Toxic effect of endocytobionts from Dermacentor reticulatus ticks in three tick species after in vivo application.

The endocytobionts from ovaries of partially engorged female Dermacentor reticulatus ticks, inoculated introcoelomally into females of three tick species, D. reticulatus, Ixodes ricinus and Haemaphysalis inermis, caused considerable morphological alterations in the examined cells and tissues of the synganglion, fat body, tracheal complex and ovary of these recipients.
