The present study on olive tuberculosis commenced by isolating bacteria of the genus Pseudomonas from the soils and necrosis of collected olive trees. A total of 180 samples were used in this study: (100) rhizospheric soil samples: (60) samples at the region of Ain Témouchent and (40) at the region of Sig in western of Algeria. In total, (80) galls were collected (40) at branch level and (40) galls at olive tree leaf (level). The isolates were identified by microbiological (macroscopic and microscopic examination), physiological (growth in the presence of Salt (NaCl), growth at different pH values and growth at different temperatures) and biochemical methods (the LOPAT and Galeries Api 20 NE test to identify species of the Pseudomonas group and conventional biochemical tests to identify the subspecies P. syringae pv. Savastanoi).This allowed to identify 110 isolates of Pseudomonas (60 isolates of P. aeruginosa, 35 isolates of P. fluorescens and 15 isolates of P. syringae pv Savastanoi the causal agent of olive node disease) which are now part of the collection of Pseudomonas bacteria of the laboratory of the Biotechnology Department (USTO-MB). The selection of technological performance isolates useful for our agriculture could solve phytopathological problems and finally constitute a collection of the bacteria preserved.

Viable disseminating units of Pseudomonas syringae pv. tomato (Okabe) Young, Dye and Wilkie and Xanthomonas campestris pv. vesicatoria (Doidge) Dye, the bacterial leaf pathogens of tomato and pepper, respectively, and Alternaria macrospora Zimm, the causal agent of Alternaria blight in cotton, were found to be carried by a wide variety of agents including animals, people, insects, mites, agricultural tools, aircraft, soil particles, and water sources. Of these, specific insects and tools commonly used for crop cultivation were the most heavily contaminated. Soil adhering to agricultural tools or carried by various water sources can also serve as a disseminating agent. It was concluded that nearly all accidental agents passing through the infested field may act as vectors of these pathogens.
