Contrary to longstanding assumptions, the human appendix may have a useful role in human health, according to scientists at Duke University School of Medicine in Durham, NC. They suggest it may be a “safe house” for commensal bacteria, providing support for their growth and facilitating reinoculation of the colon when the intestinal tract’s contents are purged following exposure to a pathogen (Bollinger RR et al.
