| Abstract | Pseudomonas aeruginosa is a well-known clinical pathogen for its recalcitrant infection caused by biofilm formation which are initiated by flagella-mediated attachment. Sodium houttuyfonate (SH) is a natural phytoanticipin derivative of houttuynin and has anti-pathogenic effect on P. aeruginosa biofilm formation. In this paper, when using 1/2 × MIC SH, the diameter of P. aeruginosa swimming motility was sharply shortened to 36 % in 24 h incubation, and the fold changes of fliC required for swimming motility was 0.36 in 24 h cultivation, the adherence inhibition accounted for about 46 %, and the pyocyanin production decreased to 47 % after 1-day treatment and 56 % after 3-day treatment with obvious visual changes from dark green to light green, compared with the negative control. With the help of mass spectra and scanning electronic microscope, 1/2 × MIC SH was further testified to be enough to eradicate flagella and inhibit pyocyanin secretion of P. aeruginosa. The results do not only re-affirm the close interplay of attachment and virulence (i.e. swimming motility and pyocyanin), but also unravel the potential mechanism of SH on anti-biofilm of P. aeruginosa. |

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.
