Investigating the unaccounted ones: insights on age-dependent reproductive loss in a viviparous fly

Frontiers in Ecology and Evolution, 2023
Most empirical and theoretical studies on reproductive senescence focus on observable attributes of offspring produced, such as size or postnatal survival. While harder to study, an important outcome of reproduction for a breeding individual is whether a

Development and characterization of microsatellite markers for the tsetse species Glossina brevipalpis and preliminary population genetics analyses

Parasite, 2023
Tsetse flies, the vectors of African trypanosomes are of key medical and economic importance and one of the constraints for the development of Africa.

Developing a national atlas to support the progressive control of tsetse-transmitted animal trypanosomosis in Kenya

Parasites & Vectors, 2020
Background African animal trypanosomosis (AAT) is a major livestock disease in Kenya. Even though, over the years various organizations have collected a vast amount of field data on tsetse and AAT in different parts of the country, recent national-level ...

Molecular identification of different trypanosome species and subspecies in tsetse flies of northern Nigeria [PDF]

, 2016
Background: Animal African Trypanosomiasis (AAT) is caused by several species of trypanosomes including Trypanosoma congolense, T. vivax, T. godfreyi, T. simiae and T. brucei. Two of the subspecies of T. brucei also cause Human African Trypanosomiasis.

The Spermatophore in Glossina morsitans morsitans: Insights into Male Contributions to Reproduction. [PDF]

, 2016
Male Seminal Fluid Proteins (SFPs) transferred during copulation modulate female reproductive physiology and behavior, impacting sperm storage/use, ovulation, oviposition, and remating receptivity.

No evidence for direct thermal carryover effects on starvation tolerance in the obligate blood‐feeder, Glossina morsitans morsitans

Ecology and Evolution, 2023
Thermal stress during development can prime animals to cope better with similar conditions in later life. Alternatively, negative effects of thermal stress can persist across life stages and result in poorer quality adults (negative carryover effects ...

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

Micromachines, 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 ...

Split-Cre-mediated GFP expression as a permanent marker for flagellar fusion of Trypanosoma brucei in its tsetse fly host

mBio
Trypanosomes have different ways of communicating with each other. While communication via quorum sensing, or by the release and uptake of extracellular vesicles, is widespread in nature, the phenomenon of flagellar fusion has only been observed in ...

The importance of wild meat and freshwater fish for children's nutritional intake in the Congo Basin

People and Nature, EarlyView.
Abstract Wild meat and freshwater fish are widely consumed in the Congo Basin, but in some areas, they are at risk of disappearing due to unsustainable hunting and fishing and changes in their habitat. Wild meat is also at risk of being eliminated from local diets due to potential policy changes such as wild meat bans.

Spatial Distribution of Trypanosomes in Cattle From Western Kenya

Frontiers in Veterinary Science, 2020
African Animal Trypanosomiasis (AAT) is a tsetse-transmitted protozoan disease endemic in “the tsetse belt” of Africa. Past studies investigating the epidemiology of the disease rarely focused on spatial distribution when reporting the prevalence.
