Remarks: |
16S rDNA sequence analysis was performed on the type strains of all validly described Acinetobacter species and five unnamed Acinetobacter strains. The phylogenetic analyses confirm that Acinetobacter is a coherent genus within the gamma subclass of Proteobacteria and that the species are phylogenetically well defined. A. calcoaceticus, A. lwoffii, A. johnsonii and A. haemolyticus form one cluster of closely related species, the pair A. junii and A. baumannii forms a second cluster. A. radioresistens stands phylogenetically isolated. The study reveals that three undescribed strains can be assigned to individually described species, while strains DSM 30009 and DSM 590 may represent two novel Acinetobacter species. |

Remarks: |
Partial nucleotide sequences of the gyrB genes (DNA gyrase B subunit genes) of 15 Acinetobacter strains, including the type and reference strains of genomic species 1 to 12 (A. calcoaceticus [genomic species 1], A. baumannii [genomic species 2], Acinetobacter genomic species 3, A. haemolyticus [genomic species 4], A. junii [genomic species 5], Acinetobacter genomic species 6, A. johnsonii [genomic species 7], A. lwoffii [genomic species 8], Acinetobacter genomic species 9, Acinetobacter genomic species 10, Acinetobacter genomic species 11, and A. radioresistens [genomic species 12]), were determined by sequencing the PCR-amplified fragments of gyrB. The gyrB sequence homology among these Acinetobacter strains ranged from 69.6 to 99.7%. A phylogenetic analysis, using the gyrB sequences, indicates that genomic species 1, 2, and 3 formed one cluster (87.3 to 90.3% identity), while genomic species 8 and 9 formed another cluster (99.7% identity). These results are consistent with those of DNA-DNA hybridization and of biochemical systematics. On the other hand, the topology of the published phylogenetic tree based on the 16S rRNA sequences of the Acinetobacter strains was quite different from that of the gyrB-based tree. The numbers of substitution in the 16S rRNA gene sequences were not high enough to construct a reliable phylogenetic tree. The gyrB-based analysis indicates that the genus Acinetobacter is highly diverse and that a reclassification of this genus would be required. |

Remarks: |
The phylogenetic relationships of 49 Acinetobacter strains, 46 of which have previously been classified into 18 genomic species by DNA-DNA hybridization studies, were investigated using the nucleotide sequence of gyrB, the structural gene for the DNA gyrase B subunit. The phylogenetic tree showed linkages between genomic species 1 (Acinetobacter calcoaceticus), 2 (Acinetobacter baumannii), 3 and TU13; genomic species 6, BJ15, BJ16 and BJ17; genomic species 5, BJ13 (synonym of TU14) and BJ14; genomic species 7 (Acinetobacter johnsonii), 10 and 11; and genomic species 8 and 9. The phylogenetic grouping of Acinetobacter strains based on gyrB genes was almost congruent with that based on DNA-DNA hybridization studies. Consequently, gyrB sequence comparison can be used to resolve the taxonomic positions of bacterial strains at the level of genomic species. However, minor discrepancies existed in the grouping of strains of genomic species 8, 9 and BJ17. The phylogenetic tree for these strains was reconstructed from the sequence of rpoD, the structural gene for the RNA polymerase sigma 70 factor. The latter tree was 100% congruent with the grouping based on DNA-DNA hybridization. The reliability of DNA-DNA hybridization may be superior to that of sequence comparison of a single protein-encoding gene in resolving closely related organisms since the former method measures the homologies between the nucleotide sequences of total genomic DNAs. Three strains that have not been characterized previously by DNA-DNA hybridization seem to belong to two new genomic species, one including strain ATCC 33308 and the other including strains ATCC 31012 and MBIC 1332. |
