Prevalence of TBEV in I. ricinus (I. ric), I. persulcatus (I. pers), and hybrid (Hybr) ticks at different period after feeding/molting: (A) in engorged larvae (LL) and nymphs (NN) after feeding on infected mice; (B) in questing nymphs (NN) and adults (Ad) after first molting; (C) in adults after second molting. Data for the strains EK-328 and LK-138 are separated with dashed line. Engorged larvae and questing nymphs were studied in pools of three, others – individually, TBEV prevalence in a pool of ticks was calculated using a maximum likelihood estimator with the assumption of 100% test sensitivity and specificity on the EPITOOLS web platform (Sergeant, 2018). Whiskers show 95% confidence interval of the infection rate; significant differences between groups according to Fisher’s exact test/chi-square test: * p<0.05, ** p<0.001.
