Moderately satisfied ecological condition for the biodiversity of Lake Sevan basin-s rivers has been established, and the changes in species- composition of zoobenthos in Lake Sevan were detected. A growing tendency of antibiotic resistance among E. coli isolates in water resources has been shown. ER -
