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: service: history of present illness: status post aspiration pneumonia, status post intubation. the patient was admitted to the medical intensive care unit on . his hospital course during the intensive care , to current when he was on the floor. this is a 70 year old white male admitted from home on , for coffee ground emesis with decreased blood pressure, increasing heart rate and mild upper quadrant pain. the patient was intubated in the emergency department for hypoxia and airway protection. . during the hospital stay, the patient has had several medical issues, the first being respiratory failure for which he was intubated. during the postintubation, the patient's chest x-ray was clear. he was on oxygen by face mask, 50% with oxygen saturation in the mid to high 90% range. upon breathing room air, his oxygen saturation decreases to high 80s. he was largely noncompliant with keeping his oxygen on due to his dementia. second issue is aspiration pneumonia. the patient has been kept npo. nasogastric tube was considered to be placed but was unable to place given the patient was not able to swallow. the patient had a speech and swallow study done and aspirated several teaspoons of water. the patient then underwent a modified barium swallow and this showed that he also failed the study. because the patient is not a candidate for a feeding tube, he was started on a modified diet and will be carefully monitored post-discharge at this nursing home. episodes of hypotension - the patient has been shown to be responsive to boluses and has received several 250 cc normal saline boluses which has brought up his blood pressure. congestive heart failure - his hospital course did not demonstrate any problems associated with congestive heart failure. nutrition - again, the patient is npo because of strict aspiration precautions. he received d5w at 75 cc/hour of intravenous fluids and would not receive tube feeds. the family has refused a percutaneous endoscopic gastrostomy tube given that the patient has risk of pulling out the tube. he wil lbe given a modified diet, as above. gastrointestinal bleed - we continued to follow the hematocrit during hospital course and it demonstrated no significant drop in hematocrit. most recent hematocrit was high 28.0 for which he received one unit of packed red blood cells. he received protonix throughout the course and had a rectal tube placed. hematology wise, he had a hematocrit in the high 20s, low 30s, below 30 was transfused with one unit. renal - he has a history of chronic renal failure but his creatinine has been stable. neurologically, he has a history of being agitated as well as anxiety. he receives depakote and benzodiazepines throughout the hospital course. code status is dnr/dni. condition on discharge: on discharge, the patient is in stable condition and will return back to home. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for 96 consecutive hours or more other endoscopy of small intestine insertion of endotracheal tube enteral infusion of concentrated nutritional substances arterial catheterization diagnoses: pure hypercholesterolemia acute kidney failure, unspecified unspecified septicemia chronic airway obstruction, not elsewhere classified acute respiratory failure pneumonitis due to inhalation of food or vomitus hemorrhage of gastrointestinal tract, unspecified alcohol-induced persisting dementia 

Answer: The patient is high likely exposed to
