Type of Drinking water & Gut Microbial Signature

Type of Drinking water Gut Microbial Signature

 News Release, International Society of Microbiota, France – March 21, 2022

The gut microbiota exerts a fundamental role on host physiology, and how extrinsic perturbations influence its composition has been increasingly examined.Yet, the effect of drinking water on gut microbiota is still poorly understood. This research by Dias et al., explored the response of mouse gut bacterial community (fecal and mucosa-adhered) to the ingestion of different types of drinking water.

The experimental cohort was divided according to different water sources into four groups of mice:

  1. Consumed autoclaved tap water
  2. Consumed water collected directly from a drinking water treatment plant
  3. Consumed tap water
  4. Consumed bottled mineral water.

Differences among groups were observed, especially related to control group, which exhibited the smallest intra-group variation, and the largest distance from test groups on the last experimental day.

Clinically important taxa, such as Acinetobacter and Staphylococcus, increased in feces of mice that drank tap water and in mucosa-adhered samples of animals from disinfected and tap water groups.

Furthermore, it is important to note that, statistical analyses showed that both time elapsed between samplings and water type significantly influenced the variation observed in the samples.

In summary, the results revealed that drinking water potentially affects gut microbiota composition. Additionally, the increase of typical drinking water clinically relevant and antibiotic resistance-associated bacteria in gut microbiota is a cause of concern.

The effect of drinking water on the gut microbiota profile will be extensively discussed during Targeting Microbiota 2022.

Don't forget to join us and benefit from the experience of professional speakers like Prof. Nicolas Barnich who will be discussing the "Beneficial Effects of Natural Mineral Waters on Intestinal Inflammation and the Mucosa-Associated Microbiota".
