Combination of Chromogenic Differential Medium and estA-Specific PCR for Isolation and Detection of Phytopathogenic Xanthomonas spp.
A xanthomonad differential medium (designated Xan-D medium) was developed, on which streaks and colonies of xanthomonads, including 13 species of the genus Xanthomonas, turned wet-shining yellow-gr...
Confirmation of Xylella fastidiosa infecting grapes Vitis vinifera in Costa Rica
In 2003, symptoms of Pierce Disease (PD) were observed in two vineyards established in two different localities in San Jose province (Santa Ana and La Uruca) and in La Garita, Alajuela province. Tw...

ISOLATION AND GROWTH OF STRAINS OF XYLELLA-FASTIDIOSA FROM INFECTED GRAPEVINES ON NUTRIENT AGAR MEDIA
Two grape strains (FC and C) of the causal organism of Pierce’s disease (PD) of grapevine, Xylella fastidiosa, were isolated from infected grape petioles onto PD3 medium, nutrient agar (NA), and NA...
Isolation and pathogenicity of Xylella fastidiosa associated to the olive quick decline syndrome in southern Italy
In autumn 2013, the presence of Xylella fastidiosa, a xylem-limited Gram-negative bacterium, was detected in olive stands of an area of the Ionian coast of the Salento peninsula (Apulia, southern I...
Isolation and pathogenicity of Xylella fastidiosa from grapevine and almond in Iran
Symptoms similar to those of Pierce's disease (PD) of grapevine and leaf scorch of almond were observed in vineyards and almond orchards in several provinces of Iran. Grafting of scions from sympto...
ISOLATION AND PRELIMINARY CHARACTERIZATION OF EXTRACELLULAR PROTEASES PRODUCED BY STRAINS OF XYLELLA-FASTIDIOSA FROM GRAPEVINES
Virulent and weakly virulent grape strains of Xylella fastidiosa grew well on PD3 amended with gelatin and produced zones of hydrolysis on this medium, indicating the presence of proteolytic activi...
ISOLATION, CULTIVATION, AND PATHOGENICITY OF XYLELLA-FASTIDIOSA, THE CAUSAL BACTERIUM OF PEAR LEAF SCORCH DISEASE IN TAIWAN
Leaf scorch symptoms occurred in 12-20.6% of the pear trees (Pyrus pyrifolia) in the low-altitude areas of central Taiwan in 1990. Symptoms appeared on leaves in early July and stayed until the lea...
ISOLATION OF A XYLELLA FASTIDIOSA STRAIN INFECTING OLIVE AND OLEANDER IN APULIA, ITALY
The isolation in pure culture of the Xylella fastidiosa strain associated with the quick decline syndrome of olive, recently observed in Apulia (Salento peninsula, southern Italy) was attempted fro...
Multilocus sequence typing of Xylella fastidiosa isolated from olive affected by "olive quick decline syndrome" in Italy
The recent finding of Xylella fastidiosa (Xf) in olive trees in southern Italy, the scanty molecular information on this bacterium and its association with the olive quick decline syndrome (OQDS) p...
The complete nucleotide sequence and environmental distribution of the cryptic, conjugative, broad-host-range plasmid pIPO2 isolated from bacteria of the wheat rhizosphere
Plasmid pIPO2 is a cryptic, conjugative, broad-host-range plasmid isolated from the wheat rhizosphere. it efficiently self-transfers between alpha, beta and gamma Proteobacteria and has a mobilizin...
