a
Unless indicated otherwise, these changes are seen only in GenBank entries included in this table.
b
Standard sequence for the dfrA12 and orfF cassettes.
c
Sequence is only available to position 125 of the aadA2 cassette.
d
Standard sequence for the complete dfrA12-orfF-aadA2 array.
e
The aadA8b hybrid cassette is identical to the aadA2 cassette in AF284063 to position 602 and to the standard aadA1 cassette in X12870 from positions 647 to 856.
f
In the 59-base element.
g
This change disrupts the dfrA12 reading frame, and there are likely errors elsewhere in this sequence (10).
h
Found in the prototype aadA2 sequence in X68227.
