Primary source abstract: "In this study, the abundances of specific viruses in Chesapeake Bay water samples were monitored, using nucleic acid probes and hybridization analysis. Total virioplankton in a water sample was separated by pulsed-field gel electrophoresis and hybridized with nucleic acid probes specific to either single viral strains or a group of viruses with similar genome sizes. The abundances of specific viruses were inferred from the intensity of the hybridization signal." |

P.3677 right column top paragraph: "In eutrophic estuarine water, bacteria are found at a density of 10^6 cells/ml and viruses with a concentration of 10^7 particles/ml. These concentrations are estimates that vary with the seasons and the geographical location. In addition, these figures refer to physical and not viable entities. A popular model postulates about 10 to 50 different bacterial species and 100 to 300 different phage strains (primary source) in this environment. The higher number of phage species was justified by the fact that each bacterial species may be infected by 10 phage species." |
