Next generation sequencing (NGS) data from whole pathogen genomes is frequently used for enhanced surveillance and outbreak detection of common pathogens. CLC Microbial Genomics Module introduces functionality for molecular typing and epidemiological analysis of bacterial isolates. The module enables the user to perform a range of analyses, or to take advantage of template workflows for routine surveillance or outbreak analysis of a specific pathogen (figure 9.1).
The typing and epidemiology features include streamlined tools for NGS-based Multilocus Sequence Typing (MLST) and resistance typing, as well as fast detection of genus and species. It also includes tools for phylogenetic tree reconstruction based on single nucleotide polymorphisms (SNPs) or inference of K-mer trees from NGS reads or genomes. A new table format, acting as a database, collects typing results and associates these with metadata such as sample information, geographic origin, treatment outcome, etc. Results generated using NGS-MLST and resistance typing can hereby be associated with the original sample metadata. Users can filter on analysis results and metadata and then select relevant subsets of samples for downstream analysis. Results and metadata available during tree generation can also be used to explore and decorate this epidemiologically relevant information on the phylogenetic tree.
The Typing and Epidemiology tools are described in the following chapters.
