FASCIOLOSIS IN CATTLE IN UZBEKISTAN AND KARAKALPAKSTAN: EPIZOOTOLOGICAL FEATURES, PATHOANATOMICAL CHANGES, AND DIAGNOSTIC METHODS – A COMPREHENSIVE STUDY
Abstract
This article analyzes the epizootology, invasion intensity, and pathoanatomical changes of fasciolosis in cattle across nine regions of Uzbekistan and the Republic of Karakalpakstan, based on research conducted over 15 years. Studies indicate that in the foothill-mountain zones, the prevalence of fasciolosis in cattle averages 64.5%, with an invasion intensity of 42 parasites. Age-based indicators show that the number of parasites averages 33.6 in one-year-old cattle, 42.2 in two-year-olds, and 42 in older cattle. In Samarkand region, the average prevalence of fasciolosis is 43.7%, with an invasion intensity of 95.5 parasites, highlighting the dominance of F. gigantica as the primary causative agent.
Additionally, the article compares these findings with research conducted in Russia, Chechnya, and other countries, discussing the development of fasciolosis and similar helminthic diseases, diagnostic methods, and clinical-pathoanatomical changes. Based on the results of this study, scientific recommendations have been developed for rapid diagnosis, prevention, and treatment plans. The findings are of significant relevance in improving local veterinary practices and enhancing the quality of beef products.
