MedicalResearch.com Interview with: Morgan Walker Ph.D. Candidate, UNC-Chapel Hill Chemistry Redinbo Laboratory MedicalResearch.com: What is the background for this study? Where is triclosan commonly found? Response: Triclosan is a commonly found antibacterial compound present in hand soaps, toothpastes, athletic clothes, and children’s toys. A previous study by the Zhang group (corresponding author on this publication) found that antimicrobial compounds including triclosan increased inflammation (similar to that of inflammatory bowel disease (IBD)) and tumor formation in the colon. These effects were observed only in mice with an intact gut microbiome, not in germ-free mice which lack a gut microbiome, suggesting that the gut microbiome is somehow responsible for the toxicity of triclosan to the gut. Our study investigates how gut bacteria promote triclosan toxicity in the gut  (more…)
