The bacterial pathogen Klebsiella pneumoniae comprises several phylogenetic groups (Kp1 to Kp7), two of which (Kp5 and Kp7) have no taxonomic status. Here we show that group Kp5 is closely related to Klebsiella variicola (Kp3), with an average nucleotide identity (ANI) of 96.4%, and that group Kp7 has an ANI of 94.7% with Kp1 (K. pneumoniae sensu stricto). Biochemical characteristics and chromosomal beta-lactamase genes also distinguish groups Kp5 and Kp7 from other Klebsiella taxa. We propose the names Klebsiella africanensis for Kp7 (type strain, 200023T = CIP 111653T) and K. variicola subsp. tropicalensis for Kp5 (type strain, 1266T = CIP 111654T).

细菌性病原体肺炎克雷伯菌包括几个系统发育群（Kp1至Kp7），其中两个（Kp5和Kp7）没有分类学地位。在这里，我们显示Kp5组与水痘克雷伯菌（Klebsiella variicola）（Kp3）密切相关，平均核苷酸同一性（ANI）为96.4％，而Kp7组与Kp1（K. pneumoniae sensu stricto）的ANI为94.7％。生化特征和染色体β-内酰胺酶基因还将Kp5和Kp7组与其他克雷伯菌分类群区分开。我们为Kp7（类型菌株，200023T = CIP 111653T）和水痘克雷伯菌亚种命名为非洲克雷伯菌。用于Kp5的tropicalensis（类型菌株，1266T = CIP 111654T）。
