Abstract

Cystic echinococcosis (CE) is a major medical and veterinary concern in the world. It is one of the significant diseases in livestock farming communities managed under extensive grazing system like Ethiopia. Domestic intermediate hosts are an important reservoir for the disease spread. A cross-sectional study was conducted to determine the occurrence and economic losses associated with CE in cattle slaughtered at Mekaneyesuse Municipality abattoir, South Gondor zone of Amhara Region, North West Ethiopia. Ante-mortem inspection, postmortem examinations of organs, hydatid cyst characterization and financial loss estimations were conducted. The study was conducted on 384 cattle. The involvement of different organs was as follows: lungs (46.09%), liver (45.22%), heart (6.09%), and kidneys (2.6%). Out of the total of 115 cysts observed, small cysts constituted 57.39%, medium-sized were 34.78%, and large cysts accounted for 7.83%. Of these 115 cysts, 53.9% were fertile which included both viable (29%) and non-viable (71%) cysts. Furthermore, 46.1% cysts were non fertile, 62.3% were sterile and 37.7% were calcified. Based on the origin of animal, the prevalence of hydatid cysts was recorded to be 31.25%, 24%, 22.05% and 14.25% in Tachgayent, Semada, Andabet and Estie district, respectively. Higher cyst occurrence was observed in animals with poor body condition (51.56%) followed by medium (13.7%) and good body condition scores (8.25%). The total annual economic loss due to the direct condemnation of organs and indirect losses were estimated to be 851,252.68 ETB ($16,061.06). This study revealed that CE is economically important disease at Mekaneyesuse, South Gondar Zone, Amhara Region, Northwest Ethiopia. A more comprehensive investigation is required on prevalence and genotyping of Echinococcus granulosus s.l. cysts is important also to identify and estimate the relative contribution of each species or genotype to the disease in this area. Moreover, efforts to enhance public awareness in the area should also be pursued.

牛囊性棘球蚴病流行病学研究：埃塞俄比亚西北部 Mekaneyesuse 市屠宰场调查、囊肿特征及其经济影响

囊性棘球蚴病（CE）是全世界医学和兽医学关注的一大问题。它是埃塞俄比亚等广泛放牧的畜牧业社区的主要疾病之一。家畜中间宿主是疾病传播的重要贮存库。我们开展了一项横断面研究，以确定埃塞俄比亚西北部阿姆哈拉地区南贡多尔市 Mekaneyesuse 市屠宰场屠宰的牛中 CE 的发生率和相关经济损失。研究人员进行了宰前检查、宰后器官检查、水囊肿特征描述和经济损失估算。研究对象为 384 头牛。不同器官的受累情况如下：肺（46.09%）、肝（45.22%）、心脏（6.09%）和肾（2.6%）。在观察到的 115 个囊肿中，小型囊肿占 57.39%，中型囊肿占 34.78%，大型囊肿占 7.83%。在这115个囊肿中，53.9%为可育囊肿，包括可育囊肿（29%）和不可育囊肿（71%）。此外，46.1%的囊肿不能生育，62.3%不能生育，37.7%钙化。根据动物的来源，塔奇盖恩特、塞马达、安达贝特和埃斯提区的包虫病发病率分别为 31.25%、24%、22.05% 和 14.25%。体况较差的动物囊肿发生率较高（51.56%），其次是体况中等（13.7%）和体况良好（8.25%）的动物。据估计，每年因器官直接损失和间接损失造成的经济损失总额为 851 252.68 埃提（16 061.06 美元）。这项研究表明，CE 是埃塞俄比亚西北部阿姆哈拉地区南贡达尔区 Mekaneyesuse 的重要经济疾病。需要对棘球蚴包囊的流行率和基因型进行更全面的调查，这对于确定和估计各物种或基因型对该地区疾病的相对贡献也很重要。此外，还应努力提高该地区公众的认识。

期刊介绍： Parasite Epidemiology and Control is an Open Access journal. There is an increasing amount of research in the parasitology area that analyses the patterns, causes, and effects of health and disease conditions in defined populations. This epidemiology of parasite infectious diseases is predominantly studied in human populations but also spans other major hosts of parasitic infections and as such this journal will have a broad remit. We will focus on the major areas of epidemiological study including disease etiology, disease surveillance, drug resistance and geographical spread and screening, biomonitoring, and comparisons of treatment effects in clinical trials for both human and other animals. We will also look at the epidemiology and control of vector insects. The journal will also cover the use of geographic information systems (Epi-GIS) for epidemiological surveillance which is a rapidly growing area of research in infectious diseases. Molecular epidemiological approaches are also particularly encouraged.
