Ova in the stool is not of diagnostic significance in: (A) Stronyloides, (B) Entrobius, (C) Trichuris, (D) Ankylostoma
Answer is A. Strongyloides stercoralis:A specific diagnosis is based on the finding of the typical rhabditiform larvae in a freshly passed stool. A high eosinophilia is often a feature of strongyloidiasis. In pulmonary infection examination of the sputum will demonstrate the presence of rhabditiform larvae. So ova is not diagnostic of Strongyloides stercoralis.(Ref: K.D Chatterjee13th edition, p211)
