| Abstract | Pigs suckling dams that have been vaccinated with pilus antigen are protected against challenge with enterotoxigenic Escherichia coli (ETEC) strains that express the same pilus antigen. However, some ETEC strains express more than one pilus antigen. Pregnant swine were vaccinated either with E. coli HB101 that harbored a recombinant plasmid coding for F41 expression (F41+) or with the HB101 parent strain that carries the pHC79 vector (F41-). Suckling pigs born to vaccinated dams were challenged with ETEC that expressed either K99, F41, or both pilus antigens. Production of F41 in vivo was demonstrated by immunofluorescence assay of sections of ileum and by seroconversion against F41 antigen by pigs challenged with F41+ and K99+ F41+ ETEC strains. The F41+ vaccine protected against challenge with an F41+ ETEC strain. In contrast, F41+ vaccination did not protect against challenge with K99+ or K99+ F41+ ETEC strains. The F41- vaccine did not protect against challenge with any strain used. The results indicate that K99+ F41+ ETEC strains produce F41 antigen in the small intestine during disease and that F41+ vaccination can be a protective antigen if the challenge strain expresses only F41 antigen, but that F41+ vaccination may not protect against strains that produce both K99 and F41 antigens. |

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.
