Image of Orientia tsutsugamushi

Description:

This 1976 transmission electron micrograph (TEM) depicted a hypertrophic peritoneal mesothelial cell of mouse that had been experimentally infected intraperitoneally with Orientia tsutsugamushi rickettsial micro-organisms. This micrograph showed one organism as it was in the process of budding from the luminal cell surface, still covered by a third layer, consisting of the host cell's plasma membrane. Others are visible free within the host cell's cytoplasm.
