| Abstract | Brucella melitensis native haptens (NH) are polysaccharides identical to the O-side chain of the smooth lipopolysaccharide (S-LPS) (E. Moreno, H. Mayer, and I. Moriyón, Infect. Immun. 55:2850-2853, 1987) which precipitate with sera from infected cattle but not from strain 19-vaccinated cattle. In the present work, NH was extracted by the hot-water method (R. Díaz, J. Toyos, M.D. Salvo, and M.L. Pardo, Ann. Rech. Vet. 12:35-39, 1981) and purified free of S-LPS and protein. Purified NH lacked the ability to coat polystyrene and sheep erythrocytes. In contrast, NH acylated with stearoyl chloride bound to both polystyrene and erythrocytes. By hemagglutination and enzyme-linked immunosorbent assay (ELISA), S-LPS and acylated NH gave similar results with blood sera from brucellosis-free, strain 19-vaccinated, and infected cattle. Moreover, a significant correlation between the results of NH ELISA and S-LPS ELISA was demonstrated with milk sera. However, in a competitive ELISA with milk sera, S-LPS in the liquid phase abrogated the binding of antibodies to acylated NH adsorbed to polystyrene, while NH in the liquid phase did not influence the binding of antibodies to polystyrene-adsorbed S-LPS. It is hypothesized that the different precipitations of NH and S-LPS with sera from infected or strain 19-vaccinated cattle are due to differences in the affinity of the antibodies produced upon vaccination or infection and in the physical state of aggregation of NH and S-LPS in aqueous solutions. |

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.
