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: this is an 89-year-old male nursing home resident who has a complicated past medical history as listed. he was in his usual state of health until when he was noted to have a temperature of 102 axillary at hemodialysis. during hemodialysis, on , he had blood cultures drawn and was given vancomycin and gentamicin, and subsequently referred to the emergency department. no further history is available due to the language barrier. in the emergency department, he was given lopressor for a heart rate in the 170s (irregular). subsequently, his blood pressure dropped to 54/palp, so he was started on a dopamine drip. this was later changed to a neo-synephrine drip and the patient was transferred to the medical intensive care unit. past medical history: 1. right middle cerebral artery stroke with a residual left hemiparesis and left neglect. 2. end-stage renal disease secondary to nephrotic syndrome, on hemodialysis since . 3. atrial fibrillation times nine years (never anticoagulated). 4. hypertension. 5. dementia. 6. methicillin-resistant staphylococcus aureus colonization. 7. question history of clostridium difficile. 8. g-tube placed on . 9. history of hepatitis b. 10. history of aspiration pneumonia. 11. history of gastric polyps. 12. status post appendectomy. 13. status post hernia repair. 14. status post prostate surgery times two. 15. hydrocele times eight years. medications on admission: 1. tube feeds, nova, source renal, full strength 80 cc per hour from 11 p.m. to 3 p.m. 2. saliva substitute p.o. t.i.d. 3. ilotycin to both eyes q.h.s. 4. famotidine oral suspension 2.5 cc q.d. 5. dulcolax 10 mg p.r. every three days. 6. folic acid 1 mg p.o. q.d. 7. aspirin 325 mg p.o. q.d. 8. heparin 5000 units subcutaneous b.i.d. 9. lopressor 75 mg p.o. t.i.d. 10. imodium p.r.n. medications on transfer: 1. lopressor 50 mg p.o. b.i.d. 2. gentamicin 80 mg after dialysis. 3. vancomycin 1 g dosed by levels. 4. flagyl 500 mg p.o. b.i.d. 5. prevacid suspension 30 mg p.o. q.d. 6. aspirin 325 mg p.o. q.d. 7. heparin 5000 units subcutaneous p.o. b.i.d. 8. ceftriaxone 1 mg p.o. q.d. 9. albuterol and atrovent nebulizers. 10. tube feeds. social history: the patient is a resident of nursing home since . he is a widower. his son makes health care decisions for him. physical examination on presentation: on transfer, temperature was 97.9, blood pressure 115/45, pulse 109, respiratory rate 22, oxygen saturation 98% on room air. in general, russian-speaking, groaning, ill-appearing. head, ears, nose, eyes and throat revealed pupils were equal, round, and sluggish bilaterally. neck revealed left subclavian line in place (hickman). cardiovascular revealed irregularly irregular tachycardia. no murmurs. lungs revealed upper airway sounds bilaterally. abdomen was soft, nontender, and nondistended, positive bowel sounds. g-tube in place. extremities revealed trace pitting edema bilaterally. hospital course: in the medical intensive care unit, the right port-a-cath was removed due to purulent drainage being present. initial antibiotic coverage included vancomycin for a possible line infection, levofloxacin for the question of pneumonia, flagyl for his history of clostridium difficile, and gentamicin. when the patient's urine cultures showed escherichia coli resistant to gentamicin and quinolones, the levofloxacin and gentamicin was discontinued. the patient was started on ceftriaxone on . the patient's fevers defervesced, and he was gradually weaned off pressors by . the patient required a diltiazem drip for rate control until when he was transitioned to p.o. lopressor. the patient had a temporary hemodialysis catheter in place after the old line was removed. a hickman catheter was placed on , and the patient underwent hemodialysis on and . during the first day on the regular floor, there was some difficulty in controlling the patient's rapid atrial fibrillation. improved control was obtained with the addition of oral diltiazem in addition to his lopressor. on , flagyl was discontinued as there was no evidence that clostridium difficile was involved in his current infection. at this time, the plan is for ceftriaxone and vancomycin to be administered at hemodialysis for a total of two weeks of therapy. at the time of this dictation, all of the patient's blood cultures demonstrated no growth to date. his line swab from showed mixed flora including methicillin-resistant staphylococcus aureus. his sputum culture from showed oropharyngeal flora. his urine cultures from showed escherichia coli. discharge diagnoses: 1. sepsis, urinary tract infection versus line infection. 2. rapid atrial fibrillation. medications on discharge: 1. aspirin 325 mg per g-tube q.d. 2. heparin 5000 units subcutaneous b.i.d. 3. ceftriaxone at hemodialysis. 4. vancomycin at hemodialysis. 5. lopressor 75 mg p.o. t.i.d. 6. diltiazem 30 mg p.o. q.i.d. 7. ultracal with promod at 70 cc per hour continuous. condition at discharge: medically stable for discharge to rehabilitation with continued antibiotic treatment at hemodialysis. discharge status: to rehabilitation.
