ABSTRACT
The paper gives the results of a study dealing with the detection of the antigens of arboviruses of West Nile, Sindbis, Batai, Crimean-Congo hemorrhagic fever, a serocomplex of Californian encephalitis in the field material gathered in the Saratov Region in 2000-2006. The bloodsucking arthropods inhabiting the region were shown to be actively involved in the circulation of arboviruses in natural biotopes. The conclusion that it is expedient to organize an annual monitoring of arbovirus-induced infections in the areas where positive findings have been notified is justified.

The paper analyzes relationships of the plague bacilli to the representatives of different types of living organisms inhabiting the burrows. The authors give their own data on the qualitative and quantitative composition of indicoles of the burrow of little sousliks (Spermophillus pygmaeus). They assess the role of mutagenic agents in burrow microbiocenoses.
