A DNA-DNA hybridization study was carried out to determine the taxonomic position of a new group of enterobacters (group H3, Gavini, et al.) previously studied by numerical taxonomy. The reassociation binding ratios with the group H3 strain, ATCC 33072, ranged from 61-97%. With respect to DNA hybridization, this group, which represents a new species in the genus Enterobacter, E. amnigenus, is closely related (49-66%) to E. cloacae. A difference in genome size between E. amnigenus ATCC 33072 and E. cloacae Collection de l'Unite d'Ecotoxicologie Microbienne (CUETM) 77-120 was observed after reciprocal binding: the genome of ATCC 33072 was 24% larger. E. amnigenus was defined from phenotypic and genetic data. The type strain of E. amnigenus is CUETM 77-118 (ATCC 33072).
