We designed oligonucleotides to differentiate between the seven curren
tly known Capnocytophaga species. The oligonucleotides were labelled n
on-radioactively at the 3' end with digoxigenin. The specificity could
be demonstrated in a dot-blot hybridization assay by using the type s
trains, reference strains, and 37 clinical Capnocytophaga isolates as
well as 11 representative strains of other taxa as a template. The sen
sitivity of the assay was calculated with 10(3) bacteria per dot. (C)
