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

Genetic exchange in Trypanosoma brucei: evidence for mating prior to metacyclic stage development [PDF]
It is well established that genetic exchange occurs between Trypanosoma brucei parasites when two stocks are used to infect tsetse flies under laboratory conditions and a number of such crosses have been undertaken.

Activation of endocytosis as an adaptation to the mammalian host by trypanosomes [PDF]
Immune evasion in African trypanosomes is principally mediated by antigenic variation, but rapid internalization of surface-bound immune factors may contribute to survival.

The Spermatophore in Glossina morsitans morsitans: Insights into Male Contributions to Reproduction. [PDF]
Male Seminal Fluid Proteins (SFPs) transferred during copulation modulate female reproductive physiology and behavior, impacting sperm storage/use, ovulation, oviposition, and remating receptivity.

Background Tsetse flies are vectors of human and animal African trypanosomiasis. In spite of many decades of chemotherapy and vector control, the disease has not been eradicated. Other methods like the transformation of tsetse fly symbionts to render the

Equine trypanosomiasis, a systematic review: Disease management
Abstract Background Equine trypanosomiasis is a neglected protozoal disease. Objectives To answer the study question: In equines what are the effects of disease management of trypanosomiasis on disease severity (individual level) and disease prevalence (population level) compared to no intervention? Study Design Systematic review.
