Chagas disease in Canadian blood donors: 15 years of selective testing

open access: yesVox Sanguinis, EarlyView.
Abstract Background and Objectives Chagas disease (Trypanosoma cruzi), prevalent in Mexico, Central and South America, can be transfusion‐transmitted. Selective serological testing of blood donors was implemented over 15 years ago. We describe the trends in infections and characteristics of donors selected for testing.

Prevalence of Haemoparasites among Blood Donors in Calabar, Nigeria

open access: yesMedical Laboratory Journal, 2021
Background and objectives: Voluntary blood donation is the main source of blood and its components globally. Blood transfusion is essential for management of various diseases but remains as one of the most important causes of disease transmission.

Synthesis, Electrochemistry, In Vitro Antiprotozoal Efficacy and Mechanistic Study of Novel ‘Ferrantoin’ and Related Derivatives

open access: yesApplied Organometallic Chemistry, Volume 40, Issue 7, July 2026.
1,2‐Disubstituted ferrocene analogues bearing hydantoin or rhodanine synthons were synthesised and assessed for antitrypanosomatid activity. An antileishmanial early lead, analogue 23, acting through ROS generation and hence oxidative stress, was uncovered.

Identification of Distinct Interacting Proteins of Giardia lamblia Centrins Using Yeast Two‐Hybrid Assays

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 4, July/August 2026.
ABSTRACT Giardia lamblia, a protozoan parasite that causes diarrhea in humans, contains two centrins implicated in cellular morphology and cell division. To identify proteins interacting with each G. lamblia centrin (GlCent), we performed a yeast two‐hybrid assay.

The Fantastic Voyage of the Trypanosome: A Protean Micromachine Perfected during 500 Million Years of Engineering

open access: yesMicromachines, 2018
The human body is constantly attacked by pathogens. Various lines of defence have evolved, among which the immune system is principal. In contrast to most pathogens, the African trypanosomes thrive freely in the blood circulation, where they escape ...

Structural Basis for Nucleobase Activation by the Adenine DNA Glycosylase MutY

open access: yesChemBioChem, Volume 27, Issue 11, 15 June 2026.
DNA glycosylase MutY engages its adenine nucleobase substrate in a syn orientation with a catalytic Glu. X‐ray crystal structures of MutY with Glu replaced suggest that a disengaged “on hold” state with anti nucleobase orientation may explain how MutY avoids catastrophic activity at inappropriate adenines.

Amélioration de la technique de salivation des glossines pour la détection des métatrypanosomes infectants : étude de quelques facteurs biologiques et non biologiques sur le comportement de sondage des glossines

open access: yesRevue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1995
Le comportement de sondage et de salivation sur lame chauffée est examiné chez trois espèces ou sous-espèces de glossines (Glossina morsitans morsitans, Glossina palpalis gambiensis, Glossina tachinoides) en fonction de certains paramètres (espèce, sexe,

Networks of Indirect Contact Promote Spread of an Environmentally Transmitted Pathogen in a Highly Social Species

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Using behavioral observations and network simulations, we evaluate direct and indirect transmission of the MTBC pathogen M. mungi in banded mongooses. Incorporating intergroup scent marking reveals that environmentally mediated, socially directed pathways can promote spread at low transmissibility, elevating population prevalence even when direct ...

Extracellular Vesicles of Giardia duodenalis: Unravelling Their Virulence Factors and Potential to Induce Protection Against Experimental Giardiasis

open access: yesJournal of Extracellular Biology, Volume 5, Issue 6, June 2026.
ABSTRACT Extracellular vesicles (EVs) are key mediators of intercellular communication, enabling trans‐kingdom exchange of proteins, nucleic acids, lipids, and metabolites. In Giardia duodenalis, EVs contribute to parasite survival, host–pathogen interactions, and immune modulation.

Trypanosoma (Duttonefla) vivax

open access: yesParasitology Today, 1987
Although Trypanosoma vivax was first discovered in 1905 (Ref. 1), the fact that most stocks of this parasite are restricted to ruminant hosts has retarded investigation of this species compared with the experimentally more amenable T. brucei and T. congolense. The veterinary importance of T. vivax (Box 1) and a recent report suggesting that T.
