Virus-like Particles in Rickettsia within the Midgut Epithelial Cells of Glossina morsitans centralis and Glossina brevipalpis

Abstract The midgut epithelium cells of both teneral and 30-day-old nonteneral Glossina morsitans centralis and Glossina brevipalpis contain nonoccluded, isometric virus-like particles (VLPs) of 40 nm maximum diameter, within a proportion (
