Question

In addition to undergoing development in the blood Trypanosoma also invades

• A. Lymphatic glands
• B. Cerebrospinal fluid
• C. Spinal fluids
• D. All of the above

Answer 1

The correct option is D All of the above

Trypanosomes are ingested by a Tsetse fly when it feeds on the blood of an infected animal. The trypanosome metacyclics develop further here, invade the local lymph vessels and then move into the bloodstream. The ensuing infection is characterized by successive waves of parasitaemia in the bloodstream, as parasite populations multiply rapidly and die off. The infected animal may die or eliminate the parasites and recover. T. vivax and T. brucei parasites may also invade an animal's connective tissues, and in the final stages of the disease, T. brucei may invade the central nervous system.

Thus, the correct answer is option D.
