A comparative analysis has been carried out between two populations of Schistosoma haematobium using the same intermediate snail host, Bulinus truncatus, but originating from two distinct ecological areas of Algeria: Khemis-El-Khechna in a sub-humid mediterranean zone and Djanet in a saharan bioclimatic zone. Four parameters have been studied: the growth rate of adult worms, size and shape of the eggs, chronobiology of cercarial emergence and the compatibility with the intermediate host. Results showing divergences for all the characters studied are discussed for the origin of this intraspecific polymorphism of S. haematobium in Algeria.
对来自阿尔及利亚两个不同生态区域的两种埃及血吸虫种群进行了比较分析。这两种埃及血吸虫使用相同的中间螺宿主截形泡螺，但分别来自阿尔及利亚的两个不同生态区域：半湿润地中海区域的凯米斯-埃尔-凯赫纳和撒哈拉生物气候区域的贾奈特。研究了四个参数：成虫的生长速率、虫卵的大小和形状、尾蚴逸出的时间生物学以及与中间宿主的相容性。针对阿尔及利亚埃及血吸虫这种种内多态性的起源，讨论了所有研究性状结果显示出差异的情况。
