Eight representative outbreak isolates were investigated in detail. Fermentation characteristics, biochemical assays and fatty acid profiles for taxonomic analysis were determined and supplemented with information derived from whole genome sequences. Phenotypic and morphological tests revealed that these isolates were Gram-stain-negative, rod-shaped, highly motile and facultatively anaerobic. The fatty acid profile was similar to those of the type strains for all recognized Enterobacter species, with quantitative differences in C17 : 0, C18 : 1ω7c and C17 : 0 cyclo fatty acids. Whole genome sequencing was used to identify taxonomically relevant characteristics, i.e. for 16S rRNA gene sequence analysis, multi-locus sequence analysis (MLSA), in silico DNA–DNA hybridization (isDDH) and average nucleotide identity (ANI). Draft genomes were approximately 4.9 Mb in size with a G+C content of 56.0 mol%. The 16S rRNA gene sequence of these eight isolates showed >97 % similarity to all Enterobacter species, while MLSA clustered them closely with the type strains of Enterobacter xiangfangensis and Enterobacter hormaechei. These eight strains showed less than 70 % isDDH identity with the type strains of Enterobacter species. In addition, less than 95 % ANI to the type strains of Enterobacter species was observed. From these results, it is concluded that these isolates possess sufficient characteristics to differentiate them from all recognized Enterobacter species, and should therefore be considered as representing a novel species. The name Enterobacter bugandensis sp. nov. is proposed with EB-247T ( = DSM 29888T = NCCB 100573T) as the type strain., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.000821
