摘要: Paenibacillus larvae is the causative agent of American foulbrood (AFB), most serious honey bee brood bacterial disease. We isolated and characterized P. larvae-directed bacteriophages developed criteria for safe phage therapy. Whole-genome analysis a highly lytic virus family Siphoviridae (HB10c2) provided detailed safety profile uncovered its lysogenic nature putative beta-lactamase-like protein. To rate antagonistic activity against pathogens targeted to specify potentially harmful effects on population environment, genotypes ERIC I IV, representatives gut microbiota, broad panel members order Bacillales were analyzed HB10c2-induced lysis. Breeding assays with infected revealed that in vitro observed was not predictive real-life scenario therapeutic efficacy. On basis disclosed larvae-bacteriophage coevolution, we discuss future prospects AFB
