Isolation of a Rickettsial Pathogen from a Non-Hematophagous Arthropod
Figure 4
Electron micrographs of Rickettsia isolated from booklice in ISE6 cells.
(A) Typical infected cells containing rickettsiae in cytosol. (B) Typical ultrastructure of Rickettsia. Inset: higher magnification view of rickettsial cell wall including trilaminar cell wall associated with the external surface microcapsule layer (solid arrows) and an internal trilaminar cytoplasmic membrane (arrowheads). m represents mitochondria. (C) Rickettsiae surrounded by a halo zone (h). (D) Rickettsiae being destroyed in a phagolysosome. Long arrows indicate phagolysosomal membrane. Bar = 500 nm.
