FIG. 2.

Dose effect of phage ENB6 in rescuing mice from lethal VRE bacteremia. The mice were scored for their state of health as described in the text. Each bar indicates the state of health of mice after i.p. administration of the MLD of VRE followed by a single dose of phage at the indicated concentration 45 min after the bacterial challenge.The group on the far right (four mice) was an untreated control, given SM buffer i.p. instead of phage. The group on the far left (two animals) was a phage control, injected only with phage (at the high dose) and not infected with bacteria, in order to determine if the phage preparation itself produces adverse effects in mice.
