The Pathosystems Resource Integration Center (PATRIC) is the all-bacterial Bioinformatics Resource Center (BRC) (http://www.patricbrc.org). A joint effort by two of the original NIAID-funded BRCs[1,2], PATRIC provides researchers with an online resource that stores and integrates a variety of data types (e.g. genomics, transcriptomics, protein-protein interactions, 3D protein structures and sequence typing data) and associated metadata. Datatypes are summarized for individual genomes and across taxonomic levels. As of September 2013, there are more than 10,000 bacterial genomes available in PATRIC. All genomes in PATRIC are consistently annotated using RAST, the Rapid Annotations using Subsystems Technology[3] to facilitate comparative genomics analysis. Summaries of different data types are also provided for individual genes, as well as comparisons of different annotations. PATRIC provides a variety of ways for researchers to find data of interest and a private workspace where they can store both genome and gene groups along with their own private data. Both private and public data can be analyzed together using a suite of tools to perform comparative genomic or transcriptomic analysis. PATRIC also includes integrated information related to disease.
