| maintaining zebu maure cattle in a tsetse infested area of mali. | a study was initiated to evaluate two trypanocidal drugs, the prophylactic isometamidium chloride (trypamidium) and the curative diminazene aceturate (berenil) as to their potential for long-term maintenance of zebu cattle in a tsetse infested area of mali. trypamidium was administered quarterly and berenil was administered only as animals were found to be positive for trypanosomes. during the 21-month study trypanosomiasis was the most frequently encountered disease in the cattle in the berenil ... | 1984 | 6729998 |
| pathogenesis and pathology of african trypanosomosis in baoulé, n'dama/baoulé cross bred and zebu cattle in burkina faso. 1. clinical performance under high natural tsetse challenge. | the pathogenesis and pathology of african animal trypanosomosis (aat) in baoulé, n'dama/baoulé-cross-bred and zebu cattle was studied from 1987 to 1991 in a series of experiments conducted under natural and artificial conditions of challenge at the centre de recherches sur les trypanosomoses animales (crta) in burkina faso. this first paper reports on the clinical performance of 64 baoulé, 10 n'dama/baoulé-cross-bred and 20 zebu cattle, which were transferred to the pastoral zone of satiri, 50 k ... | 1993 | 8367674 |
| experimental infection of n'dama cattle with trypanosomes using glossina palpalis gambiensis caught in the wild. | the transmissibility of trypanosome infection to n'dama cattle by tsetse flies caught in the field was examined. wild-caught glossina palpalis gambiensis were transferred singly into small numbered cages and allowed to feed on 14 uninfected n'dama cattle. following a completed feed the tsetse were dissected and infection in the proboscis, the salivary glands and the gut was recorded. each animal was bitten by a number of tsetse ranging from five up to 64 flies. following dissection of the tsetse ... | 1990 | 2321260 |
| trypanosoma vivax in glossina palpalis gambiensis do not appear to affect feeding behaviour, longevity or reproductive performance of the vector. | feeding behaviour of glossina palpalis gambiensis vanderplank infected with trypanosoma vivax ziemann was studied and compared with that of uninfected control tsetse. the parameters measured were: total number of probes into the ear-skin of rabbits; rate of bloodmeal engorgement; weight of freshly ingested blood; survival; and mean weight of pupae. the results showed that the rosettes of t.vivax parasites in the labrum did not interfere with the feeding behaviour of the vectors. furthermore, mea ... | 1991 | 1768899 |
| new epidemiological features on animal trypanosomiasis by molecular analysis in the pastoral zone of sideradougou, burkina faso. | a multidisciplinary work was undertaken in the agropastoral zone of sidéradougou, burkina faso to try to elucidate the key factors determining the presence of tsetse flies. in this study the pcr was used to characterize trypanosomes infecting the vector (glossina tachinoides and glossina palpalis gambiensis) and the host, i.e. cattle. a 2-year survey involved dissecting 2211 tsetse of the two glossina species. a total of 298 parasitologically infected tsetse were analysed by pcr. trypanosoma viv ... | 1998 | 9691491 |
| bovine trypanosomosis in the upper west region of ghana: entomological, parasitological and serological cross-sectional surveys. | baseline surveys were conducted in the upper west region of ghana to assess the distribution and densities of tsetse species, as well as the prevalence of bovine trypanosomosis. the entomological survey was designed to cover the suitable tsetse habitats along the three main rivers in the study area (i.e. black volta, kulpawn and sissili). results indicated the presence of glossina tachinoides in all three river basins, whilst glossina palpalis gambiensis was only found close to the southern limi ... | 2011 | 21550616 |
| spatio-temporal distribution of tsetse and other biting flies in the mouhoun river basin, burkina faso. | in the mouhoun river basin, burkina faso, the main vectors of african animal trypanosomoses are glossina palpalis gambiensis vanderplank and glossina tachinoides westwood (diptera: glossinidae), both of which are riverine tsetse species. the aim of our study was to understand the impact of landscape anthropogenic changes on the seasonal dynamics of vectors and associated trypanosomosis risk. three sites were selected on the basis of the level of disturbance of tsetse habitats and predominant tse ... | 2010 | 21198714 |
| the prevalence of african animal trypanosomoses and tsetse presence in western senegal. | in 2005, the government of senegal initiated a tsetse eradication campaign in the niayes and la petite côte aiming at the removal of african animal trypanosomosis (aat), which is one of the main constraints to the development of more effective cattle production systems. the target area has particular meteorological and ecological characteristics that provide great potential for animal production, but it is unfortunately still infested by the riverine tsetse species glossina palpalis gambiensis v ... | 2010 | 21073148 |
| does isometamidium chloride treatment protect tsetse flies from trypanosome infections during sit campaigns? | african animal trypanosomosis is a major pathological constraint to cattle breeding across 10 million km2 of sub-saharan west african countries infested by tsetse flies, their cyclic vectors. the release of sterile males (sterile insect technique [sit]) is a potentially important control technique aimed at eliminating the vectors. prior to release, tsetse are generally treated with isometamidium chloride, a trypanocide, to prevent them from transmitting parasites. the present study investigated ... | 2008 | 18498613 |
| tsetse challenge, trypanosome and helminth infection in relation to productivity of village ndama cattle in senegal. | data on tsetse fly, and on village ndama cattle collected over a 4-year period in southern senegal, were analysed. a total of 431 ndama cattle in four herds of three villages in the upper casamance area of southern senegal were monitored monthly. glossina morsitans submorsitans and glossina palpalis gambiensis are present in the study area. mean tsetse apparent density was 5.4 flies/trap/day. trypanosome (trypanosoma congonlense and trypanosoma vivax) infection rate in flies was 2.4 (s.e. 0.37)% ... | 1999 | 10190867 |
