Abstract
Purpose: Clindamycin is commonly used in the treatment of erythromycin resistant Staphylococcus aureus causing skin and soft tissue infections. In vitro routine tests for clindamycin susceptibility may fail to detect inducible clindamycin resistance due to erm genes resulting in treatment failure, thus necessitating the need to detect such resistance by a simple D test on routine basis. Materials and Method: 200 Staphylococcus aureus isolates were subjected to routine antibiotic susceptibility testing including cefoxitin (30mcg) by Kirby Bauer disc diffusion method. Inducible clindamycin resistance was detected by D test, as per CLSI guidelines on erythromycin resistant isolates. Results: 48 (41.02%) isolates showed inducible clindamycin resistance, 32 (27.35%) showed constitutive resistance while remaining 37 (31.62%) showed MS phenotype. Inducible resistance and constitutive resistance were found to be higher in MRSA as compared to MSSA (32.69%, 26.92% and 14.58%, 4.16% respectively). Conclusion: Study showed that D test should be used as a mandatory method in routine disc diffusion testing to detect induciblernClindamycin resistance.
