The interaction between bacteriophages, bacteria and the human host as a tripartite system has recently captured attention. The taxonomic diversity of bacteriophages, as a natural parasite of bacteria
Pseudomonas phage phiPpMK2-1 is a bacteriophage isolated from soil samples collected from the Kansai University campus. The phage was confirmed to infect Pseudomonas putida NBRC 14164.
In this study, bacteriophage which infected the predatory bacterium, Bdellovibrio bacteriovorus, were isolated from sewage and characterised with respect to their infection kinetics.
