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: sulfa (sulfonamide antibiotics) attending: chief complaint: 1. severe constant epigastric abdominal pain 2. jaundice major surgical or invasive procedure: : ptbd placement history of present illness: 71-y.o. male recently admitted -- for abdominal pain and jaundice, underwent with sphincterotomy on c/b perforation with retroperitoneal free air. a biliary stent was placed over the perforation and the patient was discharged home in stable condition. he returns with gradual onset severe constant epigastric abdominal pain and jaundice since . he was able to eat but has since had no appetite. +flatus. past medical history: -prostate cancer-dx tx with external radiation-reports last psa was "0". -dm2 - renal mass . psh: appendectomy surgical removal of scarring in the penis after xrt social history: pt is a retired pipefitter. he denies smoking cigarettes, but reports smoking cigars years ago, reports drinking 2 beers daily, denies h.o drug use. family history: mother-lung cancer father with type 2 dm physical exam: on discharge: vss, afebrile gen: awake, alert, nad, slightly jaundiced heent: ncat, eomi, perrla, icteric. resp: ctab, no respiratory distress. cardio: rrr gi: soft, nt/nd, right flank with ptbd drain to gravity. extremities: wwp, no cce. pertinent results: 06:07pm blood wbc-11.9*# rbc-4.81 hgb-15.1 hct-42.6 mcv-89 mch-31.3 mchc-35.3* rdw-13.7 plt ct-279# 06:07pm blood glucose-177* urean-11 creat-0.8 na-130* k-4.4 cl-93* hco3-25 angap-16 06:07pm blood alt-340* ast-236* totbili-7.7* 06:07pm blood totprot-6.8 albumin-4.1 globuln-2.7 calcium-9.3 phos-2.0* mg-1.8 02:11am blood wbc-6.3 rbc-3.81* hgb-11.5* hct-33.2* mcv-87 mch-30.1 mchc-34.6 rdw-14.5 plt ct-155 02:11am blood glucose-116* urean-15 creat-0.7 na-139 k-4.1 cl-109* hco3-23 angap-11 07:15am blood alt-202* ast-89* ld(ldh)-184 alkphos-205* totbili-3.5* 02:11am blood calcium-8.1* phos-2.0* mg-2.4 9:25 pm blood culture blood culture, routine (preliminary): enterobacter aerogenes. final sensitivities. this organism may develop resistance to third generation cephalosporins during prolonged therapy. therefore, isolates that are initially susceptible may become resistant within three to four days after initiation of therapy. for serious infections, repeat culture and sensitivity testing may therefore be warranted if third generation cephalosporins were used. sensitivities: mic expressed in mcg/ml _________________________________________________________ enterobacter aerogenes | cefepime-------------- <=1 s ceftazidime----------- <=1 s ceftriaxone----------- <=1 s ciprofloxacin---------<=0.25 s gentamicin------------ <=1 s meropenem-------------<=0.25 s piperacillin/tazo----- <=4 s tobramycin------------ <=1 s trimethoprim/sulfa---- <=1 s anaerobic bottle gram stain (final ): reported by phone to neelish @ 1430, . gram negative rod(s). 5:22 am mrsa screen source: nasal swab. **final report ** mrsa screen (final ): no mrsa isolated. time taken not noted log-in date/time: 3:38 am urine site: not specified **final report ** urine culture (final ): no growth. liver or gallbladder us: impression: 1. biliary stent not visualized on the current ultrasound exam. consider kub to assess the position. 2. cholelithiasis with trace pericholecystic fluid. negative son sign. no specific sign for acute cholecystitis. 3. mild intrahepatic biliary ductal dilatation, slightly more prominent from prior. 4. unchanged left hepatic cyst. perc transhepatic biliary drainage: cholangiogram findings: 1. moderately dilated intrahepatic bile ducts and dilated common bile duct up to the lower end. 2. a filling defect is seen at the lower end of cbd suggestive of calculus. 3. no flow of contrast is seen from the cbd into the duodenum. 