| Abstract | The erythromycin resistance determinant of plasmid pDB102, a derivative of plasmid pSM19035, was cloned into the single HindIII site of the 3.6-megadalton cryptic Streptococcus mutans plasmid pVA318 and introduced into Streptococcus sanguis strain Challis by transformation. Plasmid pDB201, which was isolated from one of the transformants, consisted of the vector plasmid and the 1.15-megadalton HindIII fragment D of pSM19035. HindIII fragment D contained within it one of the two unique "spacer" sequences of pSM19035. Electron micrographs of self-annealed molecules of the recombinant plasmid revealed classical stem-loop structures, and the resistance determinant of pSM19035 appeared as a transposon-like structure. No differences were observed in either the type or the level of erythromycin resistance by pSM19035 or pDB201. The availability of a cloned erythromycin resistance determinant should be useful for future comparative studies of macrolide, lincosamide, and streptogramin B resistance plasmids in streptococci. |

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.
