A great number of Egyptian workers and farmers are seeking settlement in Iraq and some of them proved to have either Schistosoma Haematobium (S.h.) or Schistosoma mansoni (S.m) or even mixed infection. Besides, there is the possibility that some of the Iraqi fresh water snails may prove to be susceptible to infection by one or both of the Schistosoma Egyptian strains. The present study deals with investigations on the susceptibility of Iraqi B. truncatus, Gyranaulus ehrenbergi, Physa c.f. fontinalis, Lymnea lagetis, Melanoides tuberculata and Melanopsis nodes by these parasites. Egyptian S. haematobium but not Egyptian S. mansoni infect Iraqi B. truncatus and both proved to be unable to infect any of the other snails included in the study. Yet, the number of cercariae shedded by B. truncatus snails infected with the Egyptian S. haematobium strain, was much less that the number of cercariae shedded by these snails when infected with the Iraqi S. Haematobium strain.
大量埃及工人和农民在伊拉克寻求定居，其中一些人被证实感染了埃及血吸虫（S.h.）或曼氏血吸虫（S.m），甚至是混合感染。此外，一些伊拉克淡水蜗牛有可能被埃及血吸虫的一个或两个菌株感染。本研究针对伊拉克截形小泡螺、艾氏环棱螺、类似泉生扁卷螺的膀胱螺、拉氏椎实螺、瘤拟黑螺和结节黑螺对这些寄生虫的易感性展开调查。埃及血吸虫能感染伊拉克截形小泡螺，但埃及曼氏血吸虫不能，而且二者均无法感染本研究中的其他任何蜗牛。然而，感染埃及血吸虫菌株的截形小泡螺释放的尾蚴数量，远少于感染伊拉克血吸虫菌株的这些蜗牛释放的尾蚴数量。
