Abstract

Bovine fasciolosis caused by Fasciola hepatica and Fasciola gigantica, is a neglected tropical snail-borne trematode disease of cattle that poses an adverse effect on animals' health culminating in economic damage. Cross-sectional investigation on coprological and postmortem assessment and economic significance of bovine fasciolosis in cattle slaughtered at Tarcha Municipal Abattoir, Southern Ethiopia through simple random sampling techniques was conducted from December 2020 to August 2021. Out of 384 cattle examined, 20.3% and 29.94% were found harboring Fasciola through coprological examination and postmortem examination respectively. The leading cause of fasciolosis in the study area was Fasciola gigantica (53.9%) as compared to F. hepatica (46.1%). The investigation revealed that the sex, origin, and body condition of the cattle has a statistically significant effect on the prevalence of bovine fasciolosis. The odds of male animals infested with fasciolosis were 2.25 times higher than female cattle and those of poor body-conditioned cattle were three times higher than cattle with good body condition. In postmortem examination, an average of 6 flukes were found in a single infested liver and the mean fluke count was (10 ± 1.97) in severely infested livers while in lightly infested livers (3± 1.79). Considering postmortem examination as the gold standard for diagnosis of fasciolosis, the sensitivity of the direct sedimentation technique was found to be 68% and the specificity 100% with substantial agreement (k = 0.74) between the two methods. The estimated yearly direct financial losses incurred owing to fasciolosis was around 2,227,536 2, Birr (47,945.24 USD). Thus, bovine fasciolosis is one of the economically important animal diseases in the study area, which necessitates integrated control measures to tackle its effect on animal health and subsequent economic impact.

埃塞俄比亚南部Tarcha市屠宰场屠宰的牛片形虫病的粪学和死后评估及其经济意义

由肝片形吸虫和巨型片形吸虫引起的牛片形吸虫病是一种被忽视的热带蜗牛传播的牛吸虫病，对动物健康造成不利影响，最终导致经济损失。通过简单随机抽样技术，于2020年12月至2021年8月对埃塞俄比亚南部塔尔查市屠宰场屠宰的牛进行了牛片形吸虫病的粪学和死后评估及其经济意义的横断面调查。384头被检牛中，经粪学检查和死后检查，片形虫感染率分别为20.3%和29.94%。研究区片形吸虫病的主要病因为巨型片形吸虫(53.9%)，其次为肝片形吸虫(46.1%)。调查显示，牛的性别、来源和身体状况对牛片吸虫病的流行有统计学上显著的影响。公牛感染片形虫病的几率是母牛的2.25倍，体质差的牛是体质好的牛的3倍。尸检中单个感染肝脏平均检出6只吸虫，重度感染肝脏平均吸虫数为(10±1.97)只，轻度感染肝脏平均吸虫数为(3±1.79)只。将尸检作为诊断片形虫病的金标准，直接沉降法的灵敏度为68%，特异性为100%，两种方法基本一致(k = 0.74)。据估计，每年因片形吸虫病造成的直接经济损失约为2,227,5362,000,000比尔(47,945.24美元)。因此，牛片形吸虫病是研究区经济上重要的动物疾病之一，需要采取综合控制措施来解决其对动物健康的影响和随之而来的经济影响。

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.
