Hello, I am a Microbiology student with a case study assignment. The case is a 4yr old female presents to the emergency room with bloody diarrhea fever and vomiting. Patient has had symptoms x24hrs with no urine production in that time. Hx: Pt. went on a field trip to the local fair grounds, went into a petting zoo and had a lunch of ground beef burgers, fries and milk. This trip was 4 days prior to symptoms. We have Labs of decrease in kidney function, lysed RBCs. Micro samples show Gram negative rod that grows in single arrangement. It is catalase positive and is a lactose fermenter with peritrichous. Also, patient has a temp of 39C. Is this disease e-coli? If not what is it? Thank You
