'Ancient spaghetti' in dog hearts reveals surprising origins of heartworm Understanding heartworm evolution can assist keeping treatments for dogs effective and safe. University of Sydney research points the way to a new paradigm of heartworm evolution.

Check out @sydney.edu.au's latest news article about our global heartworm genomics paper: www.sydney.edu.au/news-opinion... 🌏🪱🐺

And if anyone has any heartworms from under-sampled regions (particularly Asia, South America & Africa), do reach out 👀

(5/5) From hunting down worms for me (which is not an easy task), to helping with analyses and interpretation, big thank you to everyone involved!
@janslapeta.bsky.social @stephenrdoyle.bsky.social @simonh0.bsky.social + many more!

(4/5) Central American and European heartworms were genetically similar, suggesting a modern dispersal with domesticated dogs after European colonisation 🐶

(3/5) Where did Australian heartworms come from? 🇦🇺
Our study found Asian ancestry in Australian heartworms, raising the possibility that they arrived in Australia with dingoes thousands of years ago. However, a post-colonial introduction to the country can't be ruled out just yet.

(2/5) Heartworm populations are genetically distinct on each continent.
This has important implications for how we monitor emerging drug resistance in this parasite. What works in one county may not necessarily work in another.

(1/5) For years, we thought heartworms spread around the world through recent human-mediated movement of domesticated dogs.
Our latest study tells a different story: ancient canid hosts shaped their global distribution over tens of thousands of years, spreading them far earlier than we realised 🐺

Population genomics reveals an ancient origin of heartworms in canids - Communications Biology Genomic analyses of heartworms from multiple continents suggest a deeper evolutionary origin in canids than previously recognised, with evidence of both ancient dispersal events and more recent introd...

Researchers recover a woolly rhino genome from inside a frozen wolf's stomach The work marks the first time an Ice Age animal’s complete genome has been recovered from tissue preserved inside another ancient animal.

Paleogenomics Reveals a Loss of Bovine Lineages in Mid-latitude Asia Over the Last 200,000 Years Abstract. Bovines have a complex yet poorly understood evolutionary history that is characterized by admixture and diversity loss during the Late Pleistoce

@alexgilardet.bsky.social et al. recovered ancient DNA from bovine bones in the Denisova cave to characterize Pleistocene bovine diversity, identifying the Altai Mountains as a hotspot for bovine diversity.
