Query: NC_010513:2452811 Xylella fastidiosa M12 chromosome, complete genome

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

General Information: Causal agent of citrus variegated chlorosis. 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. 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. 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. The cell produces an exopolysaccharide that is similar to the xanthan gum produced by Xanthomonas campestris pv. campestris.

Subject: NC_010611:3879190 Acinetobacter baumannii ACICU, complete genome

Lineage: Acinetobacter baumannii; Acinetobacter; Moraxellaceae; Pseudomonadales; Proteobacteria; Bacteria

General Information: Acinetobacter baumannii strain ACICU (also called H34) was isolated from an outbreak in an intensive care unit in Rome, Italy. This bacterium is commonly isolated from the hospital environment and hospitalized patients. It is an aquatic organism, and is often cultured from liquid medical samples such as respiratory secretions, wounds, and urine. Acinetobacter also colonizes irrigating solutions and intravenous solutions. Although it has low virulence, it is capable of causing infection. Most isolates recovered from patients represent colonization rather than infection. When infections do occur, they usually occur in the blood, or in organs with a high fluid content, such as the lungs or urinary tract.Infections by this organism are becoming increasingly problematic due to the high number of resistance genes found in clinical isolates. Some strains are now resistant to all known antibiotics. Most of these genes appear to have been transferred horizontally from other organisms.
