This is a response to the letter to the editor

Dear editor

Thanks to Dr. Savita V Jadhav and the medical stuff for their interest in our article.1 We would like to clarify the specific comments.

First, concerns about the “CLSI Methodology Guideline Reference Number 19” may be the result of a misunderstanding. In this context, we mentioned that the MIC determination method was recommended by the CLSI guideline rather than why RIF and CLI were selected for testing. Secondly, comments on RIF prescribing should be avoided in diseases other than Mycobacterial diseases are very constructive. At present, our research remains at the laboratory stage; it is necessary to apply in vivo to evaluate the clinical effects as RIF alone is rarely used to treat MRSA. However, no paperwork or guidelines show that RIF can not treat MRSA infection. According to the updated MRSA treatment guidelines from the United Kingdom,2 RIF is recommended in combination with other agents to treat MRSA infections. Our study found that berberine in combination with RIF has an excellent synergistic effect that does not conflict with clinical application. In addition, the synergistic activities are ongoing in vivo and it is our pleasure to improve the clinical practice that expands the RIF indication if the experimental results are satisfactory. Finally, regarding your advice to us to further evaluate other synergistic effects with oxacillin, azithromycin and levofloxacin as well as additive effects with ampicillin and cefazolin, these have already been reported in previous studies.3,4 We believe this is a meaningful proposal and will carry out the in vivo experiments in the near future.
