A 82 year-old woman is admitted to the hospital from an assisted living facility with mental status changes, fever, urinary frequency and abdominal pain. Urinalysis dipstick indicates a positive leukocyte esterase, WBC, RBC and positive nitrate. Urine culture grew > 100,000 colonies/ mL of large grey colonies on BAP and clear colonies on MAC. Based on the following biochemical reactions, what is the likely cause of the patient’s UTI? Indole = pos MR = pos Citrate = neg Urea = hot pink TSI = K/A Ornithine = pos PAD = pos Sucrose = neg Mannitol = neg Adonitol = neg

Given the following biochemical reactions, identify the organism. TSI = K/H2S ONPG = neg Citrate = neg Motility = pos Indole = pos Moeller Lysine = purple Moeller Ornithine = purple Moeller base = yellow MR / VP = pos / neg Mannitol = neg PAD = neg

An outbreak of severe diarrhea occurred 12-72 hours after a holiday party where the gazpacho was linked to infection in almost everyone who attended. In stool cultures from the patients the pathogen grew medium to large clear colonies on MAC and XLD plates. Based on the additional biochemical reactions below, what is the most likely identification of the organism causing the outbreak? Citrate = negative Indole = negative Mannitol = positive Motility = negative Moeller Lysine = yellow Moeller Ornithine = yellow Moeller Base = yellow MR = positive ONPG = negative Oxidase = negative PAD = negative TSI = K/A Urea = negative
