trypanosome

A scientist observes a trypanosome under a microscope.

Definition

1. Noun:
   • A parasitic protozoan: "trypanosome" refers to any of various flagellate protozoans of the genus Trypanosoma, which are parasitic in the blood or tissues of vertebrates (including humans) and are typically transmitted by insect vectors, such as the tsetse fly. These parasites cause serious diseases like sleeping sickness and Chagas disease.

Usage Examples

• Noun:
  • The trypanosome is the causative agent of African sleeping sickness. (The parasitic protozoan causes the disease.)
  • Researchers are studying how the trypanosome evades the host's immune system. (Scientists are investigating the parasite's survival mechanisms.)

Advanced Usage

• "trypanosome infection": the condition of being infected with trypanosomes.

  • Trypanosome infection can lead to severe neurological symptoms if untreated. (The parasitic disease affects the brain and nervous system.)

• "trypanosome transmission": the process by which the parasite moves from vector to host.

  • Trypanosome transmission occurs through the bite of an infected tsetse fly. (The parasite enters the body via the insect's bite.)

Variants and Related Words

• Trypanosomal (adj): relating to or caused by trypanosomes.

  • Trypanosomal diseases are prevalent in sub-Saharan Africa. (Diseases caused by trypanosomes are common in that region.)

• Trypanosomiasis (n): the disease caused by trypanosome infection.

  • Trypanosomiasis, or sleeping sickness, is a serious health threat. (The disease is named for its neurological effects.)

Synonyms

• Flagellate: a protozoan with a whip-like appendage (flagellum); trypanosomes are a type of flagellate.
• Parasite: an organism that lives on or in a host and benefits at the host's expense.

Related Idioms

• "a trypanosome in the blood": a metaphorical phrase used in medical contexts to describe a hidden or persistent threat.
  • The infection was like a trypanosome in the blood — silent but dangerous. (The disease was asymptomatic yet harmful.)
