Abstract
The specificity of previously published oligonucleotide probes war re- evaluated based on the expanded 16S and 23S rRNA databases. Moreover, new genus- and (sub)species-specific 16S rRNA-targeted oligonucleotide probes were designed in a computer-assisted strategy using the PROBE DESIGN tool of the software package ARE. Probes for Pseudomonas stutze ri and for the genera Acidovorax, Comamonas and Hydrogenophaga were ev aluated. Optimal hybridization conditions for the probes have been det ermined. Using these conditions the probes were tested for binding to 16S rRNA of reference cultures. Furthermore, fluorescently labeled der ivatives of these probes were tested for their applicability for whole cell hybridization. These rRNA-targeted probes are the basis for high -resolution, rapid, automated microbial identification.
