These images are from the culture of an expectorated sputum specimen from a 77 year old patient suffering from symptoms of pneumonia (BAP on the left, MAC on the right, growth on CHOC resembles BAP). Further biochemical testing indicates that the pathogen is: Indole = pos oxidase = neg MR = pos lysine = neg VP = neg arginine = neg Citrate = neg ornithine = neg Tryptophan deaminase = pos urea = pos TSI = A/H2S nitrate = pos ONPG = neg
