Klebsiella terrigena is a Gram-negative bacterial species of the genus Klebsiella. It has primarily been isolated from soil and water samples,[1] but rarely from humans. Studies have estimated fewer than 1% of healthy people harbor this species.[2] This species has shown no connection with disease in humans despite expressing many of the virulence factors expressed by other Klebsiella species such as Klebsiella pneumoniae.[3]
Phylogenic comparisons between the 16s rRNA and rpoB genes of this and other Klebsiella species have suggested classification into a newer genus, Raoultella.[4]
K. terrigena is considered a factor in melamine toxicity. In culture, K. terrigena was shown to convert melamine to cyanuric acid directly. Rats colonized by K. terrigena showed greater melamine-induced kidney damage compared to those not colonized.[5]
