  • Molluscan specimens collected in the whole country of Korea during the from 1994 through 2002, were identified and classified. A total of 1,560 molluscan species were listed in this study; one species in class Aplacophora, 18 species in class Polyplacophora, 1,038 species in class Gastropoda, 467 species in class Bivalvia, 14 species in class Scaphopoda and 22 species in class Cephalopoda. Among the identified species, 360 species (three species in class Polyplacophora, 266 species in class Gastropoda, 85 species in class Bivalvia, 6 species in class Scaphopoda) are newly recorded to Korean fauna.

  • This study was conducted to develop a proficiency test (PT) specimen for the enumeration of Escherichia coli, a sanitary indicative bacterium, in molluscan bivalve shellfish. The common mussel Mytilus edulis was chosen as a matrix for the PT specimen. Mussels were artificially bioaccumulated for approximately 3 h with E. coli culture. After determining the homogeneity of samples, samples were distributed to 17 participants involved in the proficiency testing program. The enumeration of E. coli was performed by the most probable number method of the American Public Health Association. Statistical evaluations of the results obtained from inter- and intra-laboratory variation indicated no significant differences in the accuracy of these techniques between participants, indicating z-scores of ${\leq}{\pm}2$ and suggesting that preparation of the PT specimen for enumerating E coli in shellfish was successful.
