First report of Ophiotaenia sp. in frogs (Amietophrynus kassasii) from Egypt and in vitro anticestodal activity of Sinularia sp. Extract

This study documents the first occurrence of <i>Ophiotaenia</i> sp. in <i>A. kassasii</i> in Egypt and provides evidence that <i>Sinularia</i> sp. extract possesses strong, dose-dependent anticestodal properties. The pronounced tegumental damage observed suggests potent cestocidal mechanisms. These findings offer new insights into amphibian parasitology in Egypt and support the potential development of marine-derived natural products as alternative anthelmintics.
