Abstract: Stereomicroscopic observations using oblique illuminations revealed the presence of two types of movement trails by Xylella fastidiosa strains (A- and G-genotypes) isolated from almond-leaf scorch samples on the surface of PW and PD3 culture media. The A-genotype strains showed curved motility trails, and the G-genotype strains showed straight motility trails. Haloes were found around some G-genotype colonies due to the excretion of unknown factors and (or) compounds, which might be related to bacterial surface motility.
Key words: Xylella fastidiosa, surface motility, slime trail, almond-leaf scorch.
Resume: Des observations par illumination ...
