Detection of Anaplasma phagocytophilum and Babesia aktasi in a wild bezoar goat (Capra aegagrus): Overlap with domestic goat strains

open access: yesMedical and Veterinary Entomology, Volume 40, Issue 1, Page 190-197, March 2026.
This study provides the first molecular detection of tick‐borne pathogens in Capra aegagrus. Genetic analysis reveals similarities between Babesia aktasi and Anaplasma phagocytophilum strains in bezoar and domestic goats, indicating potential pathogen exchange.

Exploring the Causal Links Between Toxoplasma gondii Infection and Risk of Brain Tumors: A Bidirectional Mendelian Randomization Analysis

open access: yesBrain and Behavior, Volume 16, Issue 2, February 2026.
Mendelian randomization (MR) analysis demonstrated that genetic liability to malignant brain tumors was significantly associated with increased odds of Toxoplasma gondii (T. gondii) seropositivity, suggesting that individuals genetically predisposed to brain tumors may have a higher susceptibility to T. gondii infection.

Development and Characterization of Microsatellite Genetic Markers for Hyalomma rufipes, a Tick Vector of Crimean‐Congo Hemorrhagic Fever Virus

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
This study developed and validated 14 polymorphic microsatellite markers to investigate the population genetics of Hyalomma rufipes, a tick species that transmits Crimean‐Congo Hemorrhagic Fever Virus (CCHFV) in East Africa. Ticks collected from livestock in northern Kenya were morphologically and genetically identified, followed by genome sequencing ...

Modulation of succinyl‐CoA:3‐ketoacid CoA transferase activity by a single amino acid residue in acetate:succinate CoA transferase from Trypanosoma brucei, the causative agent of African sleeping sickness

open access: yesProtein Science, Volume 35, Issue 2, February 2026.
Abstract Trypanosomatids are protozoan parasites that remain a global health challenge due to the limited efficacy, safety, and durability of current treatments. Acetate: succinate CoA transferase (ASCT), together with succinyl‐CoA synthase (SCS), forms the ASCT/SCS cycle that fuels ATP production and generates acetate, a central metabolic intermediate

Unravelling echinoid mass mortalities: a global overview of mechanisms, spatio‐temporal trends, and taxonomic insights

open access: yesBiological Reviews, Volume 101, Issue 1, Page 221-236, February 2026.
ABSTRACT Mass mortality events (MMEs) have been occurring since the dawn of time. However, in contrast to terrestrial events, most marine MMEs remain undetected, largely due to the inaccessibility of many marine environments. One of the most notorious and best‐studied marine MMEs in modern times is that of the population collapse of the echinoid ...
