Huang H, et al. - In intensive care unit inpatients, researchers explored the risk factors, epidemiological characteristics, and resistance of multidrug-resistant Acinetobacter baumannii (MDR-AB). In this study, mechanical ventilation, combined using antibiotic before isolation of AB, and indwelling catheter were observed to be correlated with MDR-AB infection. In addition, they found that the age and the days of mechanical ventilation were associated with increased MDR-AB infection.
