Abstract: | 10 strains of Francisella tularensis were isolated from 4 species of gamasid mites, Laelaps muris, L. multispinosus, Hyperlaelaps amphibius and Haemolaelaps glasgowi, in natural nidi of tularemia in the Tumen district. Under experimental conditions L. muris is often infected with tularemia agent on sick animals but preserves it at an indoor temperature not more than a week and does not transmit it transovarially. Haemogamasus ambulans preserve the agent within the same period. L. muris and Hirstionyssus isabellinus do not transmit the tularemia agent to healthy animals through a bite. |
