[The rate of infection of the taiga tick with Borrelia in the western Sayan].

The paper provides microscopic findings of taiga ticks collected for the causative agent of Lyme's disease in May to July 1993 in the West Sayan . A total of 1,016 specimens were examined, among them 124 (12.2%) were found to have Borreliae. The areas were demonstrated to vary greatly with their epidemiological risk. The number of ticks and hence the epidemiological risk were the most in the low-mountain and chern taiga areas.
