The efficacy of a bacteriophage on mortality rate of chicken E. coli challenged. NC: negative control, without E. coli, without phage; PC: positive control, E. coli challenged, without phages; NC+MHH6 and NC+PR2: negative control plus MHH6 or PR2 phage, respectively; PC+MHH6, PC+PR2: positive control plus MHH6 or PR2 phage, respectively; PC+MHH6PR2: positive control plus both MHH6 and PR2 phages.

(a) Heart; (b) Liver; (c) spleen; PC: positive control, E. coli challenged, without phages; PC+MHH6, PC+PR2: positive control plus MHH6 or PR2 phage, respectively; PC+MHH6PR2: positive control plus both MHH6 and PR2 phages.
