Multidrug-resistant @entity3064 is an important bacterium causing @entity580 ; @entity281 have increased in our hospital since 2009. However, multidrug-resistant A. baumannii, which was mainly isolated from @entity1 in each intensive care unit (ICU), rapidly increased from December 2012 to January 2013. Therefore, we described the molecular characteristics of A. baumannii by pulsed-field gel electrophoresis (PFGE). We also detected resistance genes for b-lactam, @entity581 , and plasmid-mediated @entity5176 . Disinfectant-resistant genes were also detected in the clinical isolates of blaOXA-51-positive multidrug-resistant A. baumannii. The conjugative test was performed to detect whether or not resistance genes can be transferred to different strains. @entity6320 ( @entity6320 ) inhibition test was conducted to analyze the factors influencing the resistance of A. baumannii to imipenem, @entity2889 , @entity5505 , @entity800 , and @entity9001 . PFGE profiles contained 12 strains, including 20 type C strains (47.6%), 4 type D strains (9.5%), and 1 to 3 strains of other types; 38 strains were distributed in @entity1 in each ICU. In our test samples, the presence of blaOXA-23 was closely related to @entity2893 resistance. The 16S rRNA methylase gene armA was associated with resistance to @entity4509 , @entity801 , and @entity2890 . The multidrug-resistant A. baumannii was closely related to various resistance genes. These results indicated that multidrug-resistant A. baumannii with type C strains was predominant in our hospital in this period.
