Comparative Analysis of the Distribution of the Cestode Infection Pathogen in the Internal Organs of Sheep in the Apsheron and Khizi Districts

During the research, cysts of Echinococcus granulosus and Cysticercus ovis were collected from the livers of sheep kept in Apsheron district. Echinococcus cysts were found in the whole liver and lungs of 302 out of 771 sheep examined. Among the study sites, Echinococcosiswas found in the villages of Tudar (47.9%), Jeyranbatan (47.6%), Altyagach (46.5%), Fatmayi (45.8%), and Kizilgazma (41.9%). Echinococcal cysts were collected from lungs and livers, and their distribution through organs was analyzed. As a result, in the livers, the intensity of invasion was 1-18 cysts, and in the lungs, it was 1-15 cysts. The high extent of invasion was recorded in the low mountain (45.1%) and foothills (42.5%) zones, and slightly less in the plain zone (32.7%). The infection rate of sheep increases from 28.3% in spring to 42.6% in summer and 48.5% in autumn, and these figures decrease again to 28.7% in winter. High infection with C. ovis species was recorded in Altyagach at 34.9%, Kizilgazma at 33.9%, and Tudar at 33.3%. In the villages of Mehdiabad, Sulutepe and Fatmayi, infection was not detected. C. ovis type is relatively low in the lowland zone with 8.8% EI, 1-8 II; in the areas belonging to the foothill zone, EI is 11.7%, EI is 1-8 units and is slightly higher; finally in the low mountainous zone, EI was 34.0%, EI was 1-19 units and was much higher. It was concluded from the research that the intensity of invasion due to both helminths was higher in Khizi district than Apsheron peninsula. Also, considering the altitude zones in the region, high intensity was recorded in the low mountainous zone.
