Přítomnost nízkomolekulárních imunomodulátorů ve slinách klíštěte \kur{Ixodes ricinus}
HAUSEROVÁ, Simona
Ticks use proteinaceous molecules contained in their saliva to suppress immune response of the host to complete their succesful feeding. In some ticks (e.g. Rhipicephalus sanguineus) presence of non-proteinaceous molecules was discovered. The aim of this work was to determine the amount of these molecules in the saliva of Ixodes ricinus tick. Namely, prostaglandin E2 and adenosine were analyzed. The second aim of this work was to evaluate the role of both low molecular weight components (or at least one of them) in the suppression of TNF-alfa cytokine production in suitable cells by ticks saliva.
Comparison of various ways of tick infection with the tick-borne encephalitis virus
VÝLETOVÁ, Eva
The aim of the bachelor thesis was to compare various methods of Ixodes ricinus tick infection with the tick-borne encephalitis virus. For infection by immersion method, less virulent TBE virus strain Neudoerfl was used resulting in 5 % of infected ticks. Using more virulent strain Hypr provided 60 % of infected ticks. 75 % of ticks became infected with the Neudoerfl virus by capillary feeding. Infection of ticks by feeding on viraemic mice was unsuccessful. Applicability of tested methods for infection of tick life stages is discussed.
