The taxonomic position of Klebsiella alba was re-examined. The reconstructed phylogenetic tree based on multilocus sequence analysis showed that Klebsiella alba LMG 24441 (=KCTC 12878) was closely related to Klebsiella quasipneumoniae subsp. similipneumoniae 07A044, showing 99.5–100 % similarities for fusA, gapA, gyrA, leuS, pyrG, rpoB, rpoB2, atpD, gyrB and infB gene sequences and concatenated partial fusA, gapA, gyrA, leuS, pyrG, rpoB2, atpD, gyrB and infB gene sequences. High sequence similarities between Klebsiella alba LMG 24441 and Klebsiella quasipneumoniae subsp. similipneumoniae 07A044 indicated that they have the same taxonomic position. Klebsiella alba was reclassified as Klebsiella quasipneumoniae subsp. similipneumoniae and Klebsiella alba is a later heterotypic synonym of Klebsiella quasipneumoniae subsp. similipneumoniae .
