| Abstract | We previously reported that simultaneous inoculation of mice on abraded rear footpads with two nonneuroinvasive viruses (herpes simplex virus type 1 ANG and KOS) resulted in the deaths of 62% of the animals (R. T. Javier, F. Sedarati, and J. G. Stevens, Science 234:746-748, 1986). In the current study, to better understand the events responsible for the pathogenesis of this virus mixture, we investigated replicative capacity and spread of the virus mixture within specific tissues. We found that, compared with neuroinvasiveness of ANG or KOS alone, neuroinvasiveness of the virus mixture related to significantly increased amounts of the virus within spinal cords and brains of the mice. This finding indicates that ANG and KOS have defects in their capacities to spread and replicate within spinal cords. We also examined whether the increased neuroinvasiveness of the virus mixture related to complementation between viruses in tissues of the nervous system, generation and selection of neuroinvasive recombinants, or both. It was found that, although neuroinvasive recombinant viruses could be detected in the spinal cords of the infected animals, most of the viruses (both recombinants and nonrecombinants) isolated from all tissues tested were nonneuroinvasive (i.e., no mice died as a result of footpad infection with high doses of such plaque-purified isolates). As a result of these findings, we propose that the virulence of the virus mixture is a consequence of the complementation as well as the generation and selection of neuroinvasive recombinants in spinal cords of these mice. |

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.
