Tick-Transmitted Diseases Caused by Apicomplexa

The objective of this study is to draw attention to Apicomplexa-caused diseases transmitted by ticks. We present ultimate and intermediate hosts of Apicomplexa, including man, as well as vectors transmitting these unicellular Protista. We describe symptoms of Apicomplexa-caused diseases and contemporary methods of diagnostics and therapy. It is noteworthy that the ticks and tick-transmitted pathogenes are distinctly increasing their distribution ranges. Besides, it is important that the ticks are adapted to use many different hosts, including birds, which increases the ticks’ expansion abilities.
