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: the patient is an 86 year old man with multiple co-morbidities who presented after being found unresponsive at the nursing home with a temperature of 100.3 f.; blood pressure of 150/70; oxygen saturation 79% to room air. the patient was found to be more lethargic and more congested on examination and the patient was then sent to the emergency room at and first admitted to the medical intensive care unit. hospital course: while in the intensive care unit, the patient received frequent suctioning, however, was not intubated during this initial part of the stay. the patient was made "do not resuscitate" and "do not intubate" after the status was confirmed with the health care proxy, who is the patient's niece. the chest x-ray performed right after admission also showed possible bilateral patchy opacities consistent with pneumonia. the patient was started on levofloxacin and flagyl. after the patient was stabilized and no longer required q. one hour suctioning, the patient was transferred to the medical floor, where the patient's course remained stable. the patient required throughout the hospitalization, frequent suctioning every two to three hours. this frequency later on subsided to every three to four hours. the patient's cultures grew back methicillin resistant staphylococcus aureus pneumonia and the patient was also started on vancomycin. during his hospitalization, the patient slowly became more responsive, however, he remained alert and oriented times one to his name only throughout his hospitalization. his oxygen saturation remained stable throughout the hospital stay at 94 to 96% on 50% of face mask. the patient also was initially admitted with a high sodium of 150; this subsequently decreased to a level of 140 to 143 after the first day of hospitalization. the patient's metformin was held and an insulin sliding scale was started for the patient and the patient's glucose levels remained stable throughout his hospital stay. in addition, the patient's blood pressure medications were held as well and his blood pressure readings remained stable throughout his hospital stay. condition on discharge: the patient's condition on discharge is stable. discharge status: his discharge status is stable. discharge diagnoses: 1. methicillin resistant staphylococcus aureus pneumonia. discharge medications: 1. vancomycin one gram q. 12 hours. 2. aspirin 81 mg q. day. 3. multivitamins. 4. acetaminophen 650 mg q. four to six hours p.r.n. 5. erythromycin 0.5% ophthalmologic ointment 0.5 three times a day. 6. levofloxacin 500 mg q. 24 hours intravenously. 7. metronidazole 500 mg q. eight hours intravenously. 8. docusate sodium 100 mg twice a day. 9. brimonidine tartrate 0.15% ophthalmologic solution, one drop q. eight hours. disposition: the patient is to be discharged to a nursing home. discharge instructions: 1. the patient is also to be discharged on tube feeds, which were started on day three of hospitalization at a rate of 40 to 60 cc per hour. 2. the patient is being discharged to a nursing home. dr., 12-aew dictated by: medquist36 procedure: venous catheterization, not elsewhere classified enteral infusion of concentrated nutritional substances non-invasive mechanical ventilation diagnoses: unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled unspecified protein-calorie malnutrition infection with microorganisms resistant to penicillins unspecified glaucoma other persistent mental disorders due to conditions classified elsewhere pneumonitis due to inhalation of food or vomitus hyperosmolality and/or hypernatremia 

Answer: The patient is high likely exposed to
