以不感受任何地方的日本血吸蟲之高雄產台灣釘螺分別與宜蘭或彰化產台灣釘螺交配繁殖重組子代，試驗此等重組子代對日本血吸蟲的感受性之變化。 所得結果表示重組子代對於日本血吸蟲的感受性與宜蘭及彰化產釘螺比較，有明顯的減低，尤其高雄、宜蘭間的重組子代的感受性比較高雄、彰化間重組子代的感受性有明顯的減低。此等重組釘螺之感受性，不受親代釘螺性別之影響。
- 英文摘要：
It is known that Oncomelania hupensisformosana from Kaohsiung is resistant to allstrains of Schistosoma japonicum, while thesnail from Ilan is only susceptible to Ilanparasite and the snail from Changhua is sus-ceptible to Changhua and Ilan parasites. Inthe present studies, recombinant snails be-tween Kaohsiung and Ilan or Changhua snailswere produced in the laboratory, and the sus-ceptibility of these recombinants to infectionwith S. japonicum was investigated. The re-combinants from Kaohsiung and Ilan parentalsnails were exposed to the Ilan strain of S. japonicum, whereas the recombinants fromKaohsiung and Changhua parental snails to theChanghua Parasite. Each experiment utilizedthe respective race of O.h. formosana ex-posed to S. japonicum as control. Results obtained indicated that suscepti-bility of recombinant snails to infection withS. japonicum decreased significantly as com-pared with the I1an and Changhua control sn-ails, especially those of Kaohsiung and Ilanrecombinants. The susceptibility of recom-binants was not affected by the sex of paren-tal snails.
