  • a Also positive for intI2.

  • b NP, not present. IRt is inferred to be absent based on the failure to generate a PCR product with tniA-specific primers.

  • c NS, PCR product was not sequenced.

  • d A plus or a minus sign indicates the presence or absence of a PCR product with primers HS549/HS550.

  • e NA, not applicable. No array recovered.
