The influence of bacteriophages on the manifestation of their pathogenic properties by Xanthomonas campestris bacteria

Abstract The use of bacteriophages to control the development different bacterioses, including those caused by bacterium Xanthomonas campestris is one most promising areas in field plant protection. At same time, selection active and determination parameters their remains urgent tasks this direction. phage preparations with low initial concentration particles may not only prevent bacterial disease, but also lead emergence phage-resistant strains. In paper, influence various concentrations on strains possibility latter infecting host analyzed. It was established that treatment suspensions a titer 10 7 -10 8 PFU/ml excluded disease plants inoculated suspension. case decrease bacteriophage, some cases, symptoms began appear, down point after phages 3 PFU/ml, suspension noted all studied cases.
