ABSTRACT
Introduction: Schistosomiasis; also known as bilharzia or snail fever; is a tropical parasitic disease caused by a trematode platyhelminthes called Schistosoma check for this species in other resources sp. Schistosoma species are transmitted by cercariae penetrating the skin when a person is bathing; washing clothes; fishing or engaged in agricultural activities; involving contact with fresh water that has fecal or urinary contamination; and contains the parasites' snail host. The present study aimed to survey freshwater snails in Kayonza District (Rwanda) especially Lake Muhazi and surrounding water bodies; stream and swamps to assess the potential for transmission of two species of Schistosoma: S. mansoni check for this species in other resources and S. haematobium check for this species in other resources. Methods: Six sites were selected to assess the potential for transmission of schistosomiasis. The intermediate hosts of schistosomes; namely the snails Biomphalaria check for this species in other resources ; Bulinus check for this species in other resources sp. and Lymnaea check for this species in other resources sp.; were collected and brought to the laboratory and investigated to see if trematode cercaria responsible for the disease were present. Results: Snails dissected were not only infected with trematode cercaria but also with annelids and flatworms (Platyhelminths). Cercaria found therein were of two types: furcocercous; probably responsible for schistosomiasis; and gymnocephalous cercaria for fasciolasis: an infection of cattle; goats and sheep. Conclusion: Biomphalaria sp were the major hosts for schistosome cercaria; and most snails collected of this species were infected. Moreover; they were found in large number from all sites. Lymnaea sp; hosts snails for Fasciola cercaria check for this species in other resources ; were also found in a considerable number compared to the low number of Bulinus sp in the region. District and national authorities may wish to further investigate this infestation and identify potential interventions to disrupt the disease transmission

Background: Schistosoma mansoni was observed and reported in Kuluva hospital Arua District in north western Uganda as early as 1902. S. mansoni is widely distributed in Uganda along permanent water bodies. Objective: To review the litreture on scistosomiasis in Uganda; since 1902. Method: The core literature for this short review was searched from reports and publications by the British colonial Ministry of Health Districts Medical officers and Entomologists. Additional information was obtained from Makerere University Medical School library archives; London School of Hygiene and Tropical Medicine library archives; University of Antrwap; and post independence publications on schistosomiasis in Uganda in various journals. Results: Since it was first detected in 1902 Schistosoma (S) mansoni is more widely distributed in Uganda than S. haematobium. However Schistosoma mansoni and S. haematobium are of public health importance in Uganda and the importance of migrants and fishermen in disseminating infections into non-infested areas and intensifying infection in areas already infested have been reported. Conclusion: S. mansoni has been on the increase in Uganda whereas S. haematobium is localized in sporadic foci in the north of Uganda. Treatment with praziquantel the drug of choice in Uganda used in schistosomiasis control programme has reduced development of severe schistosomiasis

Um Mocambicano de 44 anos apresentou-se com paraparesia dos membros inferiores e hematuria terminal; antecedentes de Febre de Katayama e de ter vivido nas margens do Lago Niassa nos tres meses precedentes ao inicio da doenca. O leucograma revelou eosinofilia (14 por centos) e a urina tinha ovos de Schistosoma Hematobium. Foi posto o diagnostico de schistosomiase vesical com acometimento de medula espinhal e feito o tratamento com praziquantel; predniosolona e fisioterapia; tendo recuperado a marcha apos dois meses de hosptalizacio

Les auteurs presentent les resultats d'une enquete echographique dont le but etait d'estimer la prevalence de la fibrose hepatique compliquant une bilharziose a schistosoma mansoni. En raison des images specifiques obtenues l'echographie se revele tres performante dans le diagnostic de la fibrose de symmers. Dans les etudes pratiquees sur le terrain; elle permet de connaitre avec precision la morbidite de la bilharziose a schistosoma mansoni qui jusque-la n'etait appreciee qu'indirectement par l'examen clinique
