| Abstract | Rotter, Joan (University of Oklahoma Medical Center, Oklahoma City), and Florene C. Kelly. Serological reactions associated with the clumping factor of Staphylococcus aureus. J. Bacteriol. 91:588–594. 1966.—Evidence that the substance which causes staphylococci to clump in the presence of fibrinogen (clumping factor) is antigenically similar in strains which are serologically diverse according to agglutination reactions has been obtained from fibrinogen-cell clumping inhibition tests. Antisera for clumping factor (CF)-positive strains inhibited the clumping reaction of all strains tested. After adsorption with homologous cells or with cells of other CF-positive strains, the antisera no longer inhibited clumping. When antisera were adsorbed with trypsin-treated, CF-positive cells, or with cells of CF-negative mutants, the ability to inhibit the clumping reaction persisted. Antibody to CF activity was not associated with coagulase. Latex coated with extracts derived from the cells of five CF-positive and six CF-negative strains was, in each instance, agglutinated by sera from rabbits immunized with CF-positive cells. After adsorption with trypsinized, CF-positive cells, antisera still agglutinated latex which had been treated with the CF-positive extracts, but not with the CF-negative extracts. Similar results were obtained after antisera were adsorbed with the cells of CF-negative mutants. Cell agglutination titers of sera from rabbits immunized with CF-negative staphylococci were significantly lower than those produced in response to CF-positive cells, regardless of their coagulase activity. If the CF-inhibiting antibody also functions as an agglutinin, it apparently is not solely responsible for this difference. |

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.
