TABLE 3.

Identifications of the 39 strains of S. mitis, S. pneumoniae, and S. oralis on the basis of the partial gdh sequences^a

Taxonomic species	No. of strains	Best taxon match	Next best taxon match	Identity		Maximum score	Maximum score difference from next best taxon match
				No. of base pairs	%
S. mitis	10	S. mitis	S. pneumoniae	410-419	98.5-100	708-722	18-27
S. mitis	1	S. mitis	S. pseudopneumoniae	410	97	702	0
S. oralisb	11	S. oralis	S. mitis	430-431	99-100	778	36-195

^aData are compiled for strains belonging to the same species. The partial gdh gene sequences are all 431 bp in length.

^bThe gdh sequences of strains SSI 220/202, SK155, and SK610 and type strain CCUG24891 were achieved in our laboratory. The gdh sequences of strains SK100, SK152, SK555, SK394, SK570, SK573, and SK580 were downloaded from M. Kilian's website (www.immi.au.dk/service/download/kilian).
