Journal of Eukaryotic Microbiology

🔬Few ciliate structures are as curious as the peritrich stalk. Chuanqi Jiang and colleagues used genomics, biochemistry, mass spectrometry, and immunomicroscopy to decode it, winning the 2025 William Trager Award in @jeukmicro.bsky.social 🔗 https://bit.ly/4zb1mfa

Call for Papers! This Special Issue aims to showcase cutting-edge research presented at the Protistology Open meeting in Prague, as well as high-quality articles closely related to the scientific themes of the meeting. #protistsonsky

🎉Congratulations to Anders Alfjorden and colleagues, winners of the @jeukmicro.bsky.social 2024 William Trager Award! Using molecular, microscopic, and histological methods, they identify three new gregarines linked to pearl mussel mass mortality in Sweden. Find out more: https://bit.ly/4jaaa0d
