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 49-year-old female, micu call out with history of gestational diabetes transferred from outside hospital with dka and sepsis. the patient was admitted on . there she recalled a history of virus and three days of nausea and vomiting with black material and vomitus. at outside hospital patient had dry mucus membranes and found to be lethargic and tachycardic with o2 sat decreased to 89% on room air. head ct with old infarct, negative chest x-ray, blood glucose 765. at outside hospital had atrial fibrillation and started on diltiazem drip and converted to normal sinus rhythm. blood cultures were positive for gram negative rods. patient started on antibiotics and ceftazidime and cipro and continued on insulin and diltiazem drip. the patient was also found to have pyelonephritis as source of the gram negative rods. cultures initially grew out enterobacter sensitive to cipro. insulin drip was discontinued on , as was diltiazem drip. past medical history: gestational diabetes 7 years ago. allergies: no known drug allergies. transfer medications: ciprofloxacin 400 mg iv bid, protonix 40 mg q d, insulin 35 units q a.m., 17 units q p.m., diflucan 100 mg q d, subcutaneous heparin, magnesium oxide 400 mg , neutra-phos 2 tid, regular insulin sliding scale. social history: positive tobacco use, married. family history: not applicable. physical examination: (on admission) temperature 99, heart rate 96-103, blood pressure 120/59-68, o2 saturation 96-98%. general appearance, pleasant but groggy female in no apparent distress. heent: normocephalic, atraumatic, moist mucus membranes. pupils are equal, round, and reactive to light and accommodation, extraocular movements intact. heart, regular rate and rhythm, negative murmurs, rubs or gallops. lungs, clear to auscultation bilaterally. abdomen, soft, nontender, non distended, normoactive bowel sounds. extremities, no clubbing, cyanosis or edema. pulses 2+ dp. neuro, alert and oriented times three. cranial nerves ii through xii intact. laboratory data: radiology: , head ct negative for bleed. abdominal ct positive bilateral pyelonephritis. chest x-ray times two negative. hospital course: the patient is a 49-year-old female with past medical history significant for gestational diabetes mellitus, presenting in dka. the patient was transferred from the micu in stable condition status post resolved hypernatremia, gram negative rod sepsis due to enterobacter aerogens and bilateral pyelonephritis. while on medical floor, the patient was scheduled for diabetes education from the learning center/ clinic. the patient's ciprofloxacin was converted to po. her protonix was continued and pt evaluated her and deemed her safe for discharge to home. on the patient was very much more improved, tolerating increased po intake and ambulating, vital signs were stable and she was afebrile on po cipro. the patient will follow-up with an appointment with clinic in weeks. the patient will also follow-up with her pcp in one week, dr. . the patient was discharged to home on . condition on discharge: stable. discharge diagnosis: 1. dka. 2. pyelonephritis. discharge medications: lipitor 10 mg po q d, ciprofloxacin 500 mg po q d times 14 days, diflucan 100 mg po q d times three days, protonix 40 mg po q d, insulin nph 28 units q a.m., 14 units q p.m. and regular insulin sliding scale. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified diagnoses: atrial fibrillation hyperosmolality and/or hypernatremia diabetes with ketoacidosis, type ii or unspecified type, not stated as uncontrolled candidiasis of vulva and vagina other specified bacterial infections in conditions classified elsewhere and of unspecified site, other gram-negative organisms acute pyelonephritis without lesion of renal medullary necrosis 

Answer: The patient is high likely exposed to
