ABSTRACT
Background:The Kato-Katz thick smear technique is the standard technique recommended by the World Health Organisation for the quantitative diagnosis of Schistosoma mansoni and other intestinal helminth infections.The major problem of the technique is that a few hours after the preparation of slides hookworm eggs over clear and disappear due glycerin. Objective:To illustrate clear visibility of different helminth eggs microscopically in Odongo-Aginya method; substitution of malachite green with 7.5nigrosin in 10formalin and 5eosin in 10formalin. Method: Measured; strained stool specimen was stained with mixture of nigrosin/ eosin and covered with cellophane cover slips.The prepared slide was examined immediately microscopically. Result: Slides prepared with Odongo-Aginya method can be examined immediately or later without compromising the visibility of parasite eggs and larvae. Hookworm eggs remain visible for a long time. Conclusion:The present publication shows microscopic appearance of the helminth eggs using the Odongo-Aginya modification

We describe an innovative use of multimedia materials to support training and advocacy within a schistosomiasis control programme. The Schistosomiasis Control Initiative (SCI) at Imperial College London works with selected sub-Saharan African countries to develop schistosomiasis control programmes. Two elements of the SCI programme were supported by multimedia materials developed at the Wellcome Trust in collaboration with the SCI: (1) training of programme managers, district health officers, and those delivering practical elements of the programme; and (2) advocacy targeted at decision-makers and donors. Evaluation of the materials revealed high reported ratings for both user satisfaction and impact from use of the product. From this experience we draw out several general messages about development of multimedia materials and how these will play a growing future role in promoting training within international health.
