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 83-year-old male with a history of progressive body dementia and a seizure disorder who was a resident of with a recent general functional decline (since two months) that has manifested as a decrease interactiveness, recent anorexia (refused orals), and decrease functional ability (activities of daily living). he was noted by his neurologist to be likely progressing with his dementia, as recently as . he was started on sinemet at that time. hospital course: he presented to with fevers of 102 degrees fahrenheit, a heart rate of 112, and a blood pressure that was 90/palp, and a respiratory rate of 36, and saturating 100% on 15 liters with decreased urine output. he was also noted to be unresponsive on admission. a chest x-ray was consistent with a right middle lobe infiltrate. he was given levofloxacin, and vancomycin, as well as flagyl for presumed pneumonia versus urinary tract sepsis. he was hypotensive with a poor response to fluid boluses (he was given a total of 8 liters in the emergency department). he was started on a dopamine drip with no response. he was switched to neo-synephrine with an increased blood pressure and arousability. he was transferred to the medical intensive care unit where his hypotension worsened, requiring a second pressor (vasopressin), plus fluid boluses. he became increasingly acidotic with lactate initially at 8 that increased to 20.7 during the evening of . he also had worsening bicarbonate levels from 25 initially, decreasing to 6. he was intubated with a pre-intubation arterial blood gas that was 7.04/22/122. post intubation, his arterial blood gas was 7.11/23/215 on 50% oxygen. he was given sodium bicarbonate followed by a sodium bicarbonate drip. his antibiotics were continued, and he was given stress-dose steroids for presumptive adrenal insufficiency in the setting of sepsis. levophed was added on as another pressor for hypotension. blood cultures from earlier that day in the emergency department grew gram-negative rods, and the patient was started on ceftazidime. he was also noted to have severe coagulopathy and was treated aggressively with fresh frozen plasma and vitamin k. he was also transfused several units of packed red blood cells for a rapidly decreasing hematocrit in the setting of fluid restriction. despite all of these aggressive interventions (including triple pressors), the patient's mean arterial pressure remained in the 40s, and his heart rate started to drop. at 5:45 p.m., on , he became asystolic on the monitor. his pupils became fixed and dilated, and he expired. his sister was present and refused the autopsy at that time. the attending, as well as the , were notified of his death. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified insertion of endotracheal tube arterial catheterization pulmonary artery wedge monitoring diagnoses: pneumonia, organism unspecified urinary tract infection, site not specified other convulsions acute respiratory failure defibrination syndrome other shock without mention of trauma other septicemia due to gram-negative organisms 

Answer: The patient is high likely exposed to
