Abstract

Hydatid disease caused by Echinococcus granulosus (E. granulosus) represents a significant public health and economic problem. This zoonosis remains endemic in some regions of Algeria. The objectives of the study were to investigate the prevalence of hydatid cysts in cattle and sheep slaughtered at the slaughterhouse in Batna, Northeast Algeria, and characterize associated lesions through histopathology. A cross-sectional study was conducted from December 2018 to December 2019, where 13,903 cattle and sheep passed through post-mortem examination of lungs and liver for cyst detection. Samples were collected for histological analysis. Prevalence was compared between species and affected organs, while risk factor determination was based on sex, age, and season. The prevalence of hydatid cysts was significantly higher in cattle (2.16 ± 0.5%) compared to sheep (0.54 ± 0.1%) (P < 0.001), suggesting a species-related susceptibility. In both species, cysts mainly affect the lungs. The prevalence varied significantly based on age, sex, and seasonal factors. The risk of hydatidosis significantly increases in females (P < 0.0001; OR = 151.47, 95% CI = 63.57-360.92) and adults (P < 0.0001; OR = 10.63, 95% CI = 4.65-24.30) ruminants, especially in summer (P < 0.046; OR = 2.14, 95% CI = 1.01-4.54). The histopathological examination revealed various cyst sizes with reactional layers related to host inflammation. Hydatid disease remains endemic in Batna. Comprehensive control through meat inspection, condemnation of infected organs, and dog deworming programs are needed to reduce the public health risks and economic impacts of this critical zoonosis. Improved surveillance allows informed intervention design and assessment of control measures.
