The skin is a significant but overlooked anatomical reservoir for vector-borne African trypanosomes

eLife, 2016
The role of mammalian skin in harbouring and transmitting arthropod-borne protozoan parasites has been overlooked for decades as these pathogens have been regarded primarily as blood-dwelling organisms.

Infections With Extracellular Trypanosomes Require Control by Efficient Innate Immune Mechanisms and Can Result in the Destruction of the Mammalian Humoral Immune System

Frontiers in Immunology, 2020
Salivarian trypanosomes are extracellular parasites that affect humans, livestock, and game animals around the world. Through co-evolution with the mammalian immune system, trypanosomes have developed defense mechanisms that allow them to thrive in blood,

African Trypanosomes undermine humoral responses and vaccine development : link with inflammatory responses? [PDF]

Frontiers in Immunology, 2017
African trypanosomosis is a debilitating disease of great medical and socioeconomical importance. It is caused by strictly extracellular protozoan parasites capable of infecting all vertebrate classes including human, livestock, and game animals.

Shared species of crocodilian trypanosomes carried by tabanid flies in Africa and South America, including the description of a new species from caimans, Trypanosoma kaiowa n. sp.

Parasites & Vectors, 2019
Background The genus Trypanosoma Gruby, 1843 is constituted by terrestrial and aquatic phylogenetic lineages both harboring understudied trypanosomes from reptiles including an increasing diversity of crocodilian trypanosomes.

Parasite motility is critical for virulence of African trypanosomes. [PDF]

Scientific Reports, 2018
African trypanosomes, Trypanosoma brucei spp., are lethal pathogens that cause substantial human suffering and limit economic development in some of the world's most impoverished regions.

Trypanosomes of the Trypanosoma theileri Group: Phylogeny and New Potential Vectors

Microorganisms, 2022
Trypanosomes belonging to Trypanosoma theileri group are mammalian blood parasites with keds and horse fly vectors. Our aim is to study to vector specificity of T. theileri trypanosomes.

Avian Louse Flies and Their Trypanosomes: New Vectors, New Lineages and Host–Parasite Associations

Microorganisms, 2022

Cyclic AMP signalling and glucose metabolism mediate pH taxis by African trypanosomes

bioRxiv, 2021
The collective movement of African trypanosomes on semi-solid surfaces, known as social motility, is presumed to be due to migration factors and repellents released by the parasites.

Diversity and Epidemiology of Bat Trypanosomes: A One Health Perspective

Pathogens, 2021
Bats (order Chiroptera) have been increasingly recognised as important reservoir hosts for human and animal pathogens worldwide. In this context, molecular and microscopy-based investigations to date have revealed remarkably high diversity of Trypanosoma
