| Abstract | The “Spanish” influenza pandemic of 1918 was characterized by exceptionally high mortality, especially among young adults. The surface proteins of influenza viruses, hemagglutinin and neuraminidase, play important roles in virulence, host specificity, and the human immune response. The complete coding sequence of hemagglutinin was reported last year. This laboratory has now determined the complete coding sequence of the neuraminidase gene of the 1918 virus. Influenza RNA fragments were isolated from lung tissue of three victims of the 1918 flu; complete sequence was generated from A/Brevig Mission/1/18, with confirmatory sequencing carried out on A/South Carolina/1/18 and A/New York/1/18. The 1918 neuraminidase gene sequence was compared with other N1 subtype neuraminidase genes, including 9 N1 strains newly sequenced for this study. The 1918 neuraminidase shares many sequence and structural characteristics with avian strains, including the conserved active site, wild-type stalk length, glycosylation sites, and antigenic sites. Phylogenetically, the 1918 neuraminidase gene appears to be intermediate between mammals and birds, suggesting that it was introduced into mammals just before the 1918 pandemic. |

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.
