Marine viruses

Viruses are important components in marine ecosystems and play key roles in microbial evolution and biogechemical cycling. Further, viruses are used in disease control. We investigate these aspects of viral activity from field studies and by experimental studies of virus-host interactions under controlled conditions in the laboratory.

Marine viruses are intracellular parasites of mainly heterotrophic bacteria, and the most abundant biological components in the marine environment. At Marine Biological Section we study the ecology of marine viruses and their bacterial hosts and explore the potential of using viruses to control pathogenic bacteria.
