EbolaID (http://ebolaid.portugene.com) provides a complete, quality checked and regularly updated list of oligonucleotides for the Ebola virus. The database describes the genetic diversity across the Ebola genome to facilitate the design of accurate diagnostic methods and therapeutic approaches. The database provides an interface for browsing, filtering, and downloading data from published oligonucleotide sequences (PCR primers, real-time PCR probes, etc.) annotated according to a reference genome. The user can find varied information for each oligonucleotide: the type of technique where it was originally used, the sequence, location in the reference genome, references, etc. The database provides different measures of sequence conservation for each target region obtained from multiple sequence alignments, allowing the selection of the most conserved oligonucleotides.
