The Morphology and Biology of the Trematode Gigantobilharzia acotylea (Digenea, Schistosomatidae)
Morpho-biological traits of the trematode Gigantobilharzia acotylea Odhner, 1910 at all stages of ontogeny are studied. Mollusks Physa fontinalis and Anisus spirorbis widespread in the waterbodies of the Syrdarya River valley were found to be intermediate hosts of this trematode under natural and ex...

Изучены морфобиологические особенности трематоды Gigantobilharzia acotylea Odhner, 1910 во всех фазах онтогенеза. Промежуточными хозяевами трематоды в природных и экспериментальных условиях Узбекистана оказались моллюски Physa fontinalis и Anisus spirorbis. Они широко распространены в водоемах бассейна реки Сырдарьи. Общая зараженность партенитами и церкариями гигантобильгарций составила у P. fontinalis 0,4%, у A. spirorbis — 0,3%. В условиях эксперимента указанные моллюски заражаются до 100%. Продолжительность периода созревания церкарий в промежуточных хозяевах колеблется в зависимости от температуры и составляет 23–44 сут. Церкарии активно проникают через покровы тела птиц. В течение 30–35 сут они достигают половой зрелости: cамцы и самки приступают к размножению. На основе анализа морфобиологических особенностей рассматриваемых трематод предлагается комплекс признаков различных стадий развития, в частности церкарий, для дифференциации вида. 2010 Article The Morphology and Biology of the Trematode Gigantobilharzia acotylea (Digenea, Schistosomatidae) / F.D.
