With the exception of CTX (MIC of 8 mg/L), reference strains L. pneumophila sg 1 and L. jordanis showed similar susceptibilities to those of the environmental isolates (Table 5). In the case of P. aeruginosa and S. aureus, DOC showed the highest MIC (>32 mg/L); however, it should be noted that MICs for DOC and MIN were influenced by the type of medium (BYE or MH) (Table 5).
