Cultivating Lithoglyphopsis aperta Temcharoen, a new snail host for Schistosoma japonicum, Mekong strain.
Lithoglyphopsis aperta Temcharoen, a new intermediate host for Schistosoma japonicum, Mekong strain, was cultivated successfully through the F2 generation with the use of a petri dish aquarium provided with mud and alga. The incubation period of eggs was about 4 weeks; the young grew to maturity in 16 to 20 weeks; egg-laying followed about 6 to 8 weeks later, the cycle taking roughly 6 months. The husked eggs were deposited exclusively at the edge and wall of the aquarium. Eggs were hemispherical and with the husks were between 0.37 and 0.43 mm in diameter. The newly hatched young were only 0.24 mm in shell length and the full-grown snails were 3.11 to 3.36 mm long. Logarithmic growth began between the 12th and 14th weeks.
