Image of Orientia tsutsugamushi

Description:

This 1976 transmission electron micrograph (TEM) depicted a hypertrophic peritoneal mesothelial cell from mouse that had been experimentally infected intraperitoneally with Orientia tsutsugamushi rickettsial micro-organisms. This micrograph captured an organism as it appeared within a phagocytic vacuole. An outer third membrane, of probable host cell origin, was disintegrating, leaving behind only its electron-dense remnants.
