TLDR
Using a new method for quantitative enumeration, up to 2.5 x IO8 virus particles per millilitre in natural waters indicate that virus infection may be an important factor in the ecological control of planktonic micro-organisms.Abstract:
The concentration of bacteriophages in natural unpolluted waters is in general believed to be low, and they have therefore been considered ecologically unimportant. Using a new method for quantitative enumeration, we have found up to 2.5 x 10(8) virus particles per millilitre in natural waters. These concentrations indicate that virus infection may be an important factor in the ecological control of planktonic micro-organisms, and that viruses might mediate genetic exchange among bacteria in natural aquatic environments.read more

TL;DR: The amplification of g20 products from deep in the cyanobacterium-sparse Chuckchi Sea suggests that this primer set targets bacteriophages other than those infecting cyanobacteria.

Population Dynamics of Chesapeake Bay Virioplankton: Total-Community Analysis by Pulsed-Field Gel Electrophoresis
TL;DR: It is concluded that, based on the dynamic nature of the Chesapeake Bay virioplankton community structure, the clonal diversity of bacterio- and phytoplankon host communities is an important component of the virus community.

TL;DR: The host range of a bacteriophage is the taxonomic diversity of hosts it can successfully infect host range, one of the central traits to understand in phages, is determined by a range of molecular interactions between phage and host throughout the infection cycle.

TL;DR: It is suggested that bacteriophages do not affect the number or activity of bacteria in environments where the density of the host species is below the host cell threshold of about 10(4) CFU/ml.

Rate of bacterial mortality in aquatic environments
TL;DR: Results obtained from river water, estuarine water, and seawater show overall bacterial mortality rates in the range 0.010 to 0.030 h, in good agreement with the range of growth rates measured in the same environments.

TL;DR: Evidence is presented that previously uncharacterized, small eukaryotes that are able to pass even 0.6-micrometer filters may be responsible for a large fraction of the total grazing in coastal waters.
