O‘zbekistonning turli geografik-iqlim mintaqalarida qo‘ylar moniyeziozining tarqalishi va mavsumiy o‘zgarishlari

The study aimed to determine the prevalence and seasonal variation of monieziosis in sheep under different geographical and climatic conditions of Uzbekistan. During 2021-2023, 2,465 sheep from the Republic of Karakalpakstan and 12 provinces were examined parasitologically. Fülleborn flotation, sequential washing sedimentation and a modified Berman-Orlov larvoscopic method were used. Monieziosis was detected in 123 animals, corresponding to an overall prevalence of 4.99% among the examined sheep. Prevalence reached 6.89% in foothill-mountain areas, 4.44% in irrigated areas and 3.44% in desert-pasture areas. Seasonal prevalence was highest in summer (35.8%), followed by spring (28.4%), autumn (23.6%) and winter (12.2%). In a separate field trial, a locally produced albendazole formulation, Alsus, showed an estimated extensive efficacy of 77.5% against monieziosis. The findings demonstrate pronounced geographical and seasonal variation in sheep monieziosis and support the use of locally adapted surveillance and control schedules.
