Figure 5From: The spontaneously produced lysogenic prophage phi456 promotes bacterial resistance to adverse environments and enhances the colonization ability of avian pathogenic Escherichia coli strain DE456Bacterial counts during infection in vivo. Chickens were inoculated by the air sac route with strains or a bacteria-phage suspension, respectively. At 24 hpi, chickens were sacrificed and the bacterial load in A lung, B heart, and C liver was quantified. The data was subjected to analysis using the Mann–Whitney U test.Back to article page
