Given the following reactions, chose the best answer to identify the organism. MAC = Clear colonies Citrate = Positive Urea = hot pink VP = Negative TSI = Red/Yellow PAD = Green after FeCl3 DNase = Negative Ornithine = negative Motility = Positive Inositol = Positive Indole = Positive Adonitol = Positive

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
