A study on Schistosoma incognitum, a blood fluke of a variety of mammals, was conducted in different ecological conditions in Phitsanulok and Phichit, northern Thailand. The intermediate host of S. incognitum in permanent water habitats studied, i.e; swamps and ditches is Radix (Lymnaea) auricularia rubiginosa. Of 44,412 mollusks representing 13 different species collected from 24 water habitats studied, 7,186 were R. a. rubiginosa. S. incognitum infection rate in the snails was 2.1%. 483 Rattus rattus, 8 R. argentiventer, 280 Bandicota indica and 65 B. savilei were found infected with S. incognitum with an overall infection rate of 41.7%. R. argentiventer and B. savilei are reported as new mammalian hosts of the parasite. Also, 3.9% of dogs in the study area were found excreting S. incognitum eggs in their stools for the first time. The possibility of S. incognitum as a zoonotic potentiality to humans is discussed and is still an equivocal issue deserving further study.
在泰国北部彭世洛府和披集府的不同生态条件下，对一种寄生于多种哺乳动物的血吸虫——隐匿血吸虫进行了研究。研究中发现，隐匿血吸虫在永久性水域栖息地（即沼泽和沟渠）的中间宿主是耳萝卜螺（Lymnaea auricularia rubiginosa）。从24个研究水域栖息地采集的代表13个不同物种的44412只软体动物中，有7186只是耳萝卜螺。蜗牛中隐匿血吸虫的感染率为2.1%。发现483只黑家鼠、8只银腹家鼠、280只板齿鼠和65只萨氏板齿鼠感染了隐匿血吸虫，总体感染率为41.7%。银腹家鼠和萨氏板齿鼠被报告为该寄生虫新的哺乳动物宿主。此外，研究区域内3.9%的狗首次被发现粪便中排出隐匿血吸虫卵。文中讨论了隐匿血吸虫对人类具有人畜共患的可能性，这仍是一个有待进一步研究的模糊问题。
