Kudoa genomes from contaminated hosts reveal extensive gene order conservation and rapid sequence evolution
Myxozoans are obligate endoparasites that belong to the phylum Cnidaria. Compared to their closest free-living relatives, they have evolved highly simplified body plans and reduced genomes. Kudoa iwat...

Myxozoans are single-celled parasites which are related to jellyfish. They infect and proliferate in the fish's muscles causing no apparent illness, but when the host dies, the muscles liquify, causing something known as "soft flesh" or "milky flesh". 🧪

The Myxozoan Kudoa septempunctata infects the muscles of olive flounder. 🧪
Adult BALB/c mice were fed with spores of K. septempunctata. This 2015 paper concluded that K. septempunctata spores did not affect the gastrointestinal tract of adult mice.

Identifying the parasite sequences is tricky due to missing reference data. Cross-referencing distinct components of the chromatin interaction network (identified by unsupervised clustering) and ribosomal markers provided an initial set of myxozoan scaffolds.
