The FluGenome database contains three tables: Segment, Genome and Genotype. The Segment table contains information-related to sequences, including assigned lineage, strain name, segment, serotype, host, country, year, GenBank accession number, nucleotide sequence and sequence length. The Genome table contains the information for complete genomes, including assigned genotype and accession numbers of each gene segment. When more than one sequence was available for a gene segment, the longer of the two sequences was kept for the genome accession. Unique genotypes are stored in the Genotype table along with the total number of genomes that have that genotype. The Genotype table was created by querying the Genome table for distinct genotypes. Host categories were created to separate the genomes of each genotype, which include Human (Hu), Avian (Av), Swine (Sw), Equine (Eq), Canine (Ca) and Others (ONHM).
