Influence of infected cell growth state on bacteriophage reactivation levels
Article Abstract:
Pseudomonas aeruginosa can reactivate UV-damaged bacteriophages by dark repair more efficiently when infected during the stationary phase of growth or during starvation. The extent of reactivation also depended on the type of bacteriophage.

Prevalence of broad-host-range lytic bacteriophages of Sphaerotilus natans, Escherichia coli, and Pseudomonas aeruginosa
Article Abstract:
Two bacteriophage collections' abilities to form plaques on multiple bacterial host species were examined. Nine of the 10 phages analyzed were found to be broad-host-range bacteriophages. Findings demonstrated that a multiple-host environment protocol may be more effective for the isolation of bacteriophages by avoiding the selection bias inherent in single-host methods. Transduction was generated by at least two of the broad-host-range bacteriophages.

Characterization of Pseudomonas aeruginosa bacteriophage UNL-1, a bacterial virus with a novel UV-A-inducible DNA damage reactivation phenotype
Article Abstract:
The lytic virus of Pseudomonas aeruginosa, UNL-1, was observed to express a novel inducible DNA damage reactivation activity in UV-A-irradiated P. aeruginosa host cells. The expression of bacteriophage reactivation was quantified in hosts exposed to either UV-C or UV-A radiation. Around 13-fold induction was observed in UV-A-irradiated host cells. When host cells were exposed to sunlight, reactivation of damaged UNL-1 virus increased eightfold. Findings suggest that a combination of host and virus DNA repair processes contributes to replication of aquatic bacterial viruses.
