Lethality of ICR mouse for intraperitoneal inoculation with APEC isolates and human ExPEC strains.

a

Negative control for mouse sepsis model.

b

Positive control for mouse sepsis model.

c

Data mean the number of dead mouse/total number of mouse tested.

d

Data mean the number of mouse from which the APEC/ExPEC strain was reisolated/total number of mouse tested.

e

Mean of lesion scores (1 = healthy, 2 = minimally ill, 3 = moderately ill, 4 = severely ill, 5 = dead) for 10 mouse tested.

f

Values are not significantly different (P≥0.05 by Fisher's exact test) with the negative control.
