Answer:
Schistosoma
Explanation:
The structural features of eggs of Schistosoma species are used to identify the infection caused by them. The species Schistosoma indicum produce microscopic oval eggs with a terminal spine. The eggs of Schistosoma nasale are also microscopic with a terminal spine. Presence of its spindle shaped spiny eggs in the nasal discharge confirms the infection.
Likewise presence of Schistosoma spindale in body is confirmed by identification of its spindle-shaped microscopic eggs with terminal or lateral spine. Hence, identification of microscopic spiny eggs of Schistosoma species helps in the diagnosis of the infection.
