Reproductive Morphometric Plasticity in Gregarina polymorpha Infecting Tenebrio molitor Larvae

Journal of Eukaryotic Microbiology, Volume 73, Issue 5, September/October 2026.
ABSTRACT Morphological variability remains one of the principal challenges in the taxonomy and species delimitation of gregarines (Apicomplexa: Gregarinomorphea). In the present study, we investigated morphometric variability in gametocysts and syzygies of Gregarina polymorpha infecting Tenebrio molitor larvae through quantitative morphometric and ...

Molecular Genetics of Hepatozoon canis With a Note on Effect of Parasite on the Complete Blood Count Profile of Canine Hosts

Ecology and Evolution, Volume 16, Issue 8, August 2026.
A total of 654 blood samples were collected from healthy dogs in Punjab and Khyber Pakhtunkhwa provinces in Pakistan and screened for the presence of Hepatozoon canis. Genetic diversity of the detected H. canis DNA, infection‐associated risk factors, and changes in the complete blood count of the host due to parasitic activity were also evaluated.

Post‐LECA Origin and Diversification of an Axonemal Outer Arm Dynein Motor

Cytoskeleton, Volume 83, Issue 7, Page 457-465, July 2026.
ABSTRACT Dyneins were present in the last eukaryotic common ancestor (LECA) and play key roles in eukaryotic biology. Axonemal dyneins form the inner and outer arms that power ciliary beating, and it has long been recognized that outer arms in some organisms contain two different heavy chain motors, whereas those from other species contain a third unit

Molecular characterization of Neospora caninum major antigens NcSAG1 and NcSRS2

Royal Society Open Science
The SAG1-related sequence (SRS) protein family was initially identified in Toxoplasma gondii as glycosyl-phosphatidylinositol-anchored surface antigens.

Discovery of an Atypical Arp2/3 Complex in Malaria Parasites Sheds New Light on Nuclear Actin

Cytoskeleton, Volume 83, Issue 7, Page 479-483, July 2026.
ABSTRACT The Arp2/3 complex is a key actin nucleator essential for cytoskeletal dynamics in eukaryotes. Previously believed absent in apicomplexan parasites, we recently identified an atypical Arp2/3 complex in malaria parasites consisting of five divergent subunits and a putative kinetochore‐associated factor.

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
