Распространение ценуроза овец и меры профилактики в Алматинской области Республики Казахстан

Abstract

Coenurosis in sheep is a severe cestode disease caused by the larval stage of Taenia multiceps and accompanied by damage to the central nervous system. The aim of the study was to assess the epizootological prerequisites for the spread of coenurosis in the Almaty region and to substantiate preventive measures. Along with an analysis of the literature, the results of a post-mortem examination of four yearling sheep from the peasant farm “Serik” of the Karasai district are presented. The animals were selected by the owner from a flock of about 200 head because of unusual behavior, lagging behind the flock and periodic throwing back of the head. At necropsy, 1-2 coenurus cysts, about the size of a pigeon’s egg, were found in each of the four brains. The pathological findings confirmed the diagnosis of coenurosis in all clinically suspected animals. Effective prevention should combine scheduled deworming of dogs, control of their access to sheep carcasses and heads, safe disposal of slaughterhouse waste and systematic recording of cases.
