“…No attempt seems to have been made to monitor S. manosoni during this period. The situation deteriorated during World War II and intestinal bilharzia replaced urinary infection as the main parasite (Stephenson, 1947). In 1952, Greany examined over 80,000 people and found 8.77% were infected with S. mansoni and 8.86% with S. haematobium (Greany, 1952).…”

This paper analyses the changing patterns of infection with Schistosoma mansoni and S. haematobium in the Gezira Irrigation Scheme, Sudan. Taking a historical perspective, it shows the way in which factors such as ecology, biology, social and economic variables and politics have shaped patterns of infection, and how different kinds of strategies have been developed to control schistosomal infection over time. Wider political and economic issues at both national and international levels have shaped these strategies, influencing the prevalence and intensity of schistosomal infection at a local level. By highlighting the inter-play between the above-mentioned factors, the article reflects on the wisdom of prioritizing community-directed mass drug administration for the control of schistosomiasis in Gezira and elsewhere. The review demonstrates that not all efforts to control schistosomiasis are sustainable. A comprehensive control strategy involving political commitment, community participation and socioeconomic development is important for sustainable control of schistosomal infection.

“…Durante as últimas décadas, foram adotados métodos pouco sensíveis, mas bastante práticos para determinar a presença de moluscos, quer em levantamentos de fauna malacológica, quer em controle de densidade de população, antes e após o uso de moluscocidas. Para atender a estes objetivos, o uso de drogas, conchas metálicas, homens/hora, folhas de palmeira, etc, se mostraram bastante eficientes (STEPHENSON 14 ; DOBROVOLNEY & BARBOSA 5; OLIVER & SCHNEIDERMAN ") No entanto, sua eficiência é duvidosa para determinar ou estimar densidade populacional, apesar de ainda estarem em uso em estudos epidemiológicos da esquistossomose. Sua eficiência qualitativa é inegável, mas a quantitativa deve ser encarada com reservas.…”

Propõe-se um novo método de marcação de planorbídeos para determinação de densidade e de outros parâmetros pertinentes ao estudo de dinâmica de população, como capacidade de migração, taxas de crescimento e potencial biótico nos habitats naturais. Consiste em marcação através de dois furos de cerca de 2 mm de diâmetro de cada lado da concha em sua extremidade anterior, usando-se um estilete metálico. Após a marcação os caramujos são imediatamente reintroduzidos no habitat, em local correspondente ao da captura processada poucos minutos antes. Nos experimentos realizados, as taxas de caramujos marcados, recapturados uma semana após a marcação, variaram de 14 a 18% e permitiram calcular a população total de B. glabrata, de 5 mm de diâmetro ou mais. O método permite estimar também a população de jovens com menos de 5 mm e fazer marcações múltiplas. É muito simples, de fácil manejo, não exige equipamentos nem pessoal especializados e provoca menos impacto no ambiente do que outros métodos.

“…In 1927, an epidemiological survey was conducted among children in twenty settlements, where not a single child was reported to be infected in the area, in spite of the presence of the intermediate hosts (Humphreys, 1932). Then the prevalence of Schistosoma haematobium in the Gezira area was found to be 15% among adults and 45% in Children Stephenson (1947). Malek (1962) reported the prevalence of 5% of Schistosoma haematobium at Wad Medani.…”

The varied climatic environment of the Sudan has considerable influence on the distribution of snails. Thus, the occurrence of snails in different parts of the Sudan was reported.Archibald (1933), reported the presence of Bulinus forskalii in springs in the Nuba mountains in western Sudan. Doumenge et al, (1987) mentioned that Bulinus truncatus, the intermediate host of Schistosoma haematobium, seems to tolerate drought and as thus it is the most widespread in Darfur, Kordofan and the area around Kassala. It is also well established in the Nile below Khartoum. Doumenge et al, (1987) also reported the occurrence of Biomphalaria pfeifferi, the intermediate of Schistosoma mansoni, in Jebel Marra area, western Sudan and in the area around Juba in Southern Sudan. Recently, both Bulinus and Biomphalaria snails were found in Jonglei canal region, southern Sudan (Brown et al, 1984).
