Characterization of six bacteriophages of Serratia liquefaciens CP6 isolated from the sugar beet phytosphere
Article Abstract:
Basic morphological, genetic and physiological differences were identified in six phages commonly found in the phytosphere of sugar beet in a study that aimed to improve understanding of how the characteristics of these phages might determine their natural ecology. Fundamental differences were especially noted between phages phiCP6-1 and phiCP6-4. PhiCP6-1 was identified as a temperate phage with an average burst size of 224 virions per infected cell, while phiCP6-4 was found to be virulent and with a burst size remarkably smaller than that of phiCP6-1. The latter was found to be capable of forming a lysogenic association with its host like phiCP6-2, phiCP6-3 and phiCP6-5.

In situ population dynamics of bacterial viruses in a terrestrial environment
Article Abstract:
The in situ population dynamics of three separate phage populations preying on separate bacterial species found on the surface of sugar beet have been studied during a nine-month period. It has been noted that the populations of the three bacteriophages varied and fluctuated temporally during 1996. The phage population that preys on the phytosphere bacterium Serratia liquefaciens CP6 is made up of six distinct DNA phages. Temporal succession was also observed between the two other phage populations.

Seasonal population dynamics and interactions of competing bacteriophages and their host in the rhizosphere
Article Abstract:
Results reveal that both forms of bacteriophage show similar survival in situ although they are physiologically distinct. Data suggest that blooming of the bacteriophage and their increase in the soil, within a sugar beet rhizosphere, is in accordance with the optimal foraging theory as applied to ecological behavior of phages.
