^aCentroid is the sequence of the type strain of the species.

^bError type 1, short sequence selected as centroid; error type 2, inaccurate or insufficient entries in the public database (error types 2A and 2B, inaccurate information in the public database; error type 2C, possible sequence errors in type strains); error type 3, heterogeneous sequences of members of a species.

^cClinical isolates have results identical to those of the type strains.
