Enterobacter is a group (genus) of bacteria that are part of the ESKAPE pathogens. There have been 22 species that’ve been discovered so far. They are widely spread around habitats including water, soil and sewage but also have been discovered in human and animal faeces which is one reason why they have managed to inhabit so many environments. In addition, they can survive in oxygen containing (aerobic) as well as oxygen-free (anaerobic) environments.
