Mitochondrial Genomes of Klossia Species: The First Complete Extrachromosomal Sequence Data From Parasites in the Monoxenous Apicomplexan Family Adeleidae Mesnil, 1903 (Apicomplexa: Adeleorina)

Journal of Eukaryotic Microbiology, Volume 73, Issue 4, July/August 2026.
ABSTRACT Complete mitochondrial genomes were sequenced and annotated from three Klossia species (Apicomplexa; Adeleorina) infecting snails in North America and Europe. Mitochondrial genomes of K. helicina (type species—NC_058857.1; 6728 bp), K. razorbacki (NC_058856.1; 6775 bp), and K.

Nucleomorph phylogenomics suggests a deep and ancient origin of cryptophyte plastids within Rhodophyta

New Phytologist, Volume 250, Issue 5, Page 3103-3113, June 2026.
Summary The evolutionary origin of red algae‐derived complex plastids remains obscure. Cryptophyta, one of four eukaryotic lineages harboring these plastids, still contains nucleomorphs, which are highly reduced remnants of red algal nuclei. The genes present on nucleomorph genomes can be used for phylogenomic reconstruction in order to unravel the ...

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, Volume 600, Issue 10, Page 1491-1518, May 2026.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Molecular epidemiology of Babesia microti in southern Zhejiang: an integrated survey of humans, rodent reservoirs, and tick vectors (2020–2023)

Frontiers in Microbiology
BackgroundBabesia, an intraerythrocytic protozoan, is globally distributed and poses a significant public health burden. In China, human babesiosis is mainly caused by Babesia microti, and the Zhejiang Province is endemic.

GCN5a is a telomeric lysine acetyltransferase whose loss primes Toxoplasma gondii for latency

mSphere
Toxoplasma gondii is a protozoan parasite that causes persistent infection in warm-blooded vertebrates by undergoing differentiation from a replicative stage (tachyzoites) to a latent encysted stage (bradyzoites).

Simultaneous Ribosome Profiling of Human Host Cells Infected with Toxoplasma gondii

mSphere, 2019
Toxoplasma gondii is a ubiquitous obligate intracellular parasite that infects the nucleated cells of warm-blooded animals. From within the parasitophorous vacuole in which they reside, Toxoplasma tachyzoites secrete an arsenal of effector proteins that ...

First Detection of Cytauxzoon spp. DNA in Questing Ixodes ricinus Ticks

Microorganisms
Feline cytauxzoonosis is an emerging tick-borne disease in Europe. While infections have been reported in different European countries, the tick vector remains unknown. This study investigated 665 ticks collected in 2019 (n = 160), 2022 (n = 7), and 2024

A myzozoan-specific protein is an essential membrane-anchoring component of the succinate dehydrogenase complex in Toxoplasma parasites

Open Biology
Succinate dehydrogenase (SDH) is a protein complex that functions in the tricarboxylic acid cycle and the electron transport chain of mitochondria. In most eukaryotes, SDH is highly conserved and comprises the following four subunits: SdhA and SdhB form ...
