摘要

背景：非洲动物锥虫病（AAT）是对动物健康和粮食生产产生持续有害影响的最严重疾病之一。方法：在埃塞俄比亚西南部布诺比德勒区比德勒区和德德萨区进行横断面研究，确定小反刍动物中锥虫病的流行情况和病媒分布。通过血液学分析对384只小反刍动物的血液样本进行了锥虫病检查。为了调查采采蝇的分布情况，我们在指定地区放置了72个捕蝇器。结果：血液学检查的小反刍动物（n = 384）中，16只（绵羊8只、山羊8只）感染锥虫。锥虫病总患病率为4.17 %。本研究仅发现间日绦虫和刚果锥虫两种，两者患病率相等（2.08 %）。寄生小反刍动物的PCV平均值 ± SD（24.37 ± 5.66）显著低于寄生小反刍动物的平均值（27.48 ± 4.38）。共捕获蝇类369只，其中速蝇（74.5 %）和褐家蝇（25.5 %），总平均表观密度为2.56只/笼/ d。结论：总的来说，这些结果表明这种疾病在这些动物中普遍存在，保持它们的健康可能在防御疾病的传播中发挥重要作用。需要更加重视在这些反刍动物中控制这种疾病，并且在非洲动物锥虫病控制活动的未来规划和战略中需要考虑这些动物作为疾病携带者的作用。

Survey on the prevalence of trypanosomosis in small ruminants and on tsetse distribution in Dedesa and Bedele districts, Buno Bedele Zone, Ethiopia

Background

African animal trypanosomosis (AAT) is one of the most serious diseases with ongoing detrimental effects on animal health and food production.

Methods

A cross-sectional study was conducted in the Bedele and Dedesa districts of Buno Bedele Zone, Southwest Ethiopia, to determine the prevalence of trypanosomosis and its vector distributions in small ruminants. Blood samples collected from a total of 384 small ruminants were examined for trypanosomosis via hematological analysis. For the tsetse distribution survey, 72 traps were deployed in the designated districts.

Results

Among the small ruminants examined with hematological techniques (n = 384), 16 (8 sheep and 8 goats) were infected with trypanosomes. The overall prevalence of trypanosomosis was 4.17 %. Only two species of trypanosomes, namely, T. vivax and T. congolense, were observed in this study, with equal prevalence rates (2.08 %). The mean PCV ± SD of the parasitemic small ruminants (24.37 ± 5.66) was significantly lower than that of the aparasitemic (27.48 ± 4.38) small ruminants. A total of 369 flies were caught (Glossina tachinoides (74.5 %) and G. morsitans (25.5 %)), with an overall mean apparent density of 2.56 flies per trap per day.

Conclusions

Overall, these results indicate that this disease is prevalent in these animals, and maintaining their health may play a significant role in defending the disease's spread. Greater emphasis needs to be given to controlling this disease in these ruminants, and the role of these animals as carriers of the disease needs to be considered in future planning and strategies of African animal trypanosomosis control activities.

期刊介绍： Comparative Immunology, Microbiology & Infectious Diseases aims to respond to the concept of "One Medicine" and to provide a venue for scientific exchange. Based on the concept of "Comparative Medicine" interdisciplinary cooperation between specialists in human and animal medicine is of mutual interest and benefit. Therefore, there is need to combine the respective interest of physicians, veterinarians and other health professionals for comparative studies relevant to either human or animal medicine . The journal is open to subjects of common interest related to the immunology, immunopathology, microbiology, parasitology and epidemiology of human and animal infectious diseases, especially zoonotic infections, and animal models of human infectious diseases. The role of environmental factors in disease emergence is emphasized. CIMID is mainly focusing on applied veterinary and human medicine rather than on fundamental experimental research.
