MedicalResearch.com: What is the background for this study? What are the main findings?  Do you think these findings would be similar with other antibiotics (oral or topical) or with isotretinoin for acne?

Response: We prescribe antibiotics frequently for acne. We certainly know it affects our normal and abnormal bacteria on our skin. But we don’t fully understand how well or not people recover from antibiotics. 

MedicalResearch.com: What should readers take away from your report?

Response: There are variable recovery rates on the bacteria that live on our skin after antibiotics in people. Some bacteria are still altered months after stopping antibiotics. 

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response: We need more studies to understand how our normal bacteria recover from systemic antibiotics.
