General antimicrobial susceptibility patterns for the most common Nocardia species

Common antimicrobial susceptibility patterns for the most common Nocardia species are outlined in the table; species are labeled as susceptible if >80% of isolates tested were susceptible and as resistant if >80% of isolates tested were resistant. Such data may be of use when therapy is commenced before antimicrobial susceptibility results are available. The table summarizes data extracted from four studies.^[1-3] The four studies included are not directly comparable because of differences in the number of isolates and species included, antibiotics tested, and the methods of susceptibility testing used. Moxifloxacin was included in only one study; in this report, 81% of 36 N. farcinica isolates were susceptible to moxifloxacin.^[2]
