[6] In human infections, Raoultella species are generally sensitive to treatment with carbapenems.

[7] Type species for this genus are: A phylogenetic tree of Klebsiella, based on a 2.93-Mbp alignment, unambiguously places R. ornithinolytica sister to K. oxytoca within the larger Klebsiella phylogeny and suggests abandoning the genus Raoultella designation.

[13] Robust phylogenetic analyses have repeatedly shown that species classified into this genus are nested in the genus Klebsiella, indicating Raoultella should be abandoned and considered a junior synonym of Klebsiella.

[14][15][16][17] In November 2021, the synonym Klebsiella electrica is reported "not validly published".

[18] The correct name with a valid nomenclatural status is Raoultella electrica.
