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.

General Information: Staphylococcus haemolyticus JCSC1435 was isolated from a Japanese inpatient at Juntendo Hospital, Tokyo, in 2000. This strain is a highly resistant strain which has been shown to generate spontaneous antibiotic sensitive mutants. Causes opportunistic infections in humans. Staphylcocci are generally found inhabiting the skin and mucous membranes of mammals and birds. Some members of this genus can be found as human commensals and these are generally believed to have the greatest pathogenic potential in opportunistic infections. Staphylococcus haemolyticus was originally isolated from human skin and traditionally considered to be a nonpathogenic commensal. Recently this organism has been recognized as a pathogen in animals and humans. It is known to be involved in opportunistic infections associated with the implantation of foreign bodies, paticularly in those with compromised immune systems. Resistance to multiple antibiotics has been observed in clinical isolates and it is possible S. haemolyticus could serve a donor or resistance genes to other more virulent staphlococci.
