FISH signals are enhanced by microwave pulses applied during the DNA-DNA hybridization process.

Internal contamination of the implants was evaluated with the checkerboard DNA-DNA hybridization method.

This distinction was confirmed by DNA-DNA hybridization and phenotypic tests.

It can be differentiated from these species by using phenotypic characteristics, phylogenetic analysis and DNA-DNA hybridization results.

Results: DNA-DNA hybridization was sensitive enough to detect and quantify the microorganism from the internal parts of the implants.

These results suggest that quantitative microarray hybridization could be an alternative to conventional DNA-DNA hybridization for measuring chromosome relatedness among bacterial species.

DNA-DNA hybridization experiments revealed the presence of three distinct genomospecies and thus confirmed phenotypic differences as revealed by means of extensive biochemical characterization.

DNA-DNA hybridization studies revealed a mean hybridization level of 89% between the donkey isolate from California and the donkey isolate from Kentucky.

Subgingival plaque samples were taken at each visit and analyzed using the checkerboard DNA-DNA hybridization technique for the presence and levels of 40 subgingival species.

The results of DNA-DNA hybridization and the polyphasic data confirmed that strain mano18T can be considered to represent a novel taxon in the genus Stappia.

Digital DNA-DNA hybridization values between the aforementioned studied strains were well below the 70% threshold for assigning prokaryotic strains to a novel species.

On the other hand, the mean DNA-DNA hybridization level from the donkey isolates with DNA from a strain of T. equigenitalis was 23%.

The DNA-DNA hybridization experiment showed that there was less than 40 % relatedness between strain CBA1101(T) and the reference species in the genus Halococcus.
