| Abstract | An understanding of the regulatory mechanisms that drive Staphylococcus aureus biofilm formation may lead to the development of an effective strategy to control the increasing number of refractory clinical infections it causes. The present study examined the effects of the antimicrobial agent human ßdefensin 3 (hBD3) and the antibiotics vancomycin and clindamycin on the expression of the S. aureus biofilm formationregulating genes, icaA and dltB, during bacterial adhesion and biofilm formation. Transcription (mRNA) levels of dlt and ica genes were measured using quantitative polymerase chain reaction, and slimes of S. aureus biofilm were examined with confocal scanning laser microscopy during S. aureus adhesion and biofilm formation. Although hBD3, vancomycin and clindamycin led to significantly attenuated biofilm formation, their treatmentassociated effects on the mRNA expression of dlt and ica were not identical. Vancomycin and clindamycin induced sustained expression of the dlt and ica genes, which may be harnessed to induce biofilm formation. However, hBD3 did not have a significant affect on the transcription level of dltB during either bacterial adhesion or biofilm formation. Therefore, the mechanism of hBD3 that regulated the suppression of biofilm formation appears to differ from the mechanisms of vancomycin and clindamycin. |

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.
