Transfer of 13 species of the genus Burkholderia to the genus Caballeronia and reclassification of Burkholderia jirisanensis as Paraburkholderia jirisanensis comb. nov

A recent study of a group of Burkholderia glathei -like bacteria resulted in the description of 13 novel species of the genus Burkholderia . However, our analysis of phylogenetic positions of these species and their molecular signatures (conserved protein sequence indels) showed that they belong to the genus Caballeronia , and we propose to transfer them to this genus. The reclassified species names are proposed as Caballeronia arationis comb. nov., Caballeronia arvi comb. nov., Caballeronia calidae comb. nov., Caballeronia catudaia comb. nov., Caballeronia concitans comb. nov., Caballeronia fortuita comb. nov., Caballeronia glebae comb. nov., Caballeronia hypogeia comb. nov., Caballeronia pedi comb. nov., Caballeronia peredens comb. nov., Caballeronia ptereochthonis comb. nov., Caballeronia temeraria comb. nov. and Caballeronia turbans comb. nov. It is also proposed to reclassify Burkholderia jirisanensis as Paraburkholderia jirisanensis comb. nov. Based on the results of the polyphasic study, B. jirisanensis had been described as a member of the A-group of the genus Burkholderia and the most closely related to Burkholderia rhizosphaerae , Burkholderia humisilvae and Burkholderia solisilvae currently classified as belonging to the genus Paraburkholderia .
