| Abstract | The marine toxic dinoflagellate Ostreopsis lenticularis has been implicated as the major vector in ciguatera seafood poisoning on the southwest coast of Puerto Rico. Studies have demonstrated that associated bacteria play a role in the ciguatoxin production and that different clonal cultures of O. lenticularis harbor different culturable bacteria. In this study, more than 125 associated bacteria from two toxic clonal cultures of O. lenticularis (no. 302 and no. 303) were analyzed utilizing polymerase chain reaction amplification of the partial small subunit ribosomal DNA (rRNA), denaturing gradient gel electrophoresis, and DNA sequencing. Approximately 50% of total bacteria identified in both cultures were a single species belonging to the Cytophaga–Flavobacter–Bacteroides complex. This bacterium was also found in six new O. lenticularis clonal cultures established 10 years after the original cultures used in this study and absent from a clonal culture of a different dinoflagellate species. The data presented here indicate a persistent and apparently specific association of this bacterium with O. lenticularis, which makes it a candidate involved in ciguatoxin production. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
