The superiority of the miniature Anion-Exchange Centrifugation Technique for detecting low grade trypanosome parasitaemias. 1984

R Sachs

The efficiency was tested of the Haematocrit Centrifugation Technique (HCT) and the miniature Anion-Exchange Centrifugation Technique (mAECT) for demonstrating trypanosomes in the blood of four antelopes experimentally infected with Trypanosoma brucei gambiense in Liberia. During simultaneous daily application of both methods over a period of six months, parasitaemias were detected on 12 occasions by HCT and on 73 occasions by mAECT during 473 examination days, thus indicating the superiority of the mAECT for the detection of low grade trypanosome infections.

D007474 Ion Exchange Reversible chemical reaction between a solid, often one of the ION EXCHANGE RESINS, and a fluid whereby ions may be exchanged from one substance to another. This technique is used in water purification, in research, and in industry. Exchange, Ion

D001769 Blood The body fluid that circulates in the vascular system (BLOOD VESSELS). Whole blood includes PLASMA and BLOOD CELLS.
D002498 Centrifugation Process of using a rotating machine to generate centrifugal force to separate substances of different densities, remove moisture, or simulate gravitational effects. It employs a large motor-driven apparatus with a long arm, at the end of which human and animal subjects, biological specimens, or equipment can be revolved and rotated at various speeds to study gravitational effects. (From Websters, 10th ed; McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
D006400 Hematocrit The volume of packed RED BLOOD CELLS in a blood specimen. The volume is measured by centrifugation in a tube with graduated markings, or with automated blood cell counters. It is an indicator of erythrocyte status in disease. For example, ANEMIA shows a low value; POLYCYTHEMIA, a high value.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001188 Artiodactyla An order of mammals which consists of the even-toed ungulates and includes both RUMINANTS and SWINE. Hippopotamus,Peccary,Peccaries
D014353 Trypanosomiasis, African A disease endemic among people and animals in Central Africa. It is caused by various species of trypanosomes, particularly T. gambiense and T. rhodesiense. Its second host is the TSETSE FLY. Involvement of the central nervous system produces "African sleeping sickness." Nagana is a rapidly fatal trypanosomiasis of horses and other animals.
