Abstract:

Objective

To investigate the molecular epidemiological characteristics of carbapenem-resistant Acinetobacter baumannii (CRAB) isolated from our hospital at a certain time, and to provide the basis for the prevention and control of nosocomial infections.

Methods

Total of 55 stains of CRAB were isolated from the hospital from October 2015 to February 2016. Cloning relationship were conducted by multi-site sequence typing (MLST). The screening of carbapenemase gene and disinfectant gene (qacEΔ1) were detected by PCR.

Results

Six kinds of STs were detected by MLST, which were ST208 (38.2%), ST369 (25.5%), ST195 (20%), ST451 (10.9%), ST195 (3.6%) and ST381 (1.8%). Carbapenemase genes, such as OXA-51 and OXA-23 were both positive, and 96.4% (53/55) of the stains carried qacEΔ1 gene. More than 90% of the specimens were isolated from sputum separated from the patients in Intensive Care Unit.

Conclusions

There was a prevalence caused by CRAB stains of clones during this period. ST208, ST369 and ST195 CRAB carrying OXA-23 gene were the main clones in our hospital.
