Abstract

Filaments attached to trypanosomes of two strains of T. (T.) brucei were studied by electron microscopy and two distinct types identified: short-thick and long-thin. The former are associated with stumpy trypanosomes and are secretions, via the flagellar pocket, which originate in the area of the Golgi complex, during the infection of the host. They are referred to as 'secretory filaments'. Their diameter is 0.09 to 0.14 mum. The long-thin filaments are associated with slender forms of trypanosome in various artificial situations; those shown by negative staining are believed to be cytoplasmic extrusions from the anatomically weak extremities of the parasite and are referred to as 'plasmanemes'. Their diameter is 0.06 mum. Both types appear to maintain their structure without the aid of the normal type of unit membrane as myelin formations.

African Trypanosomiasis

African trypanosomiasis, also known as sleeping sickness, is an insect-borne parasitic disease of humans and other animals. It is caused by protozoa of the species Trypanosoma brucei and almost invariably progresses to death unless treated. Discover the latest research on African trypanosomiasis here.
