In this study, we analyzed the transcriptomes of RNA and DNA viruses from the oligotrophic water of Lake Baikal and the effluent from wastewater treatment plants (WWTPs) discharged into the lake from the towns of Severobaikalsk and Slyudyanka located on the lake shores. Given the uniqueness and importance of Lake Baikal, the issues of biodiversity conservation and the monitoring of potential virological hazards to hydrobionts and humans are important. Wastewater treatment plants discharge treated effluent directly into the lake.

The cyanobacterium sp. has formed massive fouling on all types of benthic substrates, including endemic Baikal sponges.

The microcystin synthetase genes belonged to the genera , and possibly spp. No microcystins were found in the water of the lake.

Since 2011, the process of colonisation of the lake with potentially toxic cyanobacteria belonging to the genus has continued. An understanding of the mechanism of successful expansion of requires scrutiny of biological and genomic features.
