为进一步弄清阿曼南方地区曼氏血吸虫病和埃及血吸虫病流行情况及其媒介螺,作者在阿曼西南部佐法尔省的6个地区进行了现场调查。在取样的16个调查点中有15个点水体中都发现有密度不等的阿拉伯双脐螺(Biomphalaria arabica)。经实验观察,其中13个点的螺均有曼氏血吸虫尾蚴逸出,另2个点的螺逸出的为非血吸虫尾蚴。用自一个最大水体取得的78只阿拉伯双脐螺进行实
In order to further understand the prevalence of Schistosoma mansoni and schistosomiasis in southern Oman and its serogroups, the authors conducted field surveys in six districts of Dhofar province in southwestern Oman. Biomphalaria arabica of unequal density was found in 15 of 16 sampled water samples. The experimental observation, of which 13 points snail have Schistosoma mansoni cercariae escape, the other two points of the snail escaped non-schistosome cercariae. Realizations were made with 78 Arabidopsis thallus obtained from one of the largest bodies of water
