Grouping of Xanthomonas campestris pathovars by SDS-PAGE of proteins

Outer Membrane Proteins and Lipopolysaccharides in Pathovars of Xanthomonas campestris.

Variations in the outer membrane proteins (OMPs) and lipopolysaccharides (LPSs) of 54 isolates belonging to 16 different pathovars of Xanthomonas campestris were characterized. OMP samples prepared by sarcosyl extraction of cell walls and LPS samples prepared by proteinase K treatment of sonicated cells were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis in the presence o...

Characterization of Xanthomonas campestris Pathovars by rRNA Gene Restriction Patterns.

Genomic DNA of 191 strains of the family Pseudomonadaceae, including 187 strains of the genus Xanthomonas, was cleaved by EcoRI endonuclease. After hybridization of Southern transfer blots with 2-acetylamino-fluorene-labelled Escherichia coli 16+23S rRNA probe, 27 different patterns were obtained. The strains are clearly distinguishable at the genus, species, and pathovar levels. The variabilit...

Induction of Hydrolytic Enzymes in Brassica campestris in Response to Pathovars of Xanthomonas campestris.

Inoculation of mature leaves of turnip (Brassica campestris) with the incompatible Xanthomonas campestris pv vitians resulted in the induction of beta-1,3-glucanase and chitinase/lysozyme (CHL) activity. No increase in the basal activity of beta-1,3-glucanase was observed after inoculation of leaves with heat- or rifampicin-killed X. c. vitians, Escherichia coli, or sterile water. Inoculation w...

Identification of electrophoretic proteins pattern of Fusaium verticillioides isolates from maize by SDS-PAGE.

Study on pattern of Neospora caninumtachyzoite proteins by SDS-PAGE and Western blotting in aborted cows

The intracellular parasite Neospora caninumis prevalent in several countries and is increasingly recognized as an important cause of abortion and stillbirth in cattle. For characterizeing the tachyzoite antigens of Neospora caninumin aborted cows, sera were obtained from 116 cows which were aborted in the third semester of the pregnancy period and had antibodies to Neospora caninumin ELISA. To ...
