Klebsiella variicola

Klebsiella variicola is a species of bacteria which was originally identified as a benign endosymbiont in plants, but has since been associated with disease in humans and cattle as well.

Description

Klebsiella variicola was described as a species of Klebsiella distinct from its closely related species Klebsiella pneumoniae in 2004.[1] Like other Klebsiella species, K. variicola is gram-negative, rod-shaped, non-motile, and covered by a polysaccharide capsule.

Hosts

Klebsiella variicola is known to associate with a number of different plants including banana trees,[1] sugarcane[2] and has been isolated from the fungal gardens of leaf-cutter ants.[3][4] Some K. variicola strains have been associated with disease in humans, suggesting they may be able to serve as opportunistic pathogens of humans.[5][6] K. variicola have also been isolated from cows suffering from bovine mastitis.[7][8]
