| Abstract | In the mid-1990s, Neoheterobothrium hirame suddenly appeared as a new species in olive flounder Paralichthys olivaceus in Japanese coastal waters. Anemia caused by the parasite has prevailed in wild and cultured populations of olive flounder since that time. In this study, to clarify the origin of N. hirame, two Neoheterobothrium species, namely unidentified Neoheterobothrium species (tentatively abbreviated as Neoheterobothrium sp. PL) and N. affine, were collected from Paralichthys lethostigma and Paralichthys dentatus, respectively, off the east coast of North America and compared with N. hirame collected in Japan. No substantial differences were detected in the morphology and DNA sequences of ITS1-5.8S rRNA-ITS2 and mitochondrial cytochrome oxidase subunit I (mt COI) regions between N. hirame and Neoheterobothrium sp. PL. On the other hand, the congeneric N. affine was clearly distinguished from both N. hirame and Neoheterobothrium sp. PL in its longer isthmus and the DNA sequences in ITS1 and mt COI. The absence of differences between N. hirame and Neoheterobothrium sp. PL and the clear difference between both of these and N. affine indicate that N. hirame is conspecific with Neoheterobothrium sp. PL infecting P. lethostigma and that N. hirame was recently introduced from North America to Japan. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
