The aim of this work was to study the antimicrobial activity of essential oils obtained from Thymus vulgaris (thyme) and Origanum vulgare (oregano) on phytopathogenic @entity3437 species isolated from @entity1460 . Strains with characteristics of @entity3437 were isolated from leaves of @entity1460 plants with @entity1109 . Ten of these could be identified in Group Ia of LOPAT as @entity3437 . Six of these were confirmed as @entity3437 using 16S rRNA, indicating the presence of these phytopathogenic bacteria in east and central Argentina. All the phytopathogenic bacteria were re-isolated and identified from the infected plants. MIC values for thyme were 11.5 and 5.7  mg  ml(-1) on @entity3437 strains, while oregano showed variability in the inhibitory activity. Both essential oils inhibited all @entity3437 strains, with better inhibitory activity than the antibiotic @entity3639 . The oils were not bactericidal for all pseudomonads. Both oils contained high @entity7654 (29.5% and 19.7%, respectively) and low @entity4745 (1.5%). Natural products obtained from aromatic plants represent potential sources of molecules with biological activity that could be used as new alternatives for the treatment of phytopathogenic bacteria infections.
