Question

Note the following features and choose the ones applicable to Wuchereia bancrofti.

A) Coelozoic parasite
B) Histozoic parasite
C) Monogenetic parasite
D) Digenetic parasite
E) Monomorphic acoelomate parasite
F) Dimorphic pseudocoelomate parasite

• A. B, C, F
• B. B, D, F
• C. A, C, F
• D. B, C, E

Answer 1

The correct option is B B, D, F

• Coelozoic parasites live within the cavities of the host's body.
• Histozoic parasite lives in between the cells of the tissue or organs of the host. For example, Wuchereria bancrofti lives in the lymph tissue and so is holozoic.
• A monogenetic parasite is a parasite that completes its life cycle in only one host.
• A digenetic parasite is a parasite that requires at least two hosts to complete its life cycle. W. bancrofti, carry out their life cycle in two hosts. Humans serve as definitive host and mosquitoes are intermediate hosts.
• W. bancrofti exhibits sexual dimorphism (i.e., is dioecious) and is pseudocoelomate, meaning it has a three-layered body that has a fluid-filled cavity (pseudocoelom) between the endoderm and the mesoderm.
• W. bancrofti is histozoix, digenetic, dimorphic pseudocoelomate.

Thus, the correct answer is an option (B).
