Minimal inhibitory concentration (MIC) of antibiotics to Brucella reference strains and marine isolates. MICs of three macrolides, azithromycin, clarithromycin, erythromycin, and the lincosamide, clindamycin, were determined by Etest. Maximum MIC measurable by the Etest is 256 μg/ml for each of the antibiotics. Brucella strains as listed in Table 1. Ba = B. abortus ; Bs = B. suis; Bm = B. melitensis; Bc = B. canis; Bn = B. neotomae; Bo = B. ovis; numbers following species designate biovar.
