This failure happens due to inducible clindamycin resistance. The problem is caused by erm genes. This enzyme methylates 23S rRNA on the 50S ribosome → the antibiotic can no longer bind to the target site. | Elmicrobiologist | Facebook

Staphylococcus aureus is a very common bacteria often found growing harmlessly on the skin. Although originally responsive to penicillin, strains soon emerged that were resistant to the antibiotic. When a derivative of penicillin called methicillin was developed to combat these strains, Methicillin-resistant Staphylococcus aureus (MRSA) materialized. And the antibiotic resistance of MRSA-strains continues to improve: some strains of this “superbug” are now resistant to virtually all known treatm
