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: medications on admission: atenolol 50 mg by mouth once daily. history of present illness: this is a 54-year-old woman with a chronic history of kidney stones, who presented to the emergency department complaining of fatigue, dizziness, bilateral upper quadrant pain of a several week duration. her acute complaint, however, was inability to urinate and left flank pain of approximately four days' duration. in the emergency department, her examination was notable for being afebrile, with tender bilateral upper quadrants as well as left costovertebral angle tenderness. her laboratories were notable for a white count of 27.6, a bun of 53, and a creatinine of 3.7. her urine was grossly hematuric. a ct scan of her abdomen and pelvis was performed, which revealed mild hydronephrosis on the left, as well as mild hydroureter nephrosis on the left with a 2 mm ureterovesical junction stone. hospital course: given the patient's acute renal failure being apparently secondary to obstruction, the decision was made to take the patient to the operating room for placement of a stent and removal of stone. the patient went to the operating room and had a 6 x 26 double-j open-ended ureteral stent placed in her left ureter. pyonephrosis was noted during the procedure, as well as a fair amount of hemodynamic lability with systolic pressures falling into the 80s. the patient was, however, stable enough for extubation, and was transferred to the post-anesthesia care unit with systolic pressures in the 90s. postoperatively, however, she developed hypotension again, as well as a tachy/brady type of heart rate. she became acidotic and, as it was apparent that the patient was in urosepsis with multifactorial acute renal failure, the patient was transferred to the intensive care unit for stabilization. once there, the patient had a triple-lumen catheter placed. she had a cvp of 9, as well as a hematocrit of 25. therefore, she was transfused with two units of packed red blood cells. she developed bibasilar crackles on her lung examinations, along with needing an increasing oxygen supplementation. a chest x-ray was performed at that time, which demonstrated failure physiology. cardiology was consulted, and they performed a transthoracic echocardiogram which demonstrated mild left ventricular as well as right ventricular hypokinesis with an ejection fraction of approximately 50%. blood cultures subsequently grew out e. coli, and she was begun on ampicillin and ceftriaxone. by postoperative day four, the patient had stabilized and she was transferred to the floor. the remainder of her postoperative course was uneventful. she was started on lasix with good effect to reduce her oxygen requirements. however, she developed hypokalemia, which needed repletion through her central venous line. magnesium was also repleted, and her central venous line was discontinued. she was weaned off of her oxygen requirement and, by postoperative day five, the day of her discharge, her oxygen saturation was 94% while breathing room air. she was otherwise well recovered, remaining afebrile, with stable vital signs, making good urine and with a return of her bowel function, tolerating a house diet. the patient was subsequently discharged home in stable condition. discharge diagnosis: 1. urosepsis secondary to renal lithiasis of the left kidney with resultant pyonephrosis discharge medications: potassium chloride 40 mg by mouth once daily, atenolol 50 mg by mouth twice a day, levofloxacin 500 mg by mouth once daily, asa 81 mg by mouth once daily, lasix 20 mg by mouth once daily. , md dictated by: medquist36 procedure: venous catheterization, not elsewhere classified ureteral catheterization transfusion of packed cells retrograde pyelogram transurethral removal of obstruction from ureter and renal pelvis diagnoses: other primary cardiomyopathies acidosis urinary tract infection, site not specified acute kidney failure, unspecified unspecified septicemia other shock without mention of trauma hydronephrosis 

Answer: The patient is high likely exposed to
