A kinetic model for Xylella fastidiosa adhesion, biofilm formation, and virulence
Xylella fastidiosa is the causal agent of citrus variegated chlorosis and Pierce's disease which are the major threat to the citrus and wine industries. The most accepted hypothesis for Xf diseases...
A nested-PCR assay for detection of Xylella fastidiosa in citrus plants and sharpshooter leafhoppers
Detection of Xylella fastidiosa in citrus plants and insect vectors. Chelex 100 resin matrix was successfully standardized allowing a fast DNA extraction of X. fastidiosa. An amplicon of 500 bp wa...
Assessment of four different detergents used to extract membrane proteins from Xylella fastidiosa by two-dimensional electrophoresis
Four different detergents, ASB 14, SB 3-10, CHAPS and Triton X100, were utilized to determine the optimal detergent for the solubilization of membrane proteins from the phytopathogenic bacterium Xy...
Bacterial variations on the methionine salvage pathway
The thiomethyl group of S-adenosylmethionine is often recycled as methionine from methylthioadenosine. The corresponding pathway has been unravelled in Bacillus subtilis. However methylthioadenosin...
Biology of Zagella delicata (Hymenoptera : Trichogrammatidae), an egg parasitoid of the sharpshooter Tapajosa rubromarginata (Hemiptera : Clypeorrhyncha : Clcadellidae) in Argentina
Research on biological control of glassy-winged sharpshooter (GWSS) Homalodisca coagulata (Say) started in the 1990s. This sharpshooter, vector of Pierce's disease bacteria Xylella fastidiosa Wells...
Cell-cell signaling controls Xylella fastidiosa interactions with both insects and plants
Xylella fastidiosa, which causes Pierce's disease of grapevine and other important plant diseases, is a xylem-limited bacterium that depends on insect vectors for transmission. Although many studie...
Colony aggregation and biofilm formation in xylem chemistry-based media for Xylella fastidiosa
Two chemically defined media based on xylem fluid chemistry were developed for Xylella fastidiosa. These media were tested and compared to chemically defined media XDM2, XDM4 and XF-26. New media w...
Comparative dispersal of Homalodisca coagulata and Homalodisca liturata (Homoptera : Cicadellidae)
California's viticulture and ornamental industries have suffered significant losses since the introduction of Homalodisca coagulata (Say), an important vector of the Pierce's disease bacterium. A b...
Comparative genomics of two Leptospira interrogans serovars reveals novel insights into physiology and pathogenesis
Leptospira species colonize a significant proportion of rodent populations worldwide and produce life-threatening infections in accidental hosts, including humans. Complete genome sequencing of Lep...
Complete sequence and evolutionary genomic analysis of the Pseudomonas aeruginosa transposable bacteriophage D3112
Bacteriophage D3112 represents one of two distinct groups of transposable phage found in the clinically relevant, opportunistic pathogen Pseudomonas aeruginosa. To further our understanding of tran...
DNA microarray-based genome comparison of a pathogenic and a nonpathogenic strain of Xylella fastidiosa delineates genes important for bacterial virulence
Xylella fastidiosa is a phytopathogenic bacterium that causes serious diseases in a wide range of economically important crops. Despite extensive comparative analyses of genome sequences of Xylella...
