a
Discrepancy resolved by repeat microarray test.

Discrepancy resolved by PCR.
c
Discrepancy resolved by sequencing.
d
The designations SHV-2 and SHV-5 indicate the bla genes containing the G238S mutation and the G238S and E240K mutations, respectively. KPC and CTX-M-1 represent the family of bla genes. TEM-1 and SHV-1 indicate no mutations found relative to these sequences for the sites assayed by the microarray. ESBL, extended spectrum β-lactamase; NE, not evaluable; ND, test not done.
