Question

Monocystis belongs to the order

• A. Eugregarinida
• B. Coccidia
• C. Microsporidia
• D. Sarcosporidia

Answer 1

The correct option is A Eugregarinida

Monocystis is an endoparasite in the seminal vesicle and coelom of earthworms. The feeding stage is called trophozoite that develops within the sperm morula, which is a group of developing sperms in the seminal vesicles of an earthworm. Eugregarinorida is the largest and diverse order of gregarines (parasitic protists).

Coccidia is a subclass of spore-forming, single-celled obligate intracellular parasites which can infect all mammals and some birds, fish, reptiles and amphibians.

Sarcosporidia is an order of Coccidia.

Microsporidia constitute a group of spore-forming, unicellular, parasitic fungi.

Thus, the correct answer is option A.
