Abstract
A virus unrelated to any other from bees was isolated from diseased adults of Apis mellifera from Egypt. It has isometric particles about 30 nm in diam., which contain RNA and sediment at 165S. The particles contain three proteins, have a buoyant density in CsCl of 1.37 g/ml, aggregate readily in low concentrations of buffer or at low pH values, form ‘empty’ shells below pH 5.0 and disintegrate below pH 4.0.
Three virus isolates closely related to each other and to Kashmir bee virus were obtained from dead adults, larvae and prepupae of Apis mellifera from South Australia, New South Wales and Queensland. Particles of the four strains are physically indistinguishable and each contains three proteins, but two proteins of the Australian strains differ from those of Kashmir bee virus in estimated size and stability.
