Cystic echinococcosis in cattle slaughtered at a slaughterhouse in Gessa, southern Ethiopia.

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.
