Twenty patients on a surgical ward develop urinary tract infections after catheterization. In each instance, the isolated organism grows sheep blood agar as a large, gray colony, and on MacConkey agar as a large, flat, pink colony. The oxidase-negative, gram-negative rod produces the same biotype and is resistant only to tetracycline. Additional biochemical results are as follows: Phenylalanine deaminase (PAD): negative Urease: negative Hydrogen sulfide (H2S): negative Lysine decarboxylase: positive Ornithine decarboxylase: positive Indole: positive Citrate: negative
