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: patient recorded as having no known allergies to drugs attending: chief complaint: bloody diarrhea x 2 weeks major surgical or invasive procedure: colonoscopy x 2 (+1 failed poor prep) tagged rbc gi bleeding study history of present illness: 83yo woman with h/o diverticulosis, c. diff who presents with bloody diarrhea for 2 weeks. states is constipated at baseline (1 bm qod), and has a h/o hemorrhoids so she initially thought her bloody diarrhea was hemorrhoidal bleeding. her bm frequency increased to 2-3bm's day from baseline. the color was darker than normal for her. the diarrhea was unusually malordorous. she came to because she just wasn't getting better and was fed up with wearing sanitary pads. also worried because her sister passed away from colon ca last year (age 81). denies any abdominal pain or n/v. no cp, no sob. she has been tolerating pos normally but notes a slightly decreased appetite and weight loss of 5 pounds. feels tired and weak but denies dizziness or lightheadedness. no recent hospitalizations but was hospitalized last year in for pneumonia, developed c. diff which required 3 months of treatment. . in the er she was found to have a hct of 38 (baseline), she had guaiac positive melena on exam. she received 1l ns. gi was called and recommended ct abdomen with contrast, which was negative for colitis, showed patent arteries, and showed diverticulosis without diverticulitis. they recommended colonoscopy in am, and she was begun on golytely prep. however, the patient did not tolerate this and was changed to mag citrate. she also received 1 unit of prbcs. . on admission to the fllor she feels well but weak. bms are still dark, mixed with blood. past medical history: pmhx: - htn - ppd positive - bronchiectasis - c diff after hospitalization for pneumonia - colonoscopy with 2 adenomas and 2 hyperplastic polyps, diverticulosis -- due for next scope in - macular degeneration social history: lives home with friend. retired ge worker. walking for exercise is limited by her breathing trouble with bronchiectasis. no tobacco, rare etoh, no other drugs. family history: sister died of colon ca last year (was in her 80s), brother with mi, brother with valve replacement physical exam: t: 96.3 bp: 104/58 p: 68 rr: 20 o2 sats: 92% ra gen: nad, pleasant, conversant heent: ncat, perrla, mmm neck: soft, no lad cv: rrr, no m/r/g, s1s2 resp: ctab abd: soft, nt, nd, +bs, no hsm guaiac: pos melanotic per er ext: no c/c/e, 2+dp pulses bilat neuro: sensory grossly nl, strength 5/5 ble/bue, cn 2-12 intact pertinent results: blood wbc-10.1 rbc-4.39 hgb-13.3 hct-38.3 mcv-87 mch-30.2 mchc-34.7 rdw-13.5 plt ct-459*# rpt hct-32.0* . wbc-9.2 rbc-2.88* hgb-8.7* hct-24.8* mcv-86 mch-30.2 mchc-35.1* rdw-13.9 plt ct-281 wbc-13.0* rbc-3.32* hgb-10.2* hct-28.6* mcv-86 mch-30.6 mchc-35.5* rdw-14.0 plt ct-343 . wbc-9.6 rbc-2.72* hgb-8.2* hct-24.2* mcv-89 mch-30.1 mchc-33.9 rdw-14.0 plt ct-336 pm hct-32.2*# . wbc-9.1 rbc-3.12* hgb-9.6* hct-27.6* mcv-88 mch-30.9 mchc-35.0 rdw-14.4 plt ct-294 . pm hct-33.0* . wbc-7.3 rbc-2.72* hgb-8.5* hct-24.3*# mcv-89 mch-31.1 mchc-34.8 rdw-14.5 plt ct-272 . cardiac enzymes ck-mb-notdone ctropnt-0.14* ck(cpk)-90 . ck-mb-notdone ctropnt-0.08* ck(cpk)-36 . 12:20 pm stool consistency: soft **final report ** clostridium difficile toxin assay (final ): feces negative for c. difficile toxin by eia.
