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 had down's syndrome, hypothyroidism, peripheral vascular disease and adrenal insufficiency. he came into the hospital to have a peg placed as well as a pacemaker. physical examination: vital signs on admission included a temperature of 97.1??????f, a pulse of 102, a blood pressure of 98/58, respirations of 20 and an oxygen saturation of 100% on room air. the patient was alert but not conversant, appearing older than his age. the pupils were equal and reactive to light. the extraocular muscles were intact. there was no jugular venous distention. the lungs were clear to auscultation bilaterally with no wheezes, rales or rhonchi. the heart had a regular rate and rhythm with an s1 and s2 and no murmurs, rubs or gallops. the abdomen had positive bowel sounds and was soft, nontender and nondistended. the extremities had no cyanosis or edema. on neurological examination, there was 5/5 strength. sensation was intact. this was a nonfocal examination. past medical history: the patient was recently discharged from the hospital for treatment of aspiration pneumonia, during which time he went to the unit and experienced sinus arrest. he was discharged and treated for methicillin resistant staphylococcus aureus pneumonia prior to returning on for peg placement and pacemaker placement. hospital course: the peg was placed without any problems on and then the patient was noticed to have a cellulitis around the picc site, so the picc was pulled and sent for cultures. the tip and the wound as well as blood cultures did not grow anything; they were negative. the patient never experienced an increased white blood cell count and was afebrile for the entire stay. it was ultimately decided that this was a local irritation of the picc site. therefore, pacemaker placement was put off by a day. the patient had his pacemaker placed on . he had some problems with secretions during the procedure and was sent to the unit for overnight observation. he came back to the floor on for decreased urine output and decreased oxygen saturation. the patient was treated with five days of vancomycin, which was discontinued due to the fact that the picc site was noted to have local irritation, not cellulitis. condition/disposition: at this time, he is doing better with increased urine output. his oxygen saturation is 94% on room air. he is now able to return to nursing home. discharge diagnoses: status post peg placement. status post pacemaker placement. down's syndrome. hypothyroidism. status post aspiration pneumonia. adrenal insufficiency. , m.d. dictated by: medquist36 procedure: enteral infusion of concentrated nutritional substances percutaneous [endoscopic] gastrostomy [peg] initial insertion of single-chamber device, rate responsive initial insertion of transvenous lead [electrode] into ventricle diagnoses: adrenal cortical steroids causing adverse effects in therapeutic use retention of urine, unspecified dementia in conditions classified elsewhere without behavioral disturbance sinoatrial node dysfunction urinary complications, not elsewhere classified down's syndrome 

Answer: The patient is high likely exposed to
