Adult honey bees (Apis mellifera Linnaeus) appeared normal 12 days after injection with purified sacbrood virus (SBV). Five days after injection viral inclusions were observed in thin sections of fat-body tissue from injected bees. The kinds of cytoplasmic inclusions that were found probably reflect different stages of infection. © 1967.
