Comparison to type strains is mandatory for any methodological approach as it is the only strain which is available from public resource centers for comparative purposes while for the vast majority of strains the gene sequence accession number but not the strain itself is available. The recent release of the All-species Living Tree Project (LTP) (www.imedea.uib-csic.es/mmg/ltp, Ludwig et al. [[3]]) contains more than 17.500 curated complete or almost complete 16S rRNA gene sequences of archaeal and bacterial type strains (indicating that such sequences are available for comparison of > 80% of the type strains). As the intra-species variability in phenotypic and genomic differences among strains is often wide, the type strain - and not the species/strain name with the highest similarity, e.g. BLAST score - is the most important one to be used. A type strain is the strain on which the description is based, the name bearing strain, hence the point of reference [[4]], Parker et al. [[1]]). [Extracted from the article]
