Acinetobacter baumannii&160received very little attention until the 1990s. Since its low virulence, it was not considered as a pathogenic bacteria. During the 21st&160century, the infection rate had been increasing for patients with weak immunity, especially in the intensive care units. This bacterium was also of great concern due to its strong antibiotics resistance. Although colistin had not been used because of its nephrotoxicity, it has been reintroduced to treat multi-drug resistant Gram-negative pathogens, including A.&160baumannii. Due to its unfamiliarity for some time, the antibiotic resistance of colistin was relatively low however, recent reports have shown that the resistance rate has been steadily rising. The research on colistin resistance and its resistance mechanism is actively being conducted and several genes associated with the resistance have been discovered. Then, we proved the resistance gene candidates by comparing the whole transcriptome between colistin-susceptible and &8211resistant A.&160baumannii&160strains with further analyses.
