Figure 1 :Disc diffusion test for inducible clindamycin resistance (a) Erythromycin resistant and clindamycin sensitive Staphylococcal isolate with circular zone of inhibition around clindamycin suggestive of MS phenotype. (b) Erythromycin resistant and clindamycin sensitive Staphylococcal isolate giving D shaped zone of inhibition around clindamycin with flattening towards erythromycin disc suggestive of inducible MLSB phenotype. (c) Staphylococcal isolate resistant to both erythromycin and clindamycin suggestive of constitutive MLSB phenotype
