Epizootology (epidemiology) of helminthozoonoses in the south-west of Republic of Kazakstan
Abstract
The purpose of the research: to educe regional specificity of epizootology (epidemiology) of helminthozoonoses (taeniarinhosis - cysticercosis, echinococcosis, trichinellosis) in Kyzylorda region Republic of Kazakstan. Materials and methods. In 2010-2016 according to postmortem examination methods cattle is investigated on cysticercosis and echinococcosis, sheep camels and horses on echinococcosis, pigs on taeniasis saginata at the premises of Kyzylorda meat cutting plant and at Kyzylorda markets. Physiological state of cysticercuses and caseworm larvocyst have been studied depending on the animal age. Invasion extensiveness (IE) of dogs were studied by the method of control worming by hydrobromide arecoline. As well as veterinarian and medical audit in region for the last 10 years was analyzed. Results and discussion. It has been established that cysticercosis bovine is widespread endemic and irregular. Invasion extensiveness (IE) of cattle was higher on the south-east of region (3.3%), and on the west this measure greatly declined (2.4%). This zoonosis extensiveness is greatly progressed during last 7 years (from 1.7% in 2010 till 3.3% in 2016). In general, at the south-west part of Kazakstan cattle is infected by Cysticercus bovis on 2.6-2.9% while the invasion strength (IS) is average 2-4 cysticercuses onto one corpse. During 2010-2016 it was educed two persons who are ill on taeniasis saginata. Sheep, cattle and camels were average taken by caseworms on 21.1%, 8.1%, and 42.7% respectively. IE parameters depended on the age and were high at the adult animals: Lambs are wormy on 2.5%, sheep older then 5 years on 29.5%, young camels at the age under 2 years are wormy on 27.9%, and animals older then 7 years on 50.0%, calves under 2 years are wormy on 2.4%, and cattle older then 5 years on 10.7%. IS of all kinds of animals correlated outright to EI and also depended on the animal age. In the process of internal veterinarian sanitary examination of 1680 killing horses of different age caseworm larvocyst were not founded. Эхинококкоз среди населения Кызылор динской области распространен эндемично. According to the data from health statistics, 463 patients (including 47.7% of men and 52.6% of women) have been operated concerning caseworm in the clinics in Kyzylorda region during 12 years (2005-2016 years). In 2010-2016 it was tested 688 samples of muscles of imported pork for trichinellosis by compressor method. All samples were negative. Over the last 10 years caseworm of animal and human was not registered in the region except one outburst in 2016 (February-March), during which 20 accidents of human caseworm had been educed in the region. The source of invasion was wild boars meat.
