Outbreaks of carbapenem-resistant A. baumannii and A. nosocomialis have occurred worldwide in healthcare settings. Rapid and reliable molecular typing of bacterial isolates is vital for the effective surveillance of institutional outbreaks. The Pan-PCR and OXA-PCR assays are two multiplex PCR-based assays for the molecular typing of Acinetobacter species. Gap statement. However, few studies have investigated the discriminatory power of two multiplex PCR assays in in the genotyping of Acinetobacter species. Aim. We aimed to evaluate the efficacies of the Pan-PCR and OXA-PCR assays for molecular typing of A. baumannii and A. nosocomialis . Methodology. A total of 105 carbapenem-resistant A. baumannii isolates (CRABs) and 93 carbapenem-resistant A. nosocomialis isolates (CRANs) obtained from blood cultures were used for molecular typing by the Pan-PCR and OXA-PCR assays and two multilocus sequence typing (MLST) schemes. Results. The isolates were individually divided into 12 and 21 different sequence types via the Pasteur and Oxford MLST schemes, respectively. Additionally, these isolates were distinguished into 18 different types by the Pan-PCR and OXA-PCR assays. The results of the Pan-PCR and OXA-PCR assays distinguished CRABs and CRANs with a sensitivity of 98.13 % and a specificity of 100 %. Conclusion. The Pan-PCR and OXA-PCR assays are promising alternative methods for rapid molecular typing of CRABs and CRANs in a routine laboratory setting.", }
