Abstract:

Immature stages of ixodid ticks, D. pavlovskyi, H. warburtoni, and H. punctata, were infected with plague under experimental conditions. However, the infection rates were not similar. The highest infectivity percentage was obtained from D. pavlovskyi, in which the developmental cycle of the tick is one year. In D. pavlovskyi larvae and nymphs, the plague microbe was revealed on the first day after termination of feeding on an infected animal. Duration of preservation of plague microbe in larvae amounted to 19 or 20 days, and possibly longer. Transstadial transmission of the plague agent from larva to nymph and from nymph to adult was not obtained in the experiments. Author
