterization, not elsewhere classified venous catheterization, not elsewhere classified continuous invasive mechanical ventilation for 96 consecutive hours or more parenteral infusion of concentrated nutritional substances insertion of endotracheal tube arteriography of femoral and other lower extremity arteries endoscopic control of gastric or duodenal bleeding esophagogastroduodenoscopy [egd] with closed biopsy arteriography of other intra-abdominal arteries partial gastrectomy with anastomosis to jejunum transfusion of packed cells diagnoses: other iatrogenic hypotension unspecified pleural effusion acute posthemorrhagic anemia personal history of tobacco use alkalosis chronic or unspecified duodenal ulcer with hemorrhage, without mention of obstruction unspecified procedure as the cause of abnormal reaction of patient, or of later complication, without mention of misadventure at time of procedure phlebitis and thrombophlebitis of upper extremities, unspecified malignant neoplasm of intrahepatic bile ducts chronic or unspecified gastric ulcer with hemorrhage and perforation, without mention of obstruction 

Answer: The patient is high likely exposed to
