在塞内加尔河下游三角洲三个村庄附近的传播点，对曼氏血吸虫和埃及血吸虫的潜在中间宿主种群进行了一年的研究。 Biomphalaria pfeifferi被发现分布广泛且数量日益丰富，由于其能够承受温度变化和夏眠的能力，它似乎很好地适应了新的灌溉地区（由迪亚马和马南塔利的水坝创建）。该物种是曼氏沙门氏菌在雨季期间强烈传播的原因。相比之下，负责传播埃及沙门氏菌（发生在旱季）的物种球布林菌（Bulinus globosus）的分布更为有限。这两种蜗牛分布的变化似乎与当地生态的变化有关，而当地生态的变化本身就是三角洲最近的水开发计划的结果。
The populations of the potential intermediate hosts of Schistosoma mansoni and S. haematobium were studied for a year at transmission sites near three villages in the lower delta of the Senegal River. Biomphalaria pfeifferi, found to be widely distributed and increasingly abundant, appears to be well adapted to the new areas of irrigation (created by the dams at Diama and Manantali) thanks to its ability to withstand changes in temperature and to aestivate. This species is responsible for intense transmission of S. mansoni during the rainy season. In contrast, Bulinus globosus, the species responsible for the transmission of S. haematobium (which occurs during the dry season), had a more limited distribution. The changing distributions of these two snail species appear to be linked to changes in local ecology, themselves the result of the recent programme of water-development in the delta.
