^aCla, clarithromycin; Cli, clindamycin; Ery, erythromycin; Gm, gentamicin; Spc, spectinomycin; Str, streptomycin.

^bND, not done; DD503 is streptomycin resistant because of a chromosomal rpsL mutation.

^cThe mini-Tn7 elements are integrated at the glmS2-associated Tn7 attachment site [20]. MIC values were determined in cells grown in the presence of 1 mM isopropyl-β-D-thiogalactopyranoside.
