Burkholderia orbicola sp. nov., a novel species within the Burkholderia cepacia complex

Genome analysis of strains placed in the NCBI genome database as Burkholderia cenocepacia defined nine genomic species groups. The largest group (259 strains) correspond s to B. cenocepacia and the second largest group (58 strains) was identified as “ Burkholderia servocepacia” , a Burkholderia species classification which has not been validly published. The publication of “ B. servocepacia” did not comply with Rule 27 and Recommendation 30 from the International Code of Nomenclature of Prokaryotes (ICNP) and have errors in the type strain name and the protologue describing the novel species. Here, we correct the position of this species by showing essential information that meets the criteria defined by ICNP. After additional analysis complying with taxonomic criteria, we propose that the invalid “ B. servocepacia” be renamed as Burkholderia orbicola sp. nov. The original study proposing “ B. servocepacia ” was misleading, because this name derives from the Latin “servo” meaning “to protect/watch over”, and the authors proposed this based on the beneficial biocontrol properties of several strains within the group. However, it is clear that “ B. servocepacia ” isolates are capable of opportunistic infection, and the proposed name Burkholderia orbicola sp. nov. takes into account these diverse phenotypic traits. The type strain is TAtl-371 T (= LMG 30279 T = CM-CNRG 715 T ).
