| Abstract | Avian influenza virus H5 is a widespread virus among humans and animals which has caused fatally systemic diseases through poultry-to-person transmission in the past few years. Reverse transcription polymerase chain reaction (RT-PCR) has been proved to be an effective approach for the identification and detection of avian influenza viruses. However, conventional tube RT-PCR is slow and reagent consuming and cannot meet the need for rapid and low cost detection of pathogenic bacteria and viruses. Microfluidic PCR is a burgeoning field among the techniques based on molecular analysis. In this paper, we reported a microfluidic PCR system that integrated RT-PCR and real time fluorescence detection for rapid identification of avian influenza virus H5. This microfluidic device mainly consisted of a thermal controlling unit providing actuation for the temperature cycling needed for amplification, an optical inspection system for online recording fluorescence and a microfluidic chip fabricated using polydimethylsiloxane (PDMS). In this study, influenza virus H5 from clinical chicken throat swab specimens was rapidly detected using the RT-PCR microfluidic system, which was consistent with the results of embryonated egg culture. Compared with a large-scale device, the integrated microfluidic system presented here can perform rapid nucleic acid amplification and analysis, possibly making it a crucial platform for pathogenic bacterium and virus detection in the future. |

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.
