These findings emphasize the close interconnections between evolution of bacteriophages and evolution of their hosts.
Also, the presence of bacteriophages in drinking water and subsequently in natural biofilms may not predict the presence of pathogenic viruses.
Phage therapy revisited : the population biology of a bacterial infection and its treatment with bacteriophage and antibiotics.
They contrast it with the planktic lifestyle and suggest that it offers protection from both bacteriophage and predatory amoebae.
Neither was it the result of bacteriophage activity.
Biological and physical simplicity relative to other viral systems have made the bacteriophages an attractive model system in biophysical virology.
Furthermore, both methods enabled us also to detect ' normal ' genetic variations by acquisition of plasmids and bacteriophages.
The molecular weights of the linearized plasmids (see below) and the restriction fragments were determined by comparison with the size of the bacteriophage l molecular-size ladder.
