| Abstract | Brucellosis is a worldwide zoonotic disease. No Brucella vaccine is available for use in humans, and existing animal vaccines have limitations. There is a need to develop a safe and effective vaccine against human and animal brucellosis. In the present study, we generated recombinant cysteine synthase A (rCysK) of Brucella abortus in Escherichia coli and purified it up to homogeneity by metal affinity chromatography. The immunogenicity and protective efficacy of purified rCysK were evaluated in BALB/c mice with Freund’s adjuvant, aluminium hydroxide gel or without any adjuvant. High titres of anti-rCysK IgG antibody predominated by IgG1 were observed in all immunized mice. After stimulation with rCysK, the spleen lymphocytes of mice immunized with CysK formulated with aluminium hydroxide gel produced significant levels of IFN-γ. Protection against challenge with virulent B. abortus strain 544 was determined in BALB/c mice, and significant protection was observed in all CysK immunized groups when compared with PBS control. Among all the CysK vaccine groups, comparatively better protection was observed in mice immunized with aluminium hydroxide gel (1.064 units of protection). Overall, the results of the study suggest that rCysK induces primarily Th2 type of immune response and provides partial protection against B. abortus challenge. |

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.
