Nomenclature Server

This server controls the allelic nomenclature of core genome MLST (cgMLST) bacterial gene schemes. Currently submission of new alleles and optional metadata is only possible by use of the SeqSphere+ software. A cgMLST scheme is a fixed and agreed upon number of genes for each species or group of closely related species that is ideally suited to standardize whole genome sequencing (WGS) based bacterial genotyping. By cgMLST very closely related genomes are 'lumped' together in a Complex Type (CT). In addition, this server controls the allelic nomenclature of the accessory genes of the species seed genomes.
