| Outline of Final Research Achievements |
Acinetobacter baumannii is generally the most frequently isolated Acinetobacter species. According to a recent report from Norway, Acinetobacter nosocomialis was the most frequent isolate from blood cultures. Since the biochemical characteristics of different Acinetobacter spp. are almost identical, accurate identification at the species level is difficult with routine laboratory methods.There is the possibility of different clinical outcomes due to infection with different genospecies since a difference in antibiotic susceptibility between A. baumannii and non-A. baumannii has been reported.The isolates included A. soli (13, 27.1%), A. nosocomialis (12, 25%), A. baumannii (9, 18.8%), A. ursingii (8, 16.7%), A. pittii (3, 6.3%), A. genomic species "close to 13TU (1, 2.1%), A. junii (1, 2.1%) and A. guillouniae (1, 2.1%). Accordingly, our findings emphasize the importance of performing further epidemiological investigation of Acinetobacter species.
