Endocytosis in trypanosomes occurs via the flagellar pocket. Macromolecules enter the flagellar pocket from the outside of the cell and are then taken up by endocytosis. This picture shows particles of colloidal gold inside the flagellar pocket prior to endocytosis. Magnification: 80,000 ×.

The International Laboratory for Research on Animal Diseases (ILRAD) was established in 1973 with a mandate to develop effective control measures for livestock diseases that seriously limit world food production. ILRAD's research program focuses on African animal trypanosomiasis and East Coast fever, a form of theileriosis. ILRAD is one of 13 centres in a worldwide agricultural research network sponsored by the Consultative Group on International Agricultural Research. In 1988 funding for essential research and training activities was provided by the African Development Bank, the Rockefeller Foundation, the United Nations Development Programme, the World Bank (the International Bank for Reconstruction and Development) and the governments of Australia, Belgium, Canada, Denmark, France, India, Italy, Japan, the Netherlands, Norway, Sweden, Switzerland, the United Kingdom, the United States of America and West Germany. Additional research activities were supported by special funding arrangements from the European Economic Community and the World Health Organization and capital funds were provided by the Netherlands Government for construction of a new training and outreach building. |
This publication was typeset on a microcomputer and the final pages produced on a laser printer at ILRAD. The printing was done by Majestic Printing Works, Nairobi, Kenya.
