Comparative susceptibility and immune responses of Asian and European honey bees to the American foulbrood pathogen, Paenibacillus larvae

American foulbrood (AFB) disease is caused by Paenibacillus larvae . Currently, this pathogen is widespread in the European honey bee— Apis mellifera . However, little is known about infectivity and pathogenicity of P. larvae in the Asiatic cavity‐nesting honey bees, Apis cerana . Moreover, comparative knowledge of P. larvae infectivity and pathogenicity between both honey bee species is scarce. In this study, we examined susceptibility, larval...
