AI Article Synopsis
- 114 Acinetobacter sp. isolates were collected from emergency departments in two Korean hospitals, with 92.1% belonging to the Acinetobacter baumannii complex.
- Imipenem resistance was observed in 34.2% of the isolates, with additional cases of colistin resistance, highlighting significant antimicrobial resistance issues.
- Species distribution varied between hospitals, with distinct genetic profiles found in imipenem-resistant isolates, emphasizing the need for ongoing monitoring of these bacteria in healthcare settings.
Article Abstract
A total of 114 Acinetobacter sp. isolates were collected from patients in the emergency departments (EDs) of two Korean hospitals. Most isolates belonged to the Acinetobacter baumannii complex (105 isolates, 92.1 %). Imipenem resistance was found in 39 isolates (34.2 %) of the Acinetobacter sp. isolates, and 6 colistin-resistant isolates were also identified. Species distribution and antimicrobial-resistance rates were different between the two hospitals. In addition, two main clones were identified in the imipenem-resistant A. baumannii isolates from hospital B, but very diverse and novel genotypes were found in those from hospital A. Many Acinetobacter sp. isolates, including the imipenem-resistant A. baumannii, are considered to be associated with the community. The evidence of high antimicrobial resistance and different features in these Acinetobacter sp. isolates between the two EDs suggests the need for continuous testing to monitor changes in epidemiology.
