Исходная информация: Эхинококкоз является инфекцией, вызванной личиночной стадией Echinococcus granulosus. Данное заболевание является зоонозом, распространенным во всем мире и характерен для развитых и слаборазвитых стран. Цели: Целью данного исследования является изучение зараженности эхинококками и предрасположенности мест повреждения гидатидой среди убитых животных в административном округе Асуан, южной части Египта, и изучение влияния возраста, пола животных и сезона года на заболеваемость эхинококками. Проведены макроскопическое и гистологическое исследования, растровая электронная микроскопия и гистопатологологические исследования обнаруженных при вскрытии убитых животных гидатид. Методы: Данное лабораторное обследование проводили с августа 2015 года по июль 2016 года в двух основных скотобойнях административного округа Асуан для изучения эхинококкоза у верблюдов и овец. Выводы: Всего исследовали 2080 верблюдов и 674 овец. Среди них у 173 верблюдов (8,32%) и у 3 овец (0,45%) были обнаружены переносчики одной или нескольких гидатид. Убитые животные женского пола и старшего возраста были более подвержены заражению данным плероцеркоидом, чем животные мужского пола и более молодого возраста. Гидатиды у убитых животных чаще всего обнаруживали в легком, менее часто - в печени, в то время как множественное заражение и в легком и в печени обнаруживали только у верблюдов. Более высокая встречаемость гидатид у убитых верблюдов была осенью, реже - зимой, в то время как гидатиды у убитых овец были обнаружены только в осенний период. Фертильные кисты в легких и печени убитых верблюдов составляли 83,4% и 30% соответственно, в то время как фертильные кисты в зараженных легких и печени овец составляли 100%. Основные выводы: Данное исследование показало, что убитые животные были заражены гидатидами в высокой возможно из-за существующих социально-экономических условий, благоприятных для развития заболевания и сохранения высокого уровня зараженности. Таким образом, обязательным является создание государственных программ контроля эхинококкоза для снижения уровня распространенности в административном округе Асуан и обеспечения эффективной защиты не только животных, но и людей от риска контактирования с инвазией.

Background: Hydatidosis is an infection caused by the cystic larval stage of Echinococcus granulosus. This disease is a zoonotic disease has a worldwide distribution and common in developing and undeveloped countries. Objectives: The objective of the present study is to studying the infection rate and predilection seats of hydatid cyst affections among slaughtered food animals in Aswan Governorate, southern Egypt and study the effect of age and sex of infected slaughtered animals on the infection with hydatid cyst. Also, study the effect of seasonal variations in the infection with hydatid cyst among slaughtered animals. In addition, the macroscopic examination, microscopic examination, scanning electron microscopy and histopathological studies for the collected hydatid cyst are examined. Methods: This investigation was carried out from August 2015 to July 2016 in two main slaughterhouses in Aswan Governorate to study the hydatidosis in camels and sheep. By routine meat inspection, hydatid cyst count and characterization was conducted. Findings: A total of 2080 camels and 674 sheep were examined. Of these, 173 (8.32%) camels and 3 (0.45%) sheep were found to harbour one or more hydatid cysts. Female and older age slaughtered animals were more susceptible to infection with these metacestode than males and younger animals. Hydatid cyst infection in slaughtered animals is most commonly found in lung followed by liver while mixed infection in both lung and liver was found only in camel. Hydatid cyst in slaughtered camels was higher in autumn followed by winter, while hydatid cyst in slaughtered sheep was found only in autumn season. Fertile cysts in lung and liver of slaughtered camels was 83.4% and 30% respectively. While the fertility of hydatid cyst in infected lung and liver of sheep was 100%. Main conclusions: This study reported that slaughtered animals were infected with relatively high infection rate of hydatid cyst may be due to the presence of socio-economic conditions favourable for the disease and maintenance of high level of infection. So must design governmental control programs against hydatidosis to minimize the infection rate in Aswan Governorate and ensure effective protection not only for animal population but also for humans at risk of contracting the infection.
