Five-Year Slaughterhouse-Based Surveillance of Echinococcus granulosus in Sheep from Yili, Northwest Xinjiang, China.

ABSTRACT:

Background

Cystic echinococcosis (CE) remains a significant zoonotic burden in the pastoral regions of China. Yili Prefecture in Xinjiang is a high-risk area, yet comprehensive data are lacking on the prevalence and molecular characteristics of Echinococcus granulosus in its primary intermediate host, sheep.

Methods

From 2020 to 2024, a total of 2700 sheep livers were visually inspected for hydatid cysts infection at one randomly selected slaughterhouse in each of the nine counties of Yili Prefecture. Ninety cyst-positive samples were subjected to morphological examination and molecular genotyping by amplifying and sequencing the nad2 gene.

Results

The overall prevalence of E. granulosus was 22.0% (594/2700). County-level prevalence ranged from 18
