In vivo study was conducted to evaluate the efficacy of bacteriophages in reducing the pathogenicity of single and mixed infections with APEC and IBV. In the present study samples were collected from birds with respiratory manifestations from a total of forty farms, and subjected to characterization based on currently circulating IBV and APEC strains. In addition, the efficacy of bacteriophage treatment in reducing APEC replication in the avian respiratory tract was studied in vivo, as well as their effect in reducing IBV pathogenicity after mixed APEC and IBV infections. ./cache/cord-308591-cs8os2f5.txt ./txt/cord-308591-cs8os2f5.txt
