Next generation sequencing (NGS) technology allows for not only rapid detection and identification<br />
of pathogens from a variety of sample types, but also rapid genetic characterization. Rapid characterization<br />
of pathogenic bacteria and their virulence factors from an isolate or a metagenomic sample<br />
is critical for threat detection and biodefense. A key component to virulence factors identification<br />
is a well curated database. With new virulence factors being discovered on a regular basis it is<br />
necessary to use the most up to date and well documented database possible. The EDGE Bioinformatic<br />
software package represents a collaborative effort between Los Alamos National Laboratory<br />
and Naval Medical Research Center to provide a user‐friendly bioinformatic software package that<br />
enables rapid NGS data analysis, even when resources are limited. To support the development<br />
of a virulence factor identification module in EDGE, we have performed comparisons of the existing<br />
virulence factors databases (VFDB, PATRIC_VF, MvirDB, and Victors) to determine which<br />
databases are most up‐to‐date, most accurate and inclusive, and contain useful metadata about the<br />
virulence factors. We have condensed two databases, VFDB and PATRIC_VF, into one database,<br />
removing redundant entries at the strain level. This database will be used by a new module in<br />
the EDGE Bioinformatics software platform to annotate called genes as virulence factors within an<br />
isolate. With the use of software like ShortBRED the database will also be used to generate a profile<br />
of the virulence factors that are detected in a metagenomic sample. In an alternative approach, this<br />
database will also be used with the STRING protein‐protein network database as input for a novel<br />
bioinformatic approach to determine the probability of sample virulence.<br />
