Features reovirus RNA isolation from clinical material S. A. Kolpakov, E. P. Kolpakova. Key objective of the given research is to find out reasons of failures during extraction of the RNK reoviruse from sick people clinical material. In due course it was discovered that transcriptase (RNA dependent RNA polymerase) very quickly transforms double-stranded RNA into a single-stranded RNA due to short time of activation after violation of reoviruse outside capsid integrity. This single-stranded RNA is invisible using standard way of electrophoresis registration. Addition of a transcriptase with polymerase function in ready-made samples or in clinical material from sick people before RNA extraction leads to transformation of a single-stranded RNA (if available) into a dsRNA identified after electrophoresis in the form of genome’s segments. The developed RNA visualisation method could assist in etiological diagnostics of reoviral infection and in studying of reovirus as a pathogen.

The structure of the information system of the GIS as an internet-based resource and its application for solving practical problems are described. For the first time in Russia, the GeoRSS standard based on the structured hypertext representation of the geographic and attribute information has been applied in the state system for the agromonitoring of agricultural lands in Rostov oblast and information exchange through the internet.

Resistance of microorganisms to antimicrobial drugs Pokudina Inna Olegovna, Shkurat Mihail Alekseevich, Battalov Dmitrij Valentinovich Abstract: The emergence of the phenomenon of resistance to therapeutic drugs in the pathogenic microorganisms, has a very negative effect on the health of humanity, because it leads to a sharp decrease in the efficiency of etiotropic therapy  of infectious diseases. Intense selective pressure of antibiotics leads to the rapid evolution and spread of new resistance mechanisms in health care settings and, above all, in the Intensive care unit. The article analyzes the literature data about the mechanisms of emergence and transmission of the resistance of pathogens to antimicrobial agents and acquired resistance associated with the production of beta-lactamases extended spectrum.

Differentiation of ground invertebrate communities in urban environment (Kaluga, Russia) We have collected arthropods with pitfall traps and identified them to order or to family. Classification of arthropod communities reflects habitat properties, if we survey herpetobionts sensu lato (as biocenotic layer). And there is no satisfactory classification, if we consider herpetobionts sensu stricto (as life form). Differentiation of arthropod communities in urban area is influenced mainly with density of canopy.
