| molecular identification of different trypanosome species and subspecies in tsetse flies of northern nigeria. | 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. although some of them can be mechanically transmitted by biting flies; these trypanosomes are all transmitted by tsetse flies which are the cyclical vectors of trypanosoma congolense, t. godfreyi, t. simiae and t. brucei. we present here the first report asse ... | 2016 | 27216812 |
| an atlas of tsetse and bovine trypanosomosis in sudan. | after a long period of neglect, initiatives are being implemented in sudan to control tsetse and trypanosomosis. their planning, execution and monitoring require reliable information on the geographic distribution of the disease and its vectors. however, geo-referenced and harmonized data at the national level are lacking, despite the fact that a number of epidemiological studies were conducted over the years. the atlas of tsetse and bovine trypanosomosis in sudan tries to fill this gap. | 2016 | 27056678 |
| the wing venation patterns to identify single tsetse flies. | this is the first study to explore the potential of various geometric morphometrics methods to help the morphological diagnostic of tsetse species, vectors of human and animal trypanosomiases in sub-saharan africa. we compared landmarks, semilandmarks and outlines techniques on male and female samples of species, and suggested adapted strategies according to the countries and their own glossina fauna. we could compare up to 7 taxa belonging to the three main subgenera of the glossina genus: nemo ... | 2017 | 27765637 |
