Use of ribotyping and random amplified polymorphic DNA to differentiate isolates of Burkholderia andropogonis.
OBJECTIVE
The aim of this study was to determine the genetic diversity among isolates of Burkholderia andropogonis from various host plant species and geographic locations.


RESULTS
Both random amplified polymorphic DNA (RAPD) and ribotyping analyses were used to assess the diversity of B. andropogonis isolates and compare these results with pathogenicity assays carried out on a number of common hosts of the organism.


CONCLUSIONS
Both RAPD and ribotyping analyses revealed a high level of genetic diversity between isolates of B. andropogonis. Both methods demonstrated a similar clustering of isolates. However, there was no strict correlation between the genetic diversity revealed and the original host, geographic location or pathogenicity of the isolates.


CONCLUSIONS
This is the first report on the genetic diversity of isolates of B. andropogonis. The great degree of diversity revealed in this study contrasts with the lack of phenotypic diversity within this species.
