The mechanisms that induce codon biases remain an open question; studies have attributed codon usage to translational selection, mutational bias and drift. Furthermore, correlations between codon usage within host genomes and their viral pathogens have been observed for a myriad of host-virus systems. As such, numerous studies have investigated codon usage and codon bias in an effort to better understand how species evolve. Numerous metrics have been developed to identify biases in codon usage. In addition, a few data repositories of codon bias data are available, differing in the metrics reported as well as the number and taxonomy of strains examined.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Description<\/jats:title>\n            <jats:p>We have created a new web resource called the Codon Bias Database (CBDB) which provides information regarding the codon bias within the set of highly expressed genes for 300+ bacterial genomes. CBDB was developed to provide a resource for researchers investigating codon bias in bacteria, facilitating comparisons between strains and species. Furthermore, the site was created to serve those studying adaptation in phage; the genera selected for this first release of CBDB all have sequenced, annotated bacteriophages. The annotations and sequences for the highly expressed gene set are available for each strain in addition to the strain\u2019s codon bias measurements.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>Comparing species and strains provides a comprehensive look at how codon usage has been shaped over evolutionary time and can elucidate the putative mechanisms behind it. The Codon Bias Database provides a centralized repository of look-up tables and codon usage bias measures for a wide variety of genera, species and strains. Through our analysis of the variation in codon usage within the strains presently available, we find that most members of a genus have a codon composition most similar to other members of its genus, although not necessarily other members of its species.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/1471-2105-13-62","type":"journal-article","created":{"date-parts":[[2012,4,26]],"date-time":"2012-04-26T12:14:29Z","timestamp":1335442469000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["CBDB: The codon bias database"],"prefix":"10.1186","volume":"13","author":[{"given":"Adam","family":"Hilterbrand","sequence":"first","affiliation":[]},{"given":"Joseph","family":"Saelens","sequence":"additional","affiliation":[]},{"given":"Catherine","family":"Putonti","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2012,4,26]]},"reference":[{"key":"5381_CR1","first-page":"95","volume":"34","author":"N Sueoka","year":"1962","unstructured":"Sueoka N: On the genetic basis of variation and heterogeneity of DNA base composition.
