Developing a detailed understanding of how all known forms of life are related to one
another in the tree of life has been a major preoccupation of biology since the idea of tree …

Awareness of the roles that host‐associated microbes play in host biology has escalated in
recent years. However, microbiome studies have focused essentially on bacteria, and …

The last century has witnessed an increasing rate of new disease emergence across the
world leading to permanent loss of biodiversity. Perkinsea is a microeukaryotic parasitic …

Southern Ocean ecosystems are globally important and vulnerable to global drivers of
change, yet they remain challenging to study. Fish and squid make up a significant portion of …

Abstract Background In Norway, x-cell parasites associated with disease in farmed
salmonids have been known as a rare phenomenon for two decades. These parasites …

Perkinsea constitutes a lineage within the Alveolata eukaryotic superphylum, mainly
composed of parasitic organisms. Some described species represent significant ecological …

Perkinsea is a phylogenetic group of protists that includes parasites of distantly related
hosts. However, its diversity is still mainly composed of environmental sequences, mostly …

Protists play a fundamental role in all ecosystems, but we are still far from estimating the total
diversity of many lineages, in particular in highly diverse environments, such as freshwater …

Studies on freshwater Perkinsea are scarce compared to their marine counterparts; they are
therefore not well ecologically characterized. In this study, we investigated the diversity …

The phylum Perkinsozoa is known as an exclusively parasitic group within alveolates and is
widely distributed in various aquatic environments from marine to freshwater environments …
