However, after detecting the gram-negative rods, antibiotic therapy was changed to intravenous tazobactam/piperacillin (4.5 g; 3 times/day) administration as we suspected Pseudomonas aeruginosa-mediated skin infection (Fig. 1).
(A) Vibrio cincinnatiensis colonies were observed as beta-hemolytic and oxidase-positive gram-negative rods on 5 % sheep blood agar after incubation for 20 h at 35  C. (B) Vibrio cincinnatiensis showed poor growth on bromothymol blue (BTB)-lactose agar and (C) small, green colonies appeared on thiosulfate-citrate-bile-salt-sucrose agar after incubation for 16 h at 35  C.
