Investigations of ticks for the presence of Borrelia in Czechoslovakia.
More than 570 ticks from different parts of the country were studied microscopically. In 45 cases (8%) Borreliae were found. The infectivity rate of ticks in different foci varied from 3-11%, in some instances nearly 20%. Only Ixodes ricinus, male and female ticks were positive in this study.
