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: allergies: imodium a-d / penicillins attending: chief complaint: pseudomembranous colitis major surgical or invasive procedure: subtotal colectomy and ileostomy history of present illness: the patient is a 62 year-old female, transferred from after a four day bout of progressive colitis which did not respond to antibiotic therapy. she was initially transferred to the medicine service and we were consulted. she had a high white count, lactate level and a very tender, distended abdomen. the decision was made to proceed with a subtotal abdominal colectomy. past medical history: pmh: copd, gerd, barrett's esophagus, diverticulitis, ibd, colon polyp, hypertension, hyperlipidemia, hidradenitis, s/p anterior cervical fusion c5-c7, tmj, raynaud's, depression, anxiety. pertinent results: pathology: 1. pseudomembranous colitis, due to c. difficile infection. 2. there is diffuse disease of the cecum and colon, extending to the distal margin. 3. ileal segment, within normal limits. echocardiogram : limited views. the lv is not seen well enough to make a reasonable assessment of either lv function or size. there is a large pleural effusion present. cta chest : impression: 1. no pe. 2. small left pneumothorax. 3. diffuse emphysematous changes. 4. moderate bilateral pleural effusions and associated basilar atelectasis. brief hospital course: ms. is a 62-year-old woman s/p rx with augmentin for uri 2-3 weeks ago who was admitted to () with c. diff pancolitis. on she was transferred to the icu with hypotension (map 60)/sepsis and intubated on with metabolic acidosis (hco3 10). on she had thoracentesis to remove bilateral pleural effusions (600 ml left, 800 ml right). she was transferred to for ?toxic megacolon and ?ischemic colitis. she received a subtotal colectomy with ileostomy on , with no immediate complications and 100 cc blood loss. the morning after the operation sedation was held and she remained unresponsive without spontaneous movement or withdrawal of her extremities to pain. neurology was consulted. ct head: no evidence for intracranial hemorrhage. ct c-spine w/o contrast: significant spinal stenosis with cervical spinal cord compression is present at the c6-c7 level secondary to a large left-sided posterior spondylytic ridge. mri head no evidence of an acute hemorrhage. no acute infarct identified. findings consistent with chronic small vessel ischemia or infarct in the pons and cerebral deep white matter. patient's responsiveness improved over the next several days and lumbar puncture was held. she eventually made a full neurological recovery, delerium cleared, and it is ultimately unclear what the pons pathology seen on mri is attributed to. ortho spine was also consulted and did not see any need for surgical intervention given the c-spine findings. patient was started on tpn. imaging revealed a right-sided pneumothorax as well as rather large pleural effusion, and a right-sided chest tube was placed that drained several liters of fluid over the first several days. this enabled vent weaning and eventual extubation. she was transferred out of the icu on . once bowel function returned she was gradually started on a diet and her tpn was discontinued. her chest tube was removed and she continued to improve clinically. several days prior to discharge she lost iv access and a picc line was placed in ir. later that day the patient became increasingly dyspneic and her hypoxic. cta was performed that did not reveal a pe, and she ruled out for an mi. her picc line was eventually pulled back 4 cm to good effect. ct did however show that her pleural effusions remained and she continues to have an oxygen requirement now at baseline. she is being discharged to rehab on pod11 afebrile, with stable cardiopulmonary, tolerating a full diet, delerium nearly 100% gone. she has completed 12 days of flagyl for cdifficile and is no longer cdiff positive. she will continue for 2 additional days to complete a 2 week course. follow-up with dr. is outlined below. discharge medications: 1. artificial tear ointment 0.1-0.1 % ointment sig: one (1) appl ophthalmic prn (as
