First Report of in Bulgaria.

This study aims at the identification and characterization of five actinobacterial strains with presumed belonging to the species isolated from tomato and pepper plants, and establishing the potential role of both plants as natural reservoirs of this phytopathogen. Species identification was performed via MALDI-ToF MS, 16S rDNA sequencing and PCR. The strains were Gram-positive with a coryneform cell shape having yellow/orange-pigmented colonies; positive for catalase and esculin, and starch and casein hydrolysis; oxidase-, urease-, indole- and nitrate-reduction-negative and were strictly aerobic.

Involvement of oxidative stress in localization of bacterial spot infection in pepper plants.

is a major cause of bacterial spot disease in various crops. The present study was focused on the pathosystem pepper ( L.) - 269p (wild strain).

-Specific Bacteriophage BsXeu269p/3 Reduces the Spread of Bacterial Spot Disease in Pepper Plants.

The present study was focused on the pathosystem pepper plants ( L.)-phytopathogenic bacterium (wild strain 269p)-bacteriophage BsXeu269p/3 and the possibility of bacteriophage-mediated biocontrol of the disease. Two new model systems were designed for the monitoring of the effect of the phage treatment on the infectious process in vivo.

Phenotypic and Genotypic Characterization of Newly Isolated -Specific Bacteriophages and Evaluation of Their Biocontrol Potential.

Bacteriophages have greatly engaged the attention of scientists worldwide due to the continuously increasing resistance of phytopathogenic bacteria to commercially used chemical pesticides. However, the knowledge regarding phages is still very insufficient and must be continuously expanded. This paper presents the results of the isolation, characterization, and evaluation of the potential of 11 phage isolates as natural predators of a severe phytopathogenic bacterium-.

Cross-Over Pathogenic Bacteria Detected in Infected Tomatoes ( L.) and Peppers ( L.) in Bulgaria.

The ability of certain human pathogens to adapt to plants without losing their virulence toward people is a major concern today. Thus, the aim of the present work was the investigation of the presence of cross-over pathogenic bacteria in infected tomato and pepper plants. The objects of the study were 21 samples from seven different parts of the plants and three from tomato rhizosphere.
