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

Blue-Green Catastrophe: remote sensing of mass viral lysis of cyanobacteria
TL;DR: The blue-green catastrophe: remote sensing of mass viral lysis of cyanobacteria and the MERIS potential for inland water quality monitoring and the influence of phytoplankton pigment composition on remote sensing are described.

Genome sequence of the Nocardia bacteriophage NBR1.
TL;DR: A novel bacteriophage (NBR1) that is lytic for Nocardia otitidiscaviarum and N. brasiliensis is characterized and appears to have a structurally more complex tail than previously reported Siphoviridae phages.

Functional Metagenomics: Tools and Applications
TL;DR: This chapter discusses some of the efforts to improve the quality and availability of metagenomic libraries through the production of a series of meetagenomic cosmid libraries from diverse Canadian soils.

In Vitro Structural and Functional Characterization of the Small Heat Shock Proteins (sHSP) of the Cyanophage S-ShM2 and Its Host, Synechococcus sp. WH7803.
TL;DR: In vitro results portray the phage HspSP-ShM2 as a classical sHSP and suggest that it may be functional at the in vivo level while behaving differently than its host amphitropic sH SP.

Minimum bacterial density for bacteriophage replication: implications for significance of bacteriophages in natural ecosystems.
B A Wiggins,M Alexander +1 more
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.

Do bacteria-sized marine eukaryotes consume significant bacterial production?
Jed A. Fuhrman,George B. McManus +1 more
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.
