[Does the suction biting of uninfected ixodid ticks protect against tick-born encephalitis in subsequent bites?].

It has been experimentally established that suction of noninfected preimago and imago of Ixodoidea to sensitive animals (e.g. white mice) does not lead to the elaboration of immunity protection from bites of insects infected with tick-borne encephalitis virus. A protecting effect may be manifested in decreased likelihood (incidence) of repeated suction to animals formerly bitten by ticks.
