ON POSSIBLE REASONS FOR VIRULENCE CHANGES IN AN IXODES PERSULCATUS POPULATION,

Abstract

There is an apparent association between increased virulence in I. persulcatus and the recurrent increase in host numbers of forest tick nymphs, which are characterized by a very high infestation rate. It is interesting to note that tick virulence dynamics in the observation area entirely coincided with the dynamics of tick infection with tickborne encephalitis. These may be explained only by considering similar sharp changes in the composition and number of hosts of the forest tick, as well as partially by the migration of Manchurian squirrels. (Author)
