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.

Challenges facing the elimination of sleeping sickness in west and central Africa: sustainable control of animal trypanosomiasis as an indispensable approach to achieve the goal

Parasites & Vectors, 2015
African trypanosomiases are infectious diseases caused by trypanosomes. African animal trypanosomiasis (AAT) remains an important threat for livestock production in some affected areas whereas human African trypanosomiasis (HAT) is targeted for ...

Evaluation of two candidate molecules—TCTP and cecropin—on the establishment of Trypanosoma brucei gambiense into the gut of Glossina palpalis gambiensis

Insect Science, EarlyView.
This study investigates the potential of enhancing the resistance of Glossina palpalis gambiensis to Trypanosoma brucei gambiense to mitigate the transmission of Human African Trypanosomiasis. We successfully cloned genes encoding proteins of interest in Sodalis strains, resulting in recombinant Sodalis (recSodalis) that were micro‐injected into the L3

Effect of Spiroplasma infection on the mating behavior of Glossina fuscipes fuscipes

Insect Science, EarlyView.
Abstract Tsetse flies are insects of significant public health and zoonotic importance as they are the main vectors of African trypanosomes. To date, an effective vaccine is unavailable and efforts to limit the spread of the disease primarily rely on controlling the tsetse populations.

Reemergence of Human African Trypanosomiasis Caused by Trypanosoma brucei rhodesiense, Ethiopia

Emerging Infectious Diseases
We report 4 cases of human African trypanosomiasis that occurred in Ethiopia in 2022, thirty years after the last previously reported case in the country. Two of 4 patients died before medicine became available.

Stress in dipteran insects mass‐reared for sterile insect technique applications

Insect Science, EarlyView.
The connections between biotic and abiotic stress affecting mass‐reared dipteran insects and the associated stress and immunological responses. Numbers indicate the order in which the topics are discussed in this review. Abstract Stress may be viewed as the disturbance of homeostasis of an organism.

Zebra stripes: the questions raised by the answers

Biological Reviews, EarlyView.
ABSTRACT Multiple hypotheses have been suggested to explain why the three zebra species (Equus quagga, E. grevyi and E. zebra) are striped. We review how well these theories explain the nature (rather than simply the existence) of the stripes. Specifically, we explore how well different theories explain (i) the form of zebra stripes (especially on ...

Artificial intelligence‐powered microscopy: Transforming the landscape of parasitology

Journal of Microscopy, EarlyView.
Abstract Microscopy and image analysis play a vital role in parasitology research; they are critical for identifying parasitic organisms and elucidating their complex life cycles. Despite major advancements in imaging and analysis, several challenges remain. These include the integration of interdisciplinary data; information derived from various model

Trypanocidal and leishmanicidal activity of six limonoids [PDF]

, 2020
Six limonoids [kotschyienone A and B (1, 2), 7-deacetylgedunin (3), 7-deacetyl-7-oxogedunin (4), andirobin (5) and methyl angolensate (6)] were investigated for their trypanocidal and leishmanicidal activities using bloodstream forms of Trypanosoma ...

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

Journal of Microscopy, EarlyView.
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.
