Development of the livestock pathogen Trypanosoma (Nannomonas) simiae in the tsetse fly with description of putative sexual stages from the proboscis

Parasites & Vectors, 2023
Background Tsetse-transmitted African animal trypanosomiasis is recognised as an important disease of ruminant livestock in sub-Saharan Africa, but also affects domestic pigs, with Trypanosoma simiae notable as a virulent suid pathogen that can rapidly ...

NK Cells Are Critical for Optimal Immunity to Experimental Trypanosoma congolense Infection

Journal of Immunology, 2019
Key Points Deficiency of NK cells leads to enhanced susceptibility to T. congolense infection. NK cells mediate protection during T. congolense infection via perforin.

Trypanosoma congolense: In Vitro Culture and Transfection [PDF]

Current Protocols in Microbiology, 2019
AbstractTrypanosoma congolense, together with T. vivax and T. brucei, causes African animal trypanosomiasis (AAT), or nagana, a livestock disease carried by bloodsucking tsetse flies in sub‐Saharan Africa. These parasitic protists cycle between two hosts: mammal and tsetse fly.

Preliminary application and evaluation of loop-mediated isothermal amplification (LAMP) for detection of bovine theileriosis and trypanosomosis in Tanzania : research communication

Onderstepoort Journal of Veterinary Research, 2007
The sensitivity of LAMP, PCR and microscopy to detect Theileria spp. and Trypanosoma congolense in field-derived bovine blood samples from Tanzania was evaluated and compared. No parasites were detected by microscopy.

Characterisation of the surface coat of Trypanosoma congolense

Nature, 1978
THE protozoan parasites Trypanosoma congolense, T. brucei and T. vivax cause extensive disease problems to livestock in Africa1. In many cases trypanosomiasis results from mixed infections due to all three species2. Immunisation has not been successful because of the ability of the parasites to evade the host immune response by changing the antigenic ...

Expression profiling of Trypanosoma congolense genes during development in the tsetse fly vector Glossina morsitans morsitans

Parasites & Vectors, 2018
The tsetse transmitted parasitic flagellate Trypanosoma congolense causes animal African trypanosomosis (AAT) across sub-Saharan Africa. AAT negatively impacts agricultural, economic, nutritional and subsequently, health status of the affected populace ...

Sex, subdivision, and domestic dispersal of Trypanosoma cruzi lineage I in southern Ecuador. [PDF]

, 2010
BACKGROUND: Molecular epidemiology at the community level has an important guiding role in zoonotic disease control programmes where genetic markers are suitably variable to unravel the dynamics of local transmission. We evaluated the molecular diversity

Shape-shifting trypanosomes: Flagellar shortening followed by asymmetric division in Trypanosoma congolense from the tsetse proventriculus

PLoS Pathogens, 2018
Trypanosomatids such as Leishmania and Trypanosoma are digenetic, single-celled, parasitic flagellates that undergo complex life cycles involving morphological and metabolic changes to fit them for survival in different environments within their ...
