一般认为天然未污染水域中噬菌体的浓度较低1,2，因此它们被认为在生态上不重要3。使用新的定量计数方法，我们在天然水中发现了每毫升高达 2.5 x IO8 病毒颗粒。这些浓度表明病毒感染可能是浮游微生物生态控制的重要因素，并且病毒可能介导自然水生环境中细菌之间的遗传交换。
THE concentration of bacteriophages in natural unpolluted waters is in general believed to be low1,2, and they have therefore been considered ecologically unimportant3. Using a new method for quantitative enumeration, we have found up to 2.5 x IO8virus 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.
