Diet has a strong effect on the genes that can move between bacterial communities, reveals a study published in Nature.
After more than 8 years of research among populations in Fiji, scientist Ilana Brito also found a prevalence of genes within bacteria found in both people and the environment that were resistant to antibiotics. The finding is particularly surprising because Fijians have never been exposed to some of the powerful antibiotics that are frequently used in Western societies.
The presence of these antibiotic-resistant genes couldn’t be definitively explained, but suggest that such genetic dynamism should be a central consideration when studying microbiomes.
