Brandtodinium nutricula is a dinoflagellate species commonly reported in symbiosis with the marine protist host lineage, Collodaria (Rhizaria). Despite the widespread abundance of this symbiosis throu...

Euglena gracilis is one of biology's outliers. This single-celled protist diverged from plants and animals over a billion years ago, switches effortlessly between photosynthesis and feeding, and carries a genome stitched together from multiple ancient endosymbionts. It controls its genes in ways that break the textbook rules: trans-splicing, a modified DNA base (base J), and heavy reliance on post-transcriptional control rather than classical promoters.

The Retaria are an abundant marine protist lineage that play a substantial role in biogeochemical cycling, primary production, and food web dynamics in open ocean ecosystems. Their impact is, in large...

Viruses infect organisms across the tree of life, but many are not associated with a specific host. Here we present VHAMSTeR (Virus Host Assignment Model using Sequence Transformers and Reading-frames...

Colpodella spp. is a free-living, flagellated protist and predator belonging to the order Colpodellida. It is recognized as the closest genetic relative to the phylum Apicomplexa. Although Colpodella spp. is generally not pathogenic to humans, recent studies have shown that under certain conditions it can act as an opportunistic pathogen, infecting humans and animals. The aim of this article is to present the first report of Colpodella spp. isolation from urine samples of two patients with heart...
