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: iv contrast: nonionic iv optiray contrast was used for the patient's history of allergies. ct of the abdomen with contrast: there is a moderate sized left and a small right pleural effusion. associated dependent atelectasis is seen bilaterally. a small amount of fluid is seen within the left major fissure. the base of the heart is unremarkable. left hepatic pneumobilia is seen, as was noted on previous exam. the patient is status post cholecystectomy. the liver, pancreas, adrenal glands, stomach, kidneys, and bowel loops are normal in appearance. the kidneys enhance and excrete contrast promptly and symmetrically. note is made of bilateral fetal lobulation of both kidneys. an ivc filter is noted just below the level of the renal veins, and the inferior legs of the filter are noted to be outside the ivc, as was noted on previous exam of . there is no free fluid or free air. the appendix is identified within the deep mid-pelvis from a low-lying cecum, and is normal in appearance. ct of the pelvis with contrast: the bladder and distal ureters are normal. no free fluid or masses. the uterus and adnexa are unremarkable. there are a few sigmoid diverticula without evidence of diverticulitis. bone windows show no suspicious lesions. coronal and sagittal reconstructions: images reconstructed in the sagittal and coronal planes show no bowel pathology. a normal appendix is identified (over) 6:44 pm ct abdomen w/contrast; ct pelvis w/contrast clip # ct reconstruction; ct 150cc nonionic contrast reason: eval for obstruction/hernia/intraabdominal infection contrast: optiray amt: 150 ______________________________________________________________________________ final report (cont) on the coronal view. impression: 1. no ct evidence for appendicitis. 2. bilateral pleural effusions, moderate on the left and small on the right. associated bilateral dependent atelectasis is also appreciated. 3. no evidence for bowel pathology or obstruction. procedure: venous catheterization, not elsewhere classified continuous invasive mechanical ventilation for 96 consecutive hours or more single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery diagnostic ultrasound of heart insertion of endotracheal tube insertion of temporary transvenous pacemaker system arterial catheterization open and other replacement of aortic valve with tissue graft implant of pulsation balloon open and other replacement of mitral valve with tissue graft extraction of other tooth cardiopulmonary resuscitation, not otherwise specified diagnoses: pneumonia, organism unspecified anemia, unspecified coronary atherosclerosis of native coronary artery congestive heart failure, unspecified acute kidney failure, unspecified unspecified acquired hypothyroidism atrial fibrillation methicillin susceptible staphylococcus aureus septicemia sepsis paroxysmal ventricular tachycardia personal history of other lymphatic and hematopoietic neoplasms acute respiratory failure cardiogenic shock septic shock other constipation acute and subacute bacterial endocarditis surgical operation with implant of artificial internal device causing abnormal patient reaction, or later complication,without mention of misadventure at time of operation streptococcus infection in conditions classified elsewhere and of unspecified site, other streptococcus streptococcal septicemia tachycardia, unspecified other and unspecified alcohol dependence, continuous infection and inflammatory reaction due to cardiac device, implant, and graft personal history of hodgkin's disease periapical abscess without sinus 

Answer: The patient is high likely exposed to
