| Abstract | Bordetella pertussis infection is mostly diagnosed by serological tests, such as by enzyme-linked immunosorbent assays (ELISAs) or by immunoblots. We compared immunoblots from five different manufacturers. Immunoblots from Euroimmun, Mikrogen, Trinity Biotech, Viramed and Virotech were used. All kits except the kit from Trinity Biotech measured IgG and IgA antibodies separately. The kits were used according to the kit inserts. Various reference preparations from the World Health Organization (WHO), the National Institute for Biological Standards and Control (NIBSC) and the Center for Biologics Evaluation and Research/Food and Drug Administration (CBER/FDA) were analysed. Patient sera with high antibody titres in ELISA, sera from patients with compatible clinical symptoms and sera from vaccinees were compared. An algorithm for interpreting quantitative values for IgG and IgA anti-pertussis toxin (PT) from in-house ELISAs was used as a reference. The sensitivity and specificity of the assays was variable when comparing the qualitative results of immunoblots with expected values of reference preparations and ELISA interpretation of patient sera. The interpretation of semi-quantitative reading of the immunoblots did not compare well to the ELISA results. Adenylate cyclase toxin as an additional antigen in two immunoblots did not effectively distinguish between infection and vaccination. Due to the lack of quantification of antibody concentrations, IgG and IgA immunoblots are of limited value in the serological diagnosis of pertussis. |

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.
