| Abstract | Anacker, R. L. (Rocky Mountain Laboratory, Hamilton, Mont.), W. D. Bickel, W. T. Haskins, K. C. Milner, E. Ribi, and J. A. Rudbach. Frequency of occurrence of native hapten among enterobacterial species. J. Bacteriol. 91:1427–1433. 1966.—Smooth cultures of representative Enterobacteriaceae were screened for the presence of native hapten, a substance previously extracted with trichloroacetic acid from the protoplasmic fraction of one strain each of Escherichia coli O111:B4 and O113. Trichloroacetic acid extracts of protoplasmic fractions of the cells were analyzed for chemical composition, for constituent sugars by paper chromatography, for immunochemical relationship to endotoxin purified by gel filtration, for sedimentation behavior, and for pyrogenicity in rabbits and lethal toxicity in chick embryos. Extracts from two of three additional strains of E. coli O113, all five additional strains of E. coli O111:B4, and one strain each of E. coli O26:B6 and O55:B5 were similar to previously described native hapten in chemical composition, sedimentation properties (S 20,w, 3.7 to 5.2), biological potency (usually less than 0.1% that of corresponding endotoxin), and immunochemical relationship to endotoxin. Extracts of one strain each of E. coli O127:B8, Serratia marcescens, Citrobacter freundii, Salmonella enteritidis, and of two lipopolysaccharide-deficient mutants of S. enteritidis differed from typical native hapten. The biosynthetic relationship of native hapten to endotoxin has not yet been revealed. |

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.
