Species

Klebsiella planticola

Description and Significance

Klebsiella planticola is a primarily environmental species, from plant and aquatic origins, that can also be isolated from clinical specimens and can be associated with various infections-- including urinary tract infections and wound infections. [2] K. planticola is a rod shaped bacterium and have been isolated from multiple environmental sources, such as the roots of wheat, corn, and rice, where they act as nitrogen-fixers. [3] They are facultative anaerobes, meaning they can survive with or without oxygen, and they are gram negative. [4]

Genome Structure

Most strains of Klebsiella planticola have one circular chromosome and four plasmids. A large number of K. planticola isolates found can have up to four antimicrobial resistant genes, which causes concern for antibiotic treatment for those infected with the bacterium. Strains have a median mega base pair count of 5.85103, 5,371 proteins, and a 55.5% GC content. [5]

Cell Structure, Metabolism and Life Cycle

Interesting features of cell structure; how it gains energy; what important molecules it produces.

K. planticola produces a polysaccharide capsule, allowing it to for large mucoid colonies as well as biofilms. [6] They are catalase producing, breaking down hydrogen peroxide to water, and ferment glucose, lactose, sorbose and the reduction of nitrates. [7]
