The degree of infestation of ixodid ticks, collected from humans, with the tick-borne encephalitis virus in the territory of tomsk and its environs


Tick-borne encephalitis (TBE) virus was determined in ticks I. persulcatus and I. pavlovskyi, collected from humans attacked by ticks in city parks, forest-parks in city outskirts, and in suburban forests, by the enzymelinked immunosorbent assay method (ELISA). It was found that, in spite of I. pavlovskyi being the dominating species in Tomsk and its suburbs, the majority of ticks that attacked humans belonged to I. persulcatus. In ticks that possessed no sighs of the beginning of engorgement (hungry ticks), infestation with TBE virus was revealed by ELISA method less frequently. Percentage of I. persulcatus and I. pavlovskyi, infested with TBE virus, constituted 9.43 % and 3.7 %, respectively. In partly engorged ticks, it constituted 48.78 % and 35.0 %, respectively. In suburban forests, humans were also attacked by I. persulcatus more frequently. In this species, the fraction of infested specimens constituted 12.73 % and 41.54 % in partly engorged and hungry ticks, respectively. In I. pavlovskyi, this percentage constituted 6.06 % and 25 %, respectively. In other words, in all the groups examined, the fraction of infested ticks was noticeably lower in I. pavlovskyi; at the same time, the TBE virus is significantly more frequently revealed in partly engorged ticks.
