Abstract

A cross-sectional study was conducted to explore the prevalence of Trypanosome infections in cattle and within the tsetse flies from December 2020 to May 2021 in Dabo Hana district, Buno Bedelle Zone, Southwest Ethiopia. A total of 415 blood samples were examined utilizing Buffy coat and Giemsa-stained thin blood smear techniques. Vector distribution and tsetse fly infection rate were studied by deploying 60 traps in four purposively chosen villages of the district. The prevalence of Trypanosomes was 10.6% and 6.5% in cattle and in tsetse flies, respectively. Trypanosoma congolense (59.1%) in cattle and T. vivax (62.5%) in tsetse flies, were the foremost common species distinguished in the area. A significant difference (P ≤ 0.05) was observed in the prevalence of bovine Trypanosomosis between body condition scores of cattle. However, differences were not significant between coat color, sex, and age categories (P > 0.05). The mean PCV values of Trypanosome-infected cattle (22.6 ± 0.6) were significantly (P < 0.05) lower than those of non-infected cattle (25.6 ± 0.3). Out of 1441 flies caught, 1242 (86.2%) were Glossina, 113 (7.84%) were Stomoxys, and 86 (5.97%) were Tabanus. Of 1242 Glossina, 85% were G. tachinoides and the remaining 15% were G. m. sub-morsitans. This finding revealed that, three Trypanosoma species are circulating in cattle as well as in tsetse flies. It is recommended that, sustainable and integrated tsetse and Trypanosomosis control practices should be implemented to foster live stock health and agricultural development in the district. Other sensitive methods should be employed to determine the true picture of infection in the area.

埃塞俄比亚西南部Buno Bedelle区Dabo Hana区牛锥虫病病原学调查、病媒分布及采采蝇感染率研究

2020年12月至2021年5月，在埃塞俄比亚西南部布诺-贝德尔区的Dabo Hana区进行了一项横断面研究，以探讨牛和舌蝇中锥虫感染的流行率。使用Buffy coat和Giemsa染色的薄血涂片技术对总共415份血液样本进行了检查。通过在该地区四个有针对性的村庄部署60个诱捕器，研究了媒介分布和舌蝇感染率。锥虫体在牛和舌蝇中的患病率分别为10.6%和6.5%。牛的刚果锥虫（59.1%）和舌蝇的间日锥虫（62.5%）是该地区最常见的物种。牛的身体状况评分之间的牛锥虫病患病率存在显著差异（P≤0.05）。然而，毛色、性别和年龄类别之间的差异并不显著（P>；0.05）。感染锥虫体的牛的平均PCV值（22.6±0.6）显著低于未感染的牛（25.6±0.3）。在1441只苍蝇中，1242只（86.2%）是舌蝇，113只（7.84%）是口蝇，86只（5.97%）是肛门蝇。在1242个Glossina中，85%是G.tachinoides，其余15%是G.m.sub-morsitans。这一发现表明，有三种锥虫在牛和舌蝇中传播。建议实施可持续和综合的舌蝇和锥虫病控制措施，以促进该地区的活畜健康和农业发展。应该采用其他敏感的方法来确定该地区感染的真实情况。

期刊介绍： Veterinary Parasitology: Regional Studies and Reports focuses on aspects of veterinary parasitology that are of regional concern, which is especially important in this era of climate change and the rapid and often unconstrained travel of people and animals. Relative to regions, this journal will accept papers of the highest quality dealing with all aspects of disease prevention, pathology, treatment, epidemiology, and control of parasites within the field of veterinary medicine. Also, case reports will be considered as they add to information related to local disease and its control; such papers must be concise and represent appropriate medical intervention. Papers on veterinary parasitology from wildlife species are acceptable, but only if they relate to the practice of veterinary medicine. Studies on vector-borne bacterial and viral agents are suitable, but only if the paper deals with vector transmission of these organisms to domesticated animals. Studies dealing with parasite control by means of natural products, both in vivo and in vitro, are more suited for one of the many journals that now specialize in papers of this type. However, due to the regional nature of much of this research, submissions may be considered based upon a case being made by the author(s) to the Editor. Circumstances relating to animal experimentation must meet the International Guiding Principles for Biomedical Research Involving Animals as issued by the Council for International Organizations of Medical Sciences (obtainable from: Executive Secretary C.I.O.M.S., c/o W.H.O., Via Appia, CH-1211 Geneva 27, Switzerland).
