Prevotella sp. oral taxon 299 strain F0039 has been isolated from a human subject by the Moore's Laboratory in September 1981. The subject was a 44 years old American white male. The bacteria was isolated from the subgingival oral biofilm at an healthy site. The partial 16S ribosomal RNA gene was deposited to GenBank under the reference FJ577257. The strain is available at www.bei.org under the reference HM-3. This strain is now part of the reference strains for the oral section of the Human Microbiome Project.
