Yokenella Explained

Yokenella is a genus of bacteria of the family Enterobacteriaceae. Yokenella are Gram-negative, motile, rod-shaped bacteria. Strains of bacteria forming this genus were originally isolated from clinical samples, from the boxelder bug,[1] and from alligators.[2]

There is only one species in this genus: Yokenella regensburgei.[3]

Yokenella is not an important pathogen, but it has been found in sporadic cases of finger osteitis,[4] necrotizing fasciitis,[5] in urinary tract infections,[6] and a few other diseases, some of which may have been caused by immunosupression.[7]

A draft genome sequence is 5,277,883 bp in size and has 5,416 genes.[8] The genome is thus larger than average bacterial genomes, such as Escherichia coli whose genome is about 4 MB in size.
