Enterobacter aerogenes and E. cloacae

Gram stain:  negative
Cell shape:  bacillus
Arrangement:  single
Oxygen requirements:  facultative anaerobes

Habitat:  intestinal tracts of humans and animals; water; sewage; soil

Pathogenicity:  Commonly called "enterics", they can cause urinary tract infections and nocosomial infections. Their presence is not indicative of fecal contamination, so we run a test called the IMViC test to distinguish them from another member of this family, E. coli. Both of these organisms are used here in our labs.
