Evaluation of Different Formulations on the Viability of Phages for Use in Agriculture.

Bacteriophages have been proposed as biological controllers to protect plants against different bacterial pathogens. In this scenario, one of the main challenges is the low viability of phages in plants and under adverse environmental conditions. This work explores the use of 12 compounds and 14 different formulations to increase the viability of a phage mixture that demonstrated biocontrol capacity against pv.

Characterization of Bacteriophages against pv. with Potential Use as Natural Antimicrobials in Kiwifruit Plants.

pv. (Psa) is the causal agent of a bacterial canker in kiwifruit plants and has caused economic losses worldwide. Currently, the primary strategies to control this pathogen include the use of copper-based compounds and even antibiotics.

Diversification of Driven by the Bacteriophage CHOED.

Bacteriophages are an important factor in bacterial evolution. Some reports suggest that lytic bacteriophages can select for resistant mutant strains with reduced virulence. The present study explores the role of the CHOED bacteriophage in the diversification and virulence of its host .

Virulence reduction in bacteriophage resistant bacteria.

Bacteriophages can influence the abundance, diversity, and evolution of bacterial communities. Several bacteriophages have been reported to add virulence factors to their host and to increase bacterial virulence. However, lytic bacteriophages can also exert a selective pressure allowing the proliferation of strains with reduced virulence.

Natural lysogenization and transduction in Salmonella enterica serovar Choleraesuis by bacteriophage P1.

It has been reported that bacteriophage P1 injects DNA into serovar Choleraesuis without evidence of productive infection. However, we found that P1 generates progeny and is capable of transduction in serovar Choleraesuis. This is not the case with other serovars of Salmonella enterica we tested.
