Extracellular Vesicles in Arthropods: Biogenesis, Functions, Isolation Methods and Applications

Journal of Extracellular Vesicles, Volume 14, Issue 9, September 2025.
ABSTRACT Extracellular vesicles (EVs) are membrane‐bound nanoparticles secreted by cells that are involved in multiple forms of intercellular communication and show promising potential for biotechnological applications. Arthropod‐derived EV research remains relatively fragmented in contrast to the extensively studied mammalian EV field. In this review,

Is Zebrafish a Good Model for the Alpha‐Gal Syndrome?

The FASEB Journal, Volume 39, Issue 9, 15 May 2025.
ABSTRACT The alpha‐Gal syndrome (AGS) is an underdiagnosed tick‐borne allergy characterized by both immediate and delayed IgE‐mediated anaphylactic reactions to the galactose‐alpha‐1,3‐galactose (alpha‐Gal) epitope. Common manifestations include gastrointestinal, cutaneous, and respiratory symptoms appearing 2–6 h after the consumption of mammalian ...

Improving distribution models of sparsely documented disease vectors by incorporating information on related species via joint modeling

Ecography, Volume 2025, Issue 3, March 2025.
A necessary component of understanding vector‐borne disease risk is accurate characterization of the distributions of their vectors. Species distribution models have been successfully applied to data‐rich species but may produce inaccurate results for sparsely documented vectors. In light of global change, vectors that are currently not well‐documented

Geographic Variation in the Prevalence of Candidatus Neoehrlichia procyonis in Raccoons (Procyon lotor) in the United States and Canada

MicrobiologyOpen, Volume 14, Issue 1, February 2025.
A total of 167/394 (42.4%) raccoons were positive for Candidatus Neoehrlichia procyonis. Spatial variation was noted with higher prevalences in the Southeast region of the United States and in California. Ca. N. procyonis is widespread in raccoon populations, but the spatial variation in prevalence may be related to vector distribution or another ...

Attempted Transmission of Ehrlichia chaffeensis among White-tailed Deer by Amblyomma maculatum [PDF]

Journal of Wildlife Diseases, 2000
A deer was needle-exposed intravenously to Ehrlichia chaffeensis (Rickettsiales: Ehrlichieae) in canine macrophage (DH82) cells and 7 days later was infested with laboratory-reared Amblyomma maculatum (Koch) (Acari:Ixodidae) nymphs for acquisition feeding. After molting, the adult ticks were allowed to feed on a naive deer.
