[The meadow-field type of tularemia foci in eastern Siberia].

The article characterizes a meadow-type focus tularemia, discovered in Zalarinski'i District of Irkutsk Province in 1988. This focus and another similar focus discovered in 1985 at the Krasnoyarsk Territory belong to the meadow type, which makes it possible to regard their presence in Eastern Siberia as an established fact. The main reservoirs and sources of infection in these foci are two species of voles (Microtus gregalis and M. subarvalis).
