We report a novel mutation, Cl 066U in 16S rRNA whichwas selected for resistance to spectinomycin, anantibiotic which inhibits ribosomal translocation. Theminimal inhibitory concentration (MIC) of spectinomycindetermined for this mutant (15 pg/ml) is greaterthan with the wild-type plasmid (5 ig/ml) but lower thanwith the well known C1192U mutation (>80 pg/ml). TheCl 066U mutation also increases the cells sensitivity tofusidic acid, another antibiotic which inhibits translationat the translocation stage, whereas C1192U isunchanged relative to the wild type. We discuss whythe acquisition of resistance to one of these drugs isoften associated with hypersensitivity to the other.
