| Abstract | Avian influenza has been regarded as a human health threat. A major measure to prevent its outbreak is vaccination. In this study, a series of expression plasmids carrying the hemagglutinin (HA), neuraminidase (NA), nucleoprotein (NP), matrix protein 1 (M1), and matrix protein 2 (M2) genes, respectively, of the avian influenza virus (AIV) A/Chicken/Henan/12/2004(H5N1) strain were constructed. These plasmids were administered to mice by electroporation (50 μg for each per administration, 1–5 times, at an interval of 2 weeks), and the mice were challenged with the homologous virus later. The mice immunized with HA plasmid once and the NA plasmid twice survived 100%, and those with NP plasmid showed 60–80% survival rate with at least three immunizations. The mice immunized with M1 plasmid survived 25% with five immunizations, while M2 plasmid had no protection even with five immunizations. The mixture of M1 and NP plasmids protected 95% of the mice against the homologous virus, and 80% of the mice against a challenge with heterologous H1N1 (PR8) virus. Moreover, the homologous protection lasted at least 6 months. Our data provided a basis for selecting multiple-component AIV vaccines. |

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.
