About the episode
Utilizing samples from Viking baths, scientists from the College of Copenhagen were able to map the genes of one particular of our oldest parasites.
It is the whipworm, which owes its identify to its condition. Insects grow to the size of a matchstick and we grow to be contaminated when we ingest their eggs by ingesting or eating. The an infection, which ranges from gentle and asymptomatic to intense with all varieties of nagging intestinal illnesses, can now be addressed properly. Hundreds of millions of men and women are however contaminated, especially in the poorest nations around the world, and that leads to quite a few health challenges there.
Fossils of the parasite’s sturdy eggs located in feces from 2,500 yrs in the past were applied for the research. That feces once more came from the community baths discovered amongst the remains of a Viking group in Denmark.
The DNA of the eggs has been fully studied and when compared with the DNA of the present-day parasite. All of this has supplied new insights into the fragile relationship in between humans and whipworms. A romance that is not only damaging, since worms can also have a positive impact on our immune process and intestinal flora.
The new awareness can now assist researchers acquire it a action further in predicting and combating resistance and unfold of the parasite.
