Ultrastructural expansion microscopy reveals unexpected levels of glycosome heterogeneity in African trypanosomes

Journal of Microscopy, Volume 301, Issue 2, Page 222-240, February 2026.
Abstract Kinetoplastid parasites include several species. Trypanosoma brucei causes African sleeping sickness in humans and a wasting disease nagana in livestock. Trypanosoma cruzi is the causative agent of Chagas disease and Leishmania species cause leishmaniasis, which can present with visceral, cutaneous, or mucocutaneous symptoms.

Amphibian Strategies Against Attacks by Flies: Host‐Specificity and Threats

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Species interactions between Diptera flies and amphibians play a significant role in tropical ecosystems, but their ecology and evolution remain understudied. This review explores the costs flies impose on amphibians, such as pathogen transmission and disruption of communication systems, and highlights the evolutionary strategies employed by both ...

Standardization of bovine macrophage monolayers and isolation and culture of trypanosomes

Memorias do Instituto Oswaldo Cruz, 2003
We describe a method for culturing over 90% pure bovine macrophages from peripheral blood mononuclear cells separated with Nycoprep. The cells were cultured for 12 days and then stained with esterase and with anti CD14 to test for purity.

Seasonal Dynamics and Associated Risk Factors of Bovine Trypanosomosis and Its Vector in Selected Districts of Gamo and Gofa Zones, Southern Ethiopia

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
The median PCV of poor body‐conditioned animals is below 20 (anaemic) compared to corresponding body‐condition animals. Black‐ and red‐coloured animals are more significantly affected by trypanosomosis than white‐coloured animals. Multivariable logistic regression revealed more about contributory factors than univariable logistic regression.

Tim17 Updates: A Comprehensive Review of an Ancient Mitochondrial Protein Translocator

Biomolecules, 2020
The translocases of the mitochondrial outer and inner membranes, the TOM and TIMs, import hundreds of nucleus-encoded proteins into mitochondria. TOM and TIMs are multi-subunit protein complexes that work in cooperation with other complexes to import ...

Comparative gene expression of Wigglesworthia inhabiting non-infected and Trypanosoma brucei gambiense-infected Glossina palpalis gambiensis flies

Frontiers in Microbiology, 2014
Tsetse flies (Glossina sp.) that transmit trypanosomes causing human (and animal) African trypanosomiasis (HAT and AAT, respectively) harbor symbiotic microorganisms, including the obligate primary symbiont Wigglesworthia glossinidia.
