Cystic echinococcosis is caused by the metacestode of the zoonotic flatworm . A cross-sectional study was conducted from October 2020 to August 2021 at the Gessa municipality abattoir in southern Ethiopia, through regular meat examinations and cyst characterization to determine the prevalence, organ distribution, and fertility of Cystic echinococcosis. The overall prevalence of was 17.9% (69/384) and has shown a statistically significant association ( < 0.05) with the body condition of cattle but not with other putative risk factors ( > 0.05). The odds of poor body condition cattle infected with CE was 1.29 times higher than medium body condition (OR = 0.506; CI = 0.566-2.96). Based on organ distribution of cysts, the lungs and liver were the most affected organs having a statistically significant difference ( < 0.05) with the prevalence of CE. Based on the size of cysts, small (47.9%) size cysts revealed the highest prevalence as compared with large (33.3%) and medium (18.8%) sized cysts. On cyst characterization, the majority of Cystic echinococcosis were sterile cysts (55.4%) followed by fertile (38.8%) and calcified (8.7%) cysts and revealed a statistically significant difference ( < 0.05). Cyst number, organ localization, fertility of cyst, and cyst size have shown a strong positive correlation ( = 0.8686, = 0.8393, = 0.9506, and = 0.9189) with the prevalence of CE, respectively. The presence of an overall high prevalence of in the present study required urgent action to interrupt the life cycle of Cystic echinococcosis and further studies using molecular techniques to characterize the circulating genotypes to prevent the risk of zoonosis in humans in the study area.
囊型包虫病由一种人畜共患扁形虫的中绦期幼虫引起。2020年10月至2021年8月，在埃塞俄比亚南部的盖萨市屠宰场进行了一项横断面研究，通过定期的肉类检查和囊肿特征分析来确定囊型包虫病的患病率、器官分布和繁殖力。总体患病率为17.9%（69/384），与牛的身体状况存在统计学显著关联（P<0.05），但与其他假定风险因素无关联（P>0.05）。身体状况差的牛感染囊型包虫病的几率比身体状况中等的牛高1.29倍（OR=0.506；CI=0.566 - 2.96）。根据囊肿的器官分布，肺和肝是受影响最严重的器官，其囊型包虫病患病率存在统计学显著差异（P<0.05）。根据囊肿大小，小囊肿（47.9%）的患病率最高，相比之下，大囊肿（33.3%）和中囊肿（18.8%）的患病率较低。在囊肿特征方面，大多数囊型包虫病囊肿为不育囊肿（55.4%），其次是可育囊肿（38.8%）和钙化囊肿（8.7%），且存在统计学显著差异（P<0.05）。囊肿数量、器官定位、囊肿繁殖力和囊肿大小与囊型包虫病的患病率分别呈现出强正相关（r=0.8686、r=0.8393、r=0.9506和r=0.9189）。本研究中囊型包虫病总体患病率较高，需要采取紧急行动来阻断囊型包虫病的生命周期，并开展进一步研究，采用分子技术来鉴定循环基因型，以预防研究区域内人类感染人畜共患病的风险。
