  • a See Table 1 for abbreviations for antimicrobials. Isolates were considered resistant to CIP when growth occurred on MH agar containing 0.125 μg of CIP/ml. Antimicrobials shown in parentheses are those to which the isolates may or may not be additionally resistant.

  • b NI, none isolated.

  • c Susc., susceptible.
