This member of the Enterobacteriacea gave these reactions: H2S (TSI) Negative Ornithine Negative Lysine Positive Citrate Positive Urea Positive Phenylalanine Negative Motility Negative What is this organism?

A gram-negative rod from a stool culture produces red colonies (colorless) with black centers on xylose lysine decarboxylase (XLD) agar. When the organism is inoculated to triple sugar iron agar (TSIA) and lysine iron agar (LIA), it should appear as which of the sets of tubes shown in the image?

The acid/acid reaction shown in the photograph of a Triple Sugar Iron (TSI) Agar reaction tube indicates the recovery of a bacterial species that ferments both glucose and lactose. Also, is the absence to the formation of any black pigment which indicates one of the Enterobacteriaceae that does not produce hydrogen sulfide (H2S). Select the species producing this acid/acid, H2S negative reaction.
