- Household water treatment systems, such as water filters, might affect the composition of gut microbiota, according to results presented at the ASM Microbe 2019 meeting.
Why this matters
- The authors focused on householders living in a single Wisconsin county to look at water treatment as a predictor of gut microbiome composition.
- 138/466 used some kind of water treatment system or water filter.
- Use of either was linked significantly to education (P=.006) and income (P<.001 level and living in a rural area class="">
- Diversity of gut microbes decreased with water treatment in a rural county (P=.010), as did richness (P=.033).
- Diversity increased with age (P=.008).
- Representation of several genera (Collinsella, Coprobacillus, Coprococcus, Lactobacillus) and other taxa (e.g., class Clostridia) was significantly different with water treatment (P≤.05).
- Adults age 18+ living in Wisconsin and who participated in the 2016 Survey of the Health of Wisconsin and submitted a stool sample.
- DNA of 16s rRNA was used to identify gut microbes.
- Funding: Not cited.
- Results confined to a single US area and presented without peer review at a conference.
