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

HelminthsABSTRACT
A survey for intestinal schistosomiasis was carried out in grade six pupils (5;313 pupils; 10-15 years) in over 80of all primary schools in Kampal. The aim of the survey was to assess the prevalence and intensity of schistosomiasis in Kampala school children and to ascertain if transmission was occurring within the city. The prevalence of the disease was only 4.1(216/5;313) and egg load generally low (500 eggs per gram of stool). Most infected pupils came from areas outside Kampala known to be endemic for intestinal schistosomiasis. It cannot be precluded however; that some infections were contracted in Lake Victoria and the Kabaka's Lake within Kampala city. It was suggested that it would be more cost effective if schistosomiasis control measures were applied at this stage

Parasitic Diseases , SchistosomiasisABSTRACT
Four hundred and fifty one human strata living in the three fishing villages of Ndiaga; kabukanga and Rwabikongoro along Lake Albert shore in Kibale District were examined for S. mansoni infection using Kata/Katz method. Of the 451 people; 409(90.7) were found infected with S. mansoni with geometric mean egg count of 561.3 eggs per gram (epg) faeces. Males had significantly higher mean egg counts than females; 608.e epg and 415.6 epg respectively. All S. mansoni infected individuals were treated with praziquantel at 40mg/kg body weight. Other common parasites observed were Ascaris lumbricoides; Trichuris trichiura and hookworms. These were treated with mebandazole. Snail infection rate among the 115 Biomphalaria sudanica and the 56 B. stanleyi were 5.2and 3.6respectively. All the 66 Bulinus (B) tropicus found; were negative for cercariae shedding. The main pulmonate snails were 250 Lymnae natalensis; 500 Pila ovata and 375 Bellamya spp were the commonest prosobranchs followed by Bivalves (101)
