FIG 5.

(a) Survival rates of mice treated with ceftriaxone alone or ceftriaxone combination therapy after V. vulnificus intestinal infection. Survival rates for the ceftriaxone-doxycycline (*, P ≤ 0.05) and ceftriaxone-ciprofloxacin (**, P < 0.01) groups were significantly higher than those for the ceftriaxone group. (b) Survival rates of mice treated with cefepime alone or cefepime combination therapy. Survival in the cefepime-doxycycline (****, P < 0.0001) and cefepime-ciprofloxacin (***, P < 0.001) groups was significantly higher than that in the cefepime group.
