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: mr. is an 18-year-old male who was brought to the emergency room after a stabbing during an altercation at a party. he was found to have stab wounds in the left buttock and axilla. en route he was found to be unstable and unresponsive. he was resuscitated with recovery of mental status. in the trauma bay, he had hypotension and tachycardia. he was believed to be in shock. he was intubated and a left-sided chest tube was placed, and a trauma ultrasound was performed showing free fluid in morison pouch. past medical history: he has no known past medical history. past surgical history: he has no past surgical history. medications on discharge: none. allergies: no known drug allergies. physical examination on presentation: on examination, he was combative and pale. pupils were equal and reactive. lungs were clear bilaterally. there was a 3-cm laceration in the left axilla, and he was tachycardic. his abdomen was mildly distended without tenderness. there was a 5-cm laceration on the left buttock with active bleeding. rectal showed normal tone. his extremities were cool, modeled, and he had weak distal pulses. pertinent laboratory data on presentation: his initial laboratory results in the trauma bay revealed a white blood cell count of 6.6, hematocrit of 31, platelets of 216, and an inr of 1.6. his chemistries were remarkable for a creatinine of 1.5 and a glucose of 380. his toxicology screen was remarkable for an ethanol level of 132. initial blood gas was 7.05/43/439/13 and -18 with a lactate of 11.4. hospital course: he was taken to the operating room emergently for an exploratory laparotomy. in the operating room, the patient underwent an exploratory laparotomy with control of left iliac bleeding, control of hepatic laceration, packing of the abdominal cavity, and a segmental resection of the rectosigmoid area of perforation. the bowel was left stapled as a hartmann and was a blind end and was not matured as an ostomy. there was a question of nerve injury to the lumbosacral plexus. the patient left the operating room and was taken to the intensive care unit for further resuscitation and stabilization. it was opted not to close his abdomen or mature stoma at the time. over the course of the next day in the intensive care unit, the patient remained critical. he was sedated with morphine and ativan drips, and paralyzed with cisatracurium and placed on protonix prophylactically. he received ancef and flagyl for perioperative coverage. he returned to the operating room on postoperative day one for removal of his packs. there was no further bleeding, and his fascia started to be closed partially. again, the argon beam coagulator was used to achieve hemostasis. he was returned to the intensive care unit for further management. lower extremity noninvasives studies revealed no evidence of deep venous thrombosis. he was returned to the operating room again on for further closure of his abdominal wound. he was returned to the operating room again on for further abdominal wall closure, maturation of colostomy, and v.a.c. dressing placement. total parenteral nutrition was initiated for metabolic support. antibiotics were narrowed to kefzol alone. antibiotics were then switched to vancomycin to cover gram-positive cocci in his sputum gram stain. levofloxacin was subsequently added for gram-negative rods in sputum culture which eventually were identified escherichia coli. the patient remained critically ill in the intensive care unit and on aggressive ventilatory support, nutritional support, and antibiotics. on , he was noted to have left upper extremity edema. a left upper extremity ultrasound revealed left internal jugular thrombosis. a previously placed central line had a positive tip, and it had been removed. after his abdominal wall closure, his abdomen was found to be soft but tight with bladder pressures ranging from 20 to 30. urine output was adequate, and this pressure subsequently resolved over time. on , he had an abdominal ultrasound that showed pelvic fluid collections which were not drained at that time. on , a ct of the abdomen revealed a left lower quadrant abscess and a pigtail drain was placed. on , a pigtail was placed in the right lower quadrant, and he was found to have an evolving liver hematoma. on , he returned to the operating room for exploratory laparotomy for spiking fevers and elevated white blood cell count. there was an area of hepatic necrosis that was cultured but not debrided. drains were placed, and the abdomen was closed with v.a.c. dressing once again. throughout this time, the only significant cultures were escherichia coli and yeast from the sputum. antibiotics remained vancomycin and levofloxacin. an infectious disease consultation was obtained on . they encouraged changing from levofloxacin to zosyn as well as culturing chest tube drainage. a workup of his fever and white blood cell count included a transesophageal echocardiogram that showed no evidence of an endocarditis and normal left ventricular function. the patient was finally taken back to the operating room on for exploratory laparotomy for these spiking fevers and elevated white blood cell counts. it was noted that the hepatic necrosis was drained but not debrided. fluconazole was also added for yeast coverage. early in the morning on , the patient was found to have bleeding from the penrose drain in his left buttock incision. there was no active bleeding at the time of examination. his hematocrit was found to be down from 24 to 21. a ct scan obtained at that time showed evidence of extravasation from the left internal iliac branch. the patient subsequently went to angiography for embolization of a left gluteal pseudoaneurysm. embolization was successful with complete occlusion of the av fistula and hemodynamic stability following the procedure. tube feeds were also started on ; however, total parenteral nutrition was continued to provide adequate nutritional support. the patient's ventilatory mode was changed over to cpap pressure support, and he weaned well. a follow-up abdominal ct on showed a collection in the left hemipelvis, and a pigtail was placed under ct guidance. vancomycin was added back to the antibiotic regimen on from gram-positive isolated just from blood. a ct of the abdomen on , for continued fever and elevated white count, showed no new collections. a follow-up ct on was similar. a ct venogram done at that time was negative, and a duplex of the lower extremities was also negative. cultures from his various drains over the next two weeks subsequently grew escherichia coli and bacteroides sensitive to levofloxacin and flagyl. his antibiotics were tailored appropriately. he was extubated on , and he was started on sips, and the psychiatry service consulted for support. of note, the patient had been on subcutaneous heparin, heparin in his total parenteral nutrition, and then subsequently lovenox for deep venous thrombosis prophylaxis. he was transferred to the floor on where his diet was advanced slowly. he continued to work with physical and occupational therapy. on the evening of , the patient was found to be tachypneic and hypertensive. a chest x-ray was unremarkable. however, given his significant history, a ct angiogram was performed of the chest to rule out pulmonary embolism. this was negative, but it was decided that the patient would return to the intensive care unit for closer monitoring. a ct of the head was also performed for question change in mental status, and it was negative. another ct of the abdomen was performed with placement of yet another pigtail drain in the left pelvis. he was transferred back to the floor on where he continued to work with physical therapy. he was noted to have a left foot drop, and a brace was created to aid in positioning. he was on levofloxacin and flagyl. he remained stable with no fevers and a normal white blood cell count. a follow-up ct scan on with injection of the drains showed a question of communication of the drains with the small bowel, but no further collections to be drained. his drains were removed on . on , as the patient remained afebrile with a normal white blood cell count and had managed to take adequate p.o., he was discharged to home. he was to complete three more days of levofloxacin and flagyl. he was scheduled for home physical therapy and instructions to follow up in the trauma clinic. of note, on renal was consulted for the patient's persistent hypertension. they felt this was likely related to his current illnesses and recommended an outpatient workup. his antihypertensives were discontinued, and he was discharged to home on pain medications and antibiotics as outlined above, and with arrangements for home occupational and physical therapy. he was also discharged home on lovenox for deep venous thrombosis prophylaxis for six weeks' time. , m.d. dictated by: medquist36 procedure: insertion of intercostal catheter for drainage continuous invasive mechanical ventilation for 96 consecutive hours or more
