Macrophotograph of a tsetse fly Glossina morsitans,a major vector of sleeping sickness,feeding on a human arm. The abdomen of the fly can be seen filling with human blood. Sleeping sickness is mainly a disease of tropical Africa and is caused by the presence in the blood of a parasitic protozoa Trypanosoma gambiense or T. rhodesiense. These parasites are transmitted to man through the bite of the tsetse fly. Magnification: x2 at 35mm size | |
