07 Jul 2020 --- Microbiome-based diagnostics and therapeutics must take the ethnicity of the individual into account, warn researchers from APC Microbiome Ireland. Their study revealed that Irish Travellers – an ethnic minority who have long lived on the fringes of Irish society – have a gut microbiome “strikingly” different to that of the non-Traveller settled community. The researchers flag that this investigation could have major implications on everything from the design of infant formula to the outlook for personalized nutrition.
