XYLELLA FASTIDIOSA
| Class: | Gamma Proteobacteria |
| Genus: | Xylella |
| Species: | Xylella fastidiosa |
| Description: | This organism was first identified in 1993 as the causal agent of citrus variegated chlorosis, a disease that affects varieties of sweet oranges. This disease was first noticed in Brazil in 1987, and it greatly affects commercial orchards resulting in crop devastation worldwide. Other strains of this species cause a range of diseases in mulberry, pear, almond, elm, sycamore, oak, maple, pecan and coffee which collectively result in multimillion dollar devastation of economically important plants. |

| Pathogenicity: | Causes phoney peach disease in the southern United States, bacterial leaf scorch, oleander leaf scorch, and Pierce's disease (in grapevines), and citrus variegated chlorosis disease (CVC) in Brazil.In Europe it has attacked olive trees in the Salento area of Southern Italy causing the olive quick decline syndrome(OQDS).The bacteria are transmitted from the gut of the insect vector (sharpshooter leafhopper) to the plant xylem (water conducting system) when the insect feeds. Xylella fastidiosa is similar to Xanthomonas campestris pv. campestris in that it produces a wide variety of pathogenic factors for colonization in a host-specific manner including a large number of fimbrial and afimbrial adhesins for attachment. |
