Welcome

This is the website of the Dutilh Family Foundation

The Dutilh family originates from Aquitaine, the French Region located in the South West of the country, in particular from places like Bearn and Orthez. Until to date this is the region where most Dutilh’s are living.

The Dutch Dutilh family descends from Clairac, the city which its ancestors left in around 1700. At present around ninety descendants live around the world, but most of them still live in The Netherlands, with a large number in both Rotterdam and Amsterdam.

In 1962 the Dutch family established the Dutilh Family Foundation, with three main objectives:

  1. Maintain and support the interaction between members of the family
  2. Stimulate collection and preservation of family heritage
  3. Create a better understanding of the family history

This website is one of the tools to achieve those objectives.

For an anxious moment, it was uncertain whether a Dutilhiteiten volume 51 would ever see the light, given that Editor in Chief Chris presented his final masterpiece in 2018. But keep calm! The board has ensured that a new volume sees the light. Dutilhiteiten carries on…

Dutilhiteiten 2018

On January 1st 2018 the 50th edition of the family-magazine Dutilhiteiten was issued. This volume contains among others a report on the family-gathering in Clairac, held in July 2017.

Bas Dutilh co-author of article “The human gut microbiome and health inequities”

Bas Dutilh has contributed to an article about the influence of microbes such as bacteria, fungi, and viruses that live in the human digestive tract on health inequities. The article was published in the Proceedings of the National Academy of Sciences of the USA (PNAS) on June 22, 2021 (https://doi.org/10.1073/pnas.2017947118).

Individuals who are minoritized as a result of race, sexual identity, gender, or socioeconomic status experience a higher prevalence of many diseases. Understanding the biological processes that cause and maintain these socially driven health inequities is essential for addressing them. Our intestinal flora, also known as the human gut microbiome is strongly shaped by host environmental factors and affects host metabolic, immune, and neuroendocrine functions, making it an important pathway by which differences in experiences caused by social, political, and economic forces could contribute to health inequities. At the same time, most studies that investigate the gut microbiome focus on majority populations, while few include the effects of the microbiome on health and disease in minorities. The authors argue that accounting for host-gut microbe interactions will improve understanding and management of health inequities, and that health policy must begin to consider the microbiome as an important pathway linking environments to population health.

Renske Dutilh zwemt 22 km marathon van Stavoren naar Medemblik

Op zaterdag 17 augustus 2019 klonk om 9.00 uur in Stavoren het startschot voor de 50ste IJsselmeer Zwemmarathon Stavoren-Medemblik. 27 zwemmers waagden zich aan de 22 kilometer lange oversteek van Stavoren naar Medemblik. Bekende deelnemers waren Maarten van der Weijden en Kees Bobeldijk. De jongste deelnemer was Renske Dutilh uit Amsterdam. Renske zwemt al vanaf haar 6e jaar en is direct met openwater wedstrijden begonnen. Twee jaar geleden heeft zij haar eerste 10 km gezwommen, wat ze in 2018 heeft herhaald. Het leek haar leuk om dit jaar “iets verder” te gaan.

Bas Dutilh finds human microbiome virus in one-third of all countries

In 2014, Bas Dutilh discovered crAssphage, a new virus that infects bacteria associated to the human intestine, just by analysing “big data”. Although the virus had never been seen before, crAssphage was present in well over 50% of almost one thousand datasets from human faecal samples. As a follow-up of that article, he has now convinced more than 100 scientists worldwide to look for crAssphage in sewage and human faecal samples from their country. Bas is senior author of the resulting publication in Nature Microbiology that describes how they found the virus in one-third of the countries of the world. This new research also suggests why crAssphage is so widespread: the team showed that crAssphage has been with us since the dawn of humankind and has spread with us as we colonised the globe. CrAssphage seems to have no effect on human health or disease, so without impeding our fitness the virus could survive in the human lineage without being selected out.
