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: technique: contiguous axial images were obtained from the thoracic inlet to the femoral heads after administration of 150 cc of optiray. nonionic contrast was used secondary to patient allergies. ct chest with contrast: there has been significant interval improvement in the appearance of the mediastinal collections after debridement. the collection measures approximately 2.3 x 3.7 cm compared with 3.4 x 4.1 cm on the prior study. there remain a few small pockets of fluid behind the manubrium. the drainage tube has been removed in the interval. multiple sternal wires are again identified secondary to the recent cabg procedure. the endotracheal tube has been removed in the interval. an ng tube is seen in the esophagus. there is dependent atelectasis at both lung bases. the bilateral pleural effusions have resolved. no significant axillary, mediastinal or hilar lymphadenopathy is identified. emphysematous changes are noted in both lung apices. ct abdomen with contrast: a simple cyst is again noted in the left lobe of the liver and measures 2.7 x 3.1 cm. no other abnormalities are identified in the liver. the gallbladder is not visualized. the pancreas, spleen, and adrenals are unremarkable. multiple simple cysts are identified in both kidneys. the ng tube is in appropriate position and terminates in the second portion of the duodenum. the proximal small bowel loops appear somewhat prominent and dilated compared with the more distal loops. surgical clips are identified in close proximety to the jejunum. an early mechanical small bowel obstruction cannot be excluded and followup is recommended. the colon is collapsed. there are multiple diverticuli of the sigmoid colon without evidence for (over) 12:01 am ct pelvis w/contrast; ct abdomen w/contrast clip # ct chest w/contrast; ct 150cc nonionic contrast reason: 67 yo male s/p cabg with mediastinitis s/p i & d. also with contrast: optiray amt: 150 ______________________________________________________________________________ final report (cont) diverticulitis. vascular calcifications are noted in the aorta. ct pelvis with contrast: the distal ureters and bladder are unremarkable. no free fluid or pelvic lymphadenopathy is identified. bone windows demonstrate no suspicious sclerotic or lytic lesions. impression: 1. interval improvement in the appearance of the sternal collection s/p debridement. small residual areas are noted behind the manubrium. 2. dependent bibasilar atelectasis. 3. emphysematous changes at the apcies. 4. hepatic cysts which are unchanged. 5. diverticulosis without evidence for diverticulitis. 6. prominent appearing proximal small bowel loops when compared with the more distal loops, an early mechanical small bowel obstruction cannot be excluded. followup is recommended. procedure: venous catheterization, not elsewhere classified continuous invasive mechanical ventilation for 96 consecutive hours or more parenteral infusion of concentrated nutritional substances other endoscopy of small intestine diagnostic ultrasound of heart enteral infusion of concentrated nutritional substances incision of mediastinum other incision of pleura pulmonary artery wedge monitoring diagnoses: other postoperative infection unspecified pleural effusion chronic airway obstruction, not elsewhere classified other shock without mention of trauma bacteremia paralytic ileus other vascular complications of medical care, not elsewhere classified mediastinitis phlebitis and thrombophlebitis of deep veins of upper extremities 

Answer: The patient is high likely exposed to
