Query: NC_002488:2502000 Xylella fastidiosa 9a5c, complete genome

Lineage: Xylella fastidiosa; Xylella; Xanthomonadaceae; Xanthomonadales; Proteobacteria; Bacteria

General Information: This strain was derived from a pathogenic strain (8.1b) isolated in 1992 in France that had come from infected twigs derived from the sweet orange strain Valencia in Brazil in the same year. This organism was first identified in 1993 as the causal agent of citrus variegated chlorosis, a disease that affects varieties of sweet oranges. 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. 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. It does not contain a type III secretion system, but possesses genes for a type II secretion system for export of exoenzymes that degrade the plant cell wall and allow the bacterium to colonize the plant xylem.

Subject: NC_011025:183287 Mycoplasma arthritidis 158L3-1, complete genome

Lineage: Mycoplasma arthritidis; Mycoplasma; Mycoplasmataceae; Mycoplasmatales; Tenericutes; Bacteria

General Information: This organism causes arthritis in both rats and mice. Strains of Mycoplasma arthritidis can be virulent or avirulent depending, in part, on the presence of the MAV1 bacteriophage. This genus currently comprizes more than 120 obligate parasitic species found in the wide spectrum of hosts, including humans, animals, insects and plants. The primary habitats of human and animal mycoplasmas are mucouse membranes of the respiratory and urogenital tracts, eyes, mammary glands and the joints. Infection that proceeds through attachment of the bacteria to the host cell via specialized surface proteins, adhesins, and subsequent invation, results in prolonged intracellular persistence that may cause lethality. Once detected in association with their eukaryotic host tissue, most of mycoplasmas can be cultivated in the absence of a host if their extremely fastidious growth requirements are met.
