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.

Dutilhiteiten 2019

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…

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.
