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: axial images of the chest, abdomen and pelvis were obtained with 150 cc optiray. nonionic intravenous contrast was used secondary to patient's history of allergies. comparison: not available. ct chest with iv contrast: the heart and great vessels appear unremarkable. there is no pericardial or pleural effusion. there are several small pretracheal lymph nodes, none of which meets the ct criteria for pathologic enlargement. there is no significant hilar or axillary lymphadenopathy. there are no pulmonary masses or nodules. there are bilateral small focal consolidations at the lung bases posteriorly, with air bronchograms noted within. ct abdomen with iv contrast: the liver, gallbladder, pancreas, spleen, adrenals, and kidneys appear unremarkable. the visualized small and large bowel loops are within normal limits. there is no significant mesenteric or retroperitoneal lymphadenopathy. there is no free air or free fluid within the abdomen. ct pelvis with iv contrast: the distal uretes, urinary bladder and rectum appear unremarkable. there is a foley catheter noted within the urinary bladder. there is no pelvic lymphadenopathy or pelvic free fluid. bone windows demonstrate no evidence of suspicious or sclerotic lesions. impression: 1. there are bilateral consolidations at the lung bases posteriorly, and infectious etiology should be considered in the proper clinical setting. 2. no evidence of intra-abdominal abscess formation. procedure: venous catheterization, not elsewhere classified continuous invasive mechanical ventilation for 96 consecutive hours or more parenteral infusion of concentrated nutritional substances diagnostic ultrasound of heart insertion of endotracheal tube enteral infusion of concentrated nutritional substances other electric countershock of heart arterial catheterization pulmonary artery wedge monitoring cardiopulmonary resuscitation, not otherwise specified diagnoses: congestive heart failure, unspecified acquired coagulation factor deficiency other pulmonary insufficiency, not elsewhere classified aortic valve disorders paroxysmal ventricular tachycardia cardiac arrest cardiogenic shock methicillin susceptible pneumonia due to staphylococcus aureus acute pancreatitis 

Answer: The patient is high likely exposed to
