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 a 61 year old woman with past medical history of b cell lymphoma, recent rituxan treatment, crohn's disease, hepatitis c, who was admitted with a four to five day history of hacking cough, increased shortness of breath over the last five days. she reports cough over a month. a z-pak around . chest x-ray showed right upper lobe nodularity which was stable. symptoms improved but returned about four to five days ago. the patient denies fever, chills, rigors at home, cough was intermittent. the patient states it is difficult to bring up sputum. she has had poor p.o. intake over the last day. no recent flu shot. in the emergency department, the patient had a chest x-ray consistent with multifocal pneumonia and given one dose of levofloxacin. she has a new bandemia and white blood cell count. past medical history: 1. lymphoma, b cell, status post chop, rituxan in . 2. crohn's disease, status post total colectomy thirty-five years ago with an ileostomy. 3. hepatitis c cirrhosis. 4. anemia secondary to chronic blood loss. 5. history of pelvic abscess with drainage in . 6. squamous cell carcinoma of the nose. 7. depression. 8. vaginal bleeding. 9. hypertension. allergies: ampicillin - rash. social history: no alcohol or tobacco or intravenous drug use. health care proxy . lives in facility. family history: noncontributory. physical examination: the patient was afebrile on admission, blood pressure 116/74, 80% in room air, 94% on nonrebreather. no jugular venous distention. the oropharynx is clear. chest - egophony left lower lobe, right upper lobe rhonchi throughout. the heart is regular rate and rhythm, no murmurs, rubs or gallops. the abdomen is benign. extremities showed no edema. neurologic examination is nonfocal. laboratory data: on admission, left shift with 82 polys, 8 bands, 4 lymphocytes, white blood cell count 27.0, creatinine 0.8, blood urea nitrogen 25, hematocrit 46.1. chest x-ray showed multifocal pneumonia. electrocardiogram normal sinus rhythm at 75 beats per minute, normal axis and intervals, no st changes. no t wave inversions. hospital course: 1. hypoxia - the patient was admitted to medicine, however, her hypoxemia continued to progress. she had increased dyspnea and large a/a gradient. she was started on antibiotics which include ceftriaxone, azithromycin to cover pneumonia. she was added bactrim. cta to evaluate for pulmonary embolus was negative. the patient was transferred to the intensive care unit for respiratory distress, also attributed to her pneumonia. she was intubated for airway protection and increased work of breathing, likely due to infection. she was adult respiratory distress syndrome as well as possible lymphoma rituxan toxicity. her inr was 2.5 so pulmonary embolus was thought to be less likely. she was continued on her antibiotics of ceftriaxone and azithromycin. she was sent for bronchoscopy to check cytology as well. the patient was growing out gram positive cocci in the blood cultures. her antibiotics were changed to vancomycin and levofloxacin. she was started on pressors for hypotension, neo-synephrine and levofloxacin and was bronchoscoped. she remained hypotensive. her white blood cell count continued to increase to 36.0. her creatinine increased to 1.7. her legionella fungal cultures were negative. sputum culture was 2+ gram positive cocci in clusters. she became septic. source was considered to be her pneumonia. she was continued on her antibiotics. she was also added on gentamicin. the patient expired on , and time of death is 1830 despite maximum therapy. 2. hematology - the patient was in dic, elevated inr, liver failure. she had cirrhosis and her acute renal failure decreased urine output, likely the sepsis despite maximum therapy. final diagnoses: 1. sepsis. 2. multilobar pneumonia. 3. b cell lymphoma. 4. liver failure. 5. acute renal failure. 6. staphylococcus pneumoniae bacteremia. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified insertion of endotracheal tube enteral infusion of concentrated nutritional substances closed [endoscopic] biopsy of bronchus diagnoses: cirrhosis of liver without mention of alcohol acute kidney failure, unspecified acquired coagulation factor deficiency severe sepsis other malignant lymphomas, unspecified site, extranodal and solid organ sites defibrination syndrome other specified septicemias pneumonia due to streptococcus, unspecified 

Answer: The patient is high likely exposed to
