| Abstract | Antimicrobials are used as feed additives to improve growth performance and to prevent subclinical disease challenge in industrial animals. However, these drugs can lead to the development of resistant strains of bacteria. Shiitake mushrooms (SM) (Lentinula edodes) have long been popular as a health food in East Asia. Moreover, SM-derived polysaccharides are well-known as immunostimulants that possess antimicrobial properties. The aim of the present study was to evaluate the immunoprophylactic effects of SM against Bordetella bronchiseptica infection in mice as an initial step towards the development of eco-friendly feed additives to reduce the use of antimicrobials. Although SM had no effect on body weight gain under the un-infected conditions, SM alleviated progressive weight loss and helped in the recovery of body weight in B. bronchiseptica infected mice. Dietary supplementation with SM reinforced bacterial clearance in the infected mice. Of note, SM markedly increased the percentage of various T lymphocytes and the relative mRNA expression levels of tumor necrosis factor-α and interferon-γ in the bronchial lymph node early in the infection. Taken together, these findings suggest that SM could help in the improvement of body weight gain during B. bronchiseptica infection and may enhance the protective immune activity against a subclinical disease challenge, such as B. bronchiseptica infection in mice, probably by a strong stimulation of non-specific immune responses. Hence, SM may provide an alternative to reduce use of antimicrobials. Confirmation of the beneficial effects of SM as a feed additive is now required in industrial animals. |

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.
