[Epizootological assessment of the possibilities of importing plague from Vietnam to Russia].

To assess whether the plague microbe with vectors or carriers can be imported from Vietnam to Russia, the authors consider the specific features of pathogen circulation in this country's biotopes varying in anthropogenic transformation. The idea that there were natural foci of plague in Vietnam dominated until the late 1990s. The small rat Rattus exulans that inhabits open stations and ensures a parasitic contact with the synanthropic representatives of the fauna was considered to be a major carrier.

[Natural foci of plague in India: epizootological characteristics].

In the first half of the 20th century, India was responsible for the incidence of plague in both Asia and the world. The early 21st century was marked by two new epidemic outbreaks of plague (in 2002 and 2004) in this country. The major characteristics of plagues in India, activation of which is a cause of new epidemic outbreaks and necessitates a continuous epizootological monitoring, are analyzed.

In China plague has been officially registered from 1754 (638 epidemics with total number of cases 2.5 millions and case-fatality rate 87.5%).

[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.
