Scientists from Russia, Austria, and the USA have discovered virus-like particles in the bacterial symbionts of Bryozoa - a phylum of colonial aquatic invertebrates - filter-feeders dominating in many bottom ecosystems. The research project was planned and supervised by scientists from St Petersburg University. Some of the virus-like particles resemble red blood cells, while others have a sea-urchin-like appearance. Although viruses have never been reported inside symbiotic bacteria in bryozoans, scientists suggest that this matryoshka doll may have a prominent effect on the bacterial hosts.
Life of most organisms on our planet is closely associated with bacterial communities - microbiota that plays a very important role in the health of the host from helping to control digestion to protection of the host from infections. Bryozoa are not an exception. Inside some of these invertebrates the symbiotic bacteria live that, e.g. make larvae not eatable for fish. Yet how
