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, oxacillin, sulfa shift events: shift change patient on crrt, sbp dropping throughout night from ~mn-7:00am, sbp 120-130's, down to 90'-100's. cvvh machine/filter clotted off at ~8:45am, team notified/renal notified decision not restart at this time d/t patients total fluid removal (wt ~60kg on , currently 54kg, as well as overall net loss), as well as "normalizing" cr/and electrolytes (baseline cr~2). blood pressure down to ~84 this am s/p cvvh, total of 1l of fluid given (250ns fluid bolus) with only temporary effect/results. started on levophed at ~12:00, titrated up all afternoon, now on levophed 0.15/mcg/kg/min, goal map's>60. *started on argatroban for pmh clot in ivc, started at 0.5mcg/kg/min 16:00 ptt pndg, goal 60-80. *access is an issue. patient has piv x2 wnl, however med's infusing in all iv's (non-compatible), iv nurse in to assess patient at this time. ros: neuro: sedated on fentanyl 20mcg/hr and versed 2mg/hr, sedation decreased this am, d/t hypotension. no s/sx's of discomfort. grimaces when suctioned, bites down on oral suction, however does not follow commands. impaired gag and cough, perl 2mm, brisk. cv: hr 70's, nsr, no ectopy. continues on amiodarone 400mg/po (off gtt since 6am.) bp see above, a-line slightly dampened. pulses 3+. trace edema in extremities. tmax 99.8 rectal. resp: a/c 400x18(at times +10)/8/40%, o2 sat's 98%, dropped to 91% x1 s/p suctioning for moderate tan secretions, o2 sat's 98%, abg s/p sxn, wnl. ls at 16:00 clear anterior upper, crackles lower. sputum sent.

Answer: The patient is high likely exposed to
