We previously developed the Transposon Directed Insertion Sequencing (TraDIS) protocol for this purpose, which utilizes shearing of genomic DNA followed by specific PCR amplification of transposon-containing fragments and Illumina sequencing. Here we describe an optimized high-yield library preparation and sequencing protocol for TraDIS experiments and a novel software pipeline for analysis of the resulting data. The Bio-Tradis analysis pipeline is implemented as an extensible Perl library which can either be used as is, or as a basis for the development of more advanced analysis tools. This article can serve as a general reference for the application of the TraDIS methodology.}, language = {en} } @article{HarrisonClausJiangetal.2013, author = {Harrison, Odile B. and Claus, Heike and Jiang, Ying and Bennett, Julia S. and Bratcher, Holly B. and Jolley, Keith A. and Corton, Craig and Care, Rory and Poolman, Jan T. and Zollinger, Wendell D. and Frasch, Carl E. and Stephens, David S. and Feavers, Ian and Frosch, Matthias and Parkhill, Julian and Vogel, Ulrich and Quail, Michael A. and Bentley, Stephen D. and Maiden, Martin C.

Thirteen capsular polysaccharides have been described, and nuclear magnetic resonance spectroscopy has enabled determination of the structure of capsular polysaccharides responsible for serogroup specificity. Molecular mechanisms involved in N. meningitidis capsule biosynthesis have also been identified, and genes involved in this process and in cell surface translocation are clustered at a single chromosomal locus termed cps. The use of multiple names for some of the genes involved in capsule synthesis, combined with the need for rapid diagnosis of serogroups commonly associated with invasive meningococcal disease, prompted a requirement for a consistent approach to the nomenclature of capsule genes. In this report, a comprehensive description of all N. meningitidis serogroups is provided, along with a proposed nomenclature, which was presented at the 2012 XVIIIth International Pathogenic Neisseria Conference.}, language = {en} }
