Image of Orientia tsutsugamushi

Description:

This 1978 transmission electron micrograph (TEM) depicted a brain capillary of a mouse that had been experimentally infected intravenously with Orientia tsutsugamushi rickettsial micro-organisms. This TEM revealed that one organism was budding from the luminal surface of a hypertrophic capillary endothelial cell, still covered by a third layer consisting of the host cell's plasma membrane. Others are visible free within the endothelial cell's cytoplasm.
