Relevance. Small-scale farming on a private basis have some disadvantages. Many similar farms do not take timely measures to combat pest diseases, especially against helminthiasis pathogens. Echinococcosis was among the main helminth diseases in sheep in the Absheron Peninsula territories and the adjacent Khizi region too, where we conduct research. It’s widespread in Azerbaijan and greatly damaged sheep breeding. Reesults. During study, we detected the species of E. granulosus in sheep atall study points in the Absheron Peninsula and Khizi. Thus, the relative prevalence of invasion was recorded in the villages Tudar (47,9%), Jeyranbatan (47,6%), Altyagach (46,5%), and some low the percentage of infection in the villages of New Yashma (20,6%), Hovsan (21,8%), Mushvigabad (25,0%). Hence, analysis of the echinococcosis causative agent shows spread of this invasion throughout the farms in different forms. It has been studied in altitude belts too. There are such results: an invasion’s high extensiveness was recorded in the low-mountain (45,1%) zone.
