title: The ultrastructure of Rickettsia slovaca in naturally infected females of the tick Dermacentor marginatus.
abstract: The ultrastructure of Rickettsia slovaca in naturally infected females of the tick Dermacentor marginatus is similar to that of other members of the spotted fever group rickettsiae. R. slovaca was found to multiply in all organs, tissues and cells examined. It is primarily found free in the cytoplasm; occasionally it may also invade the cell nucleus. Special attention was paid to the rickettsiae in the salivary gland. They multiply in all cells of the three acini types I-III and also in the duct cells. The amount of rickettsiae eliminated via the saliva reached values of about 10(4)EID50/ml.
