A 12 year old child has been admitted to the ER with severe stomach pain, diarrhea, right side pain, fever, and slight adentitis. The doctors diagnosed with an appendicitis, and proceeded to remove the appendix of the patient. However, 48 hours after the surgery the patient's symptoms still had not subsided the blood cultures, and cultured appendix from the surgery still had not yielded results, and the stool cultures had no yield in terms of enteric pathogens. After 72 hours there was light to medium growth on Blood agar, chocolate agar, and maconkey agar, the colonies are non hemolytic, white, and look like a bulls eye on blood agar, and non-lactose fermenters on maconkey. The gram stain produces gram negative cocco bacilli with some stain retention at the polar ends of the organisms.
They are catalase positive, and oxidase negative.
