case_images: Edwardsiella tarda recovered from patient blood. (A, B) Isolate growth after 36 hours incubation. (A) Colonies on sheep blood agar. Colonies exhibit beta-hemolysis with distinct zones of clearing on plate reverse. (B) Colonies on MacConkey agar. Colonies remain colorless due to inability to ferment lactose. (C) Gram stain showing straight gram-negative rods, 1000X magnification. (D) From left to right: positive urease control (Klebsiella pneumoniae), E tarda negative urease, uninoculated triple sugar iron (TSI) slant, E tarda TSI slant with K/A, Gas, H2S result. Arrows point out gas bubbles. (E) Spot oxidase test E tarda negative result (no color change to violet). (F) Spot indole test E tarda positive result (color change to turquoise-blue).
