“…According to Leak et al (1999), There was no significant difference (p > 0.05) in infection rate among thin, medium and good body condition. This result is similar to the work of Goossens et al (1998) and Snow et al (1996). These researchers have indicated that small ruminant are not often selected by tsetse flies.…”

A cross sectional study was conducted at Assosa zone of Benishangul Gumuz, North West Ethiopia, to determine the prevalence of trypanosomosis in local breeds of sheep and goats. Blood sample from 384 randomly selected sheep and goats (177 from Assosa and 207 from Homosha districts) of different species, sex, age groups were examined by dark phase contrast buffy coat and thin smear examination for species identification of trypanosome. Among the animals examined during the study period, 10 (2.6%) were infected with trypanosomes. From this survey, Trypanosoma vivax was found to be the major cause of trypanosomosis (1.82%), followed by Trypanosoma congolense (0.52%) and Trypanosoma brucei (0.26%). There was no statical difference (p > 0.05) in infection between sex, species, and among age groups. Mean packed cell volume (PCV) of the parastemic animals was significantly lower than (P < 0.05) that of aparastemic animals. In attempt to identify the vector involved in transmition, tsetse flies group (Glossina morsitans submorsitans) and mechanical vectors of trypanosomosis that belonging to Tabanidae (Tabanus, Stomoxys and Haematopota) were captured in both districts at an altitude range of 1270 to 1507 m above sea level. The results of the prevalence of the disease in small ruminants and its vectors indicate that an effective management and control measures for the disease and transmitting vectors should be designed and implemented.

“…Female cattle were found to be more often infected than males. This result was different from previous findings which reported no significant difference in prevalence of cattle trypanosomosis between sexes (3,17). The small sample size of calves, young and female cattle in the present study could be responsible for the observed differ ences in prevalence.…”

“…This may be due to the fact that although the natives had more often access to chemoprophylactics, most of the new settlers (94%) fed their cattle on crop residuals in confinement, which decreased the risk of infection, contrary to the natives who grazed their cattle in bush lands. Cattle which graze on bush land are more exposed to tsetse fly bite than cattle tethered within the village (17).…”

Une étude a été menée, d’octobre 2007 à avril 2008, à l’aide d’un questionnaire semi-structuré et d’échantillons sanguins dans la vallée du Ghibe, au sud-ouest de l’Ethiopie, pour évaluer la gestion des bovins exposés à la trypanosomose dans deux communautés, la population autochtone et les nouveaux colons. Des échantillons sanguins prélevés à l’oreille de 429 vaches (210 chez les autochtones et 219 chez les colons) ont révélé une prévalence globale de 5,4 p. 100, avec respectivement 6,2 et 4,6 p. 100 chez les autochtones et les colons. Cette différence entre les deux communautés n’a pas été significative (p > 0,45). Les informations qualitatives et quantitatives ont été obtenues à l’aide du questionnaire auprès de 50 autochtones et 51 colons sélectionnés de manière aléatoire. La plupart des pratiques de gestion du bétail chez les autochtones et chez les colons se sont avérées significativement différentes. Bien que la prévalence d’infection trypanosomienne n’ait pas été significativement différente entre les deux communautés, l’anémie a été rencontrée plus fréquemment chez les animaux des autochtones que chez ceux des colons. D’autres recherches devraient être menées afin de déterminer la raison principale qui a contribué à la différence observée entre les valeurs de l’hématocrite des deux communautés. Par ailleurs, l’attention vers une gestion efficace de la trypanosomose dans les deux communautés de la vallée du Ghibe est nécessaire pour améliorer les stratégies de prévention et de contrôle.

“…In The Gambia, the use of equine traction has grown rapidly (Sowe et al, 1987;Loum & Mbacke, 1989;Snow, et al, 1996;Faye et al, 2001, Secka, 2003. In 1987, Sowe et al indicated that the equine population in The Gambia was not self-sustaining as the high mortality and low foaling rates required sizeable purchases of donkeys and horses from neighbouring countries.…”

“…The authors stressed the need to identify the key determinants of this high mortality and poor reproductive performance and recommended that populations of horses and donkeys in districts with high mortality rates should be screened for trypanosomosis or signs of other diseases (Sowe et al, 1987). Trypanosomosis is one of the most important conditions affecting livestock productivity in The Gambia and equines are very susceptible (Snow et al, 1996, Starkey, 1990). …”
