Escherichia hermannii

Escherichia hermannii is a Gram-negative, rod-shaped species of bacterium. Strains of this species were originally isolated from human wounds, sputum, and stool. The species is named for American microbiologists George J. Hermann and Lloyd G. Herman.[1]

Escherichia hermannii
Scientific classification
Domain: Bacteria
Phylum: Pseudomonadota
Class: Gammaproteobacteria
Order: Enterobacterales
Family: Enterobacteriaceae
Genus: Escherichia
Species:
E. hermannii
Binomial name
Escherichia hermannii
Brenner et al. 1983

A 2016 publication proposed reclassifying E. hermannii as a species of a new genus within the Enterobacteriaceae, Atlantibacter, a change which would rename the species to Atlantibacter hermannii.[2]

Pathogenicity

E. hermannii is generally considered nonpathogenic but has been isolated from human wounds,[3] eye infections,[4][5] and blood.[6][7][8]
