rrs sequence comparison (nt 38 to 492) of reference sequences of C. canimorsus (ATCC 35979 T, AY643075), C. cynodegmi (ATCC49044 T, AY643076), and a number of Capnocytophaga species strains used in the present study. Nucleotides differing from the reference sequence are shown. A dot indicates identity to the sequence of C. canimorsus, and a dash indicates a deletion. Sequences AY643077 (C. canimorsus 24231 clone 1), AY643078 (C. canimorsus 24231 clone 4), and AF426105 (an uncultivable Capnocytophaga species strain from cat) (marked with asterisks) are shown for comparison. Strain LUMC-DogNido1 (marked with a double asterisk) has 27 additional nucleotide changes from the sequence of the reference strain ATCC 35979, which are not shown in the figure. Nucleotide positions are according to the sequence of accession number AY643075.