4. the guidewire or catheter could not be passed beyond the cbd obstruction into the duodenum and an external drain was placed. impression: successful placement of a 6 french external biliary drain with the pigtail formed within the cbd. the catheter is attached to a bag for external drainage. cholangiogram revealed dilated intra- and extra-hepatic bile ducts with filling defect at the lower cbd, presumably a stone brief hospital course: the patient with cbd strictures s/p sphincterotomy c/b bile duct perforation on was admitted to the general surgical service with increased abdominal pain and fever. on date of admission, the patient underwent abdominal ultrasound, during which biliary stent was not visualized. patient's blood and urine cultures were sent, he was started on iv unasyn, and admitted in icu. in icu patient was resuscitated with iv fluids and on hd # 2 patient was transferred on the floor. the patient was hemodynamically stable. on hd # 2, patient underwent cholangiogram and placement of # 6 french ptb drain. after drain placement, patient's lft started to improve, patient's diet was advanced to regular. patient was evaluated by dr. and he was scheduled for elective whipple procedure on . on hd # 3, patient's pain was well controlled, he tolerated regular diet, he voided without problem, and ambulated without assist. blood cultures came back positive for gnr and iv unasyn was changed to po ciprofloxacin. patient was discharged home same day with services for ptbd management in stable condition. . at the time of discharge, the patient was doing well, afebrile with stable vital signs. the patient was tolerating a regular diet, ambulating, voiding without assistance, and pain was well controlled. the patient received discharge teaching and follow-up instructions with understanding verbalized and agreement with the discharge plan. medications on admission: lipitor 20 mg daily amlodipine 5 mg daily omeprazole 20 mg discharge medications: 1. omeprazole 40 mg capsule, delayed release(e.c.) sig: one (1) capsule, delayed release(e.c.) po daily (daily). 2. ciprofloxacin 500 mg tablet sig: one (1) tablet po twice a day for 10 days. disp:*20 tablet(s)* refills:*0* 3. lipitor 20 mg tablet sig: one (1) tablet po once a day. 4. norvasc 5 mg tablet sig: one (1) tablet po once a day. 5. colace 100 mg capsule sig: one (1) capsule po once a day. 6. hydrocodone-acetaminophen 5-500 mg tablet sig: one (1) tablet po q6h (every 6 hours) as needed for pain. disp:*20 tablet(s)* refills:*0* discharge disposition: home with service facility: home health care discharge diagnosis: 1. bile duct perforation s/p 2. cbd strictures 3. right renal mass 4. bacteremia discharge condition: mental status: clear and coherent. level of consciousness: alert and interactive. activity status: ambulatory - independent. discharge instructions: please resume all regular home medications , unless specifically advised not to take a particular medication. also, please take any new medications as prescribed. please get plenty of rest, continue to ambulate several times per day, and drink adequate amounts of fluids. avoid lifting weights greater than lbs until you follow-up with your surgeon, who will instruct you further regarding activity restrictions. avoid driving or operating heavy machinery while taking pain medications. please follow-up with your surgeon and primary care provider (pcp) as advised. ptbd care: *please look at the site every day for signs of infection (increased redness or pain, swelling, odor, yellow or bloody discharge, warm to touch, fever). *if the drain is connected to a collection container, please note color, consistency, and amount of fluid in the drain. call the doctor, nurse practitioner, or vna nurse if the amount increases significantly or changes in character. be sure to empty the drain frequently. record the output, if instructed to do so. *wash the area gently with warm, soapy water or 1/2 strength hydrogen peroxide followed by saline rinse, pat dry, and place a drain sponge. change daily and as needed. *keep the insertion site clean and dry otherwise. *avoid swimming, baths, hot tubs; do not submerge yourself in water. *make sure to keep the drain attached securely to your body to prevent pulling or dislocation. followup instructions: you scheduled for elective whipple procedure on . please call dr. office at if you have any questions. procedure: other percutaneous procedures on biliary tract diagnoses: diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled personal history of malignant neoplasm of prostate bacteremia mechanical complication due to other implant and internal device, not elsewhere classified obstruction of bile duct 

Answer: The patient is high likely exposed to
