Sheep may not be an important zoonotic reservoir for Cryptosporidium and Giardia parasites

, 2005
Little is known of the prevalence of Cryptosporidium and Giardia parasites in sheep and the genotypes that they harbor, although potentially sheep may contribute significantly to contamination of watersheds.

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 ...

Rhomboid-like proteins in Apicomplexa: phylogeny and nomenclature

, 2005
Rhomboids form a family of polytopic intramembrane serine proteases. In Toxoplasma gondii, an essential activity called microneme protein protease 1 (MPP1) cleaves secreted adhesive proteins within their transmembrane domains, at a site conserved in ...

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)

An Overview of Peripheral Blood Mononuclear Cells as a Model for Immunological Research of Toxoplasma gondii and Other Apicomplexan Parasites

Frontiers in Cellular and Infection Microbiology, 2019
In biology, models are experimental systems meant to recreate aspects of diseases or human tissue with the goal of generating inferences and approximations that can contribute to the resolution of specific biological problems.

Intestinal Parasite Community Dynamics in the Critically Endangered Chinese Alligator (Alligator sinensis): Multifactorial Insights From 18S rRNA Amplicon Sequencing

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Our results firstly demonstrate the structure of parasite communities in A. sinensis and clarify how they are shaped by interacting ecological and management factors, providing critical baseline data for future research. ABSTRACT The intestinal parasite communities of vertebrates are shaped by complex interactions among biological, environmental, and ...

Assessment of Preservation and Extraction Methods for Environmental DNA in Sediments

Environmental DNA, Volume 8, Issue 3, May–June 2026.
We assessed how different preservation methods (freezing, room temperature, silica gel, Longmire buffer) affect eDNA metabarcoding results for bacterial, fungal, microeukaryotic, and metazoan communities in marine and freshwater sediments. Results demonstrate taxonomic‐ and habitat‐specific responses to preservation methods, providing evidence‐based ...

From Nest Box to Neighborhood: Patterns of Island Biodiversity Characterized Through eDNA From Little Blue Penguin (Eudyptula minor) Nest Boxes

Environmental DNA, Volume 8, Issue 3, May–June 2026.
There are many environmental DNA (eDNA) sources within and around a seabird nest. These DNA traces from soil, plant material, feathers, feces, and other nest components enable detection of a wide range of taxa, including plants, fungi, insects, arachnids, mollusks, reptiles, and other vertebrates. Here, we used DNA from nest box feces to obtain signals
