Welcome to eHOMD

The goal of creating the expanded Human Oral Microbiome Database (eHOMD) is to provide the scientific community with comprehensive curated information o­n the bacterial species present in the human aerodigestive tract (ADT), which encompasses the upper digestive and upper respiratory tracts, including the oral cavity, pharynx, nasal passages, sinuses and esophagus. eHOMD should also serve well for the lower respiratory tract. Currently, eHOMD includes a total of 772 microbial species, 688 from version 14.51 of HOMD and 84 added in this expansion based o­n publicly available data o­n the microbiota of the aerodigestive tract outside of the mouth. Of all the species, 57% are officially named, 13% unnamed but cultivated and 30% are known o­nly as uncultivated phylotypes. o­ne important aspect of the eHOMD, is that it presents a provisional naming scheme for the currently unnamed taxa, based o­n the 16S rRNA sequence phylogeny, so that strain, clone and probe data from any laboratory can be directly linked to a stably named reference scheme. The eHOMD links sequence data with phenotypic, phylogenetic, clinical and bibliographic information. Genome sequences for aerodigestive tract bacteria determined as part of the HOMD project, the Human Microbiome Project and other sequencing projects are being added to the eHOMD as they become available. Genomes for 482 taxa (63% of all taxa, 89% of cultivated taxa) are currently available o­n eHOMD. The eHOMD site offers easy to use tools for viewing all publically available ADT bacterial genomes.
