During studies on schistosomiasis in Saudi Arabia, urine and stool samples from inhabitants of various areas (mostly rural) were examined, and 97 aquatic habitats in 46 localities were searched for snails. The results indicate the occurrence of both urinary and intestinal schistosomiasis in most parts of the country, with a patchy distribution and varying infection rates. The snail intermediate host of Schistosoma mansoni was found to be Biomphalaria arabica. For S. haematobium three species of snails, namely, Bulinus truncatus and B. beccarii in the west and B. reticulatus wrighti in the northeast, may transmit the infection; the susceptibility of the two former species has been confirmed in the laboratory. The limitation in the size of snail habitats--which consist of wells, small canals, cisterns, small swamps, interrupted streams, and ponds--creates a special type of transmission which can be defined as "oasis transmission," making control of the disease both simple and practical.
在沙特阿拉伯开展血吸虫病研究期间，对不同地区（主要是农村地区）居民的尿液和粪便样本进行了检测，并在46个地点的97个水生栖息地中搜寻钉螺。结果表明，该国大部分地区均出现了泌尿生殖系统血吸虫病和肠道血吸虫病，分布呈片状，感染率各异。已发现阿拉伯双脐螺是曼氏血吸虫的中间宿主钉螺。对于埃及血吸虫，西部的截形泡螺和贝克氏泡螺以及东北部的网纹泡螺wrighti亚种这三种钉螺可能会传播感染；前两种钉螺的易感性已在实验室得到证实。钉螺栖息地规模有限，包括水井、小运河、蓄水池、小沼泽、断流溪流和池塘，这形成了一种特殊的传播类型，可定义为“绿洲传播”，使得该病的防控既简单又可行。
