  • Biomphalaria glabrata와 Indoplanorbis exustus의 알에 대한 식물성 살패제 Brassaia actinophylla (Araliaceae)의 메탄올 추출물을 아치사 농도로 처리하였을 때 효과를 평가하였다. 그 결과 B. actinophylla를 10 mg/1 농도로 처리하였을 때, 두 종류의 패류의 배(embryo)에서 모두 변화를 보였다. Niclosamide를 0.004mg/1로 처리하였을 경우 역시 B. glabrata와 I. exustus의 배 발생을 억제하였다. 따라서 B. actinophylla는 주혈흡충증의 중간숙주는 패류 관리에 있어 세포치사제로 이용될 수 있을 것이다.

  • The present study examines the potential involvement of Biomphalaria glabrata, a known molluscan intermediate host of Schistosoma mansoni, in the life cycle of Echinostoma cinetorchis, one of the echinostomes that are ubiquitous parasites of vertebrates and are of importance in human and veterinary medicine and wildlife diseases. Echinostomes can be maintained easily and inexpensively in the laboratory and provide good models for biological research ranging from the molecular to the organismal. In the present study, no echinostome cercariae were released from the B. glabrata experimentally infected with E. cinetorchis miracidia, whereas all the Biomphalaria snails infected with E. cinetorchis cercariae were found to be infected with the metacercariae. This is the first report that B. glabrata can experimentally serve as the second intermediate host of E. cinetorchis, and that it might be employed as one of the target molluscs for establishing a biological research model with E. cinetorchis in the laboratory.

  • The availability of fast and inexpensive sequencing technology has enabled researchers around the world to conduct many genome sequencing and expressed sequence tag (EST) projects of diverse organisms. In recent years, whole genome projects have been undertaken to sequence ten species from the phylum Mollusca. These include Aplysia californica, Lottia gigantea, Crassostrea virginica, Spisula solidissima, Mytilus californianus, Biomphalaria glabrata, Crepidula fornicata, Elysia chlorotica, Lottia scutum and Radix balthica. Additionally, complete mitochondrial genomes of 91 mollusks have been reported. In Korea, EST projects have been conducted in nine mollusk species that include Nesiohelix samarangae, Pisidium (Neopisidium) coreanum, Physa acuta, Incilaria fruhstorferi, Meretrix lusoria, Ruditapes philippinarum, Nordotis gigantea, Crassostrea gigas and Laternula elliptica. Finally, the mitochondrial genome projects from the Pacific Oyster (Crassostrea gigas) and the rock shell (Thais clavigera) have been conducted and reported. However, no systemic mollusk genome project has so far been conducted in Korea. In this report, the current status and research trends in mollusk genome study in Korea will be discussed.
