Abstract:
Objective To investigate the distribution and antimicrobial resistance profile of clinical gram-negative bacterial isolates in the First Afifliated Hospital of Nanjing Medical University during 2014.Methods Bacteria identiifcation was performed by API system or the VITEK-2 Compact automatic identiifcation system. Disk diffusion susceptibility testing or VITEK-2 Compact automatic identification system was used to determine the susceptibility to antimicrobial agents. All data were analyzed using WHONET 5.6 software.Results Among the total 7 931 clinical isolates in 2014, gram-negative bacteria accounted for 64.2% (5 088/7 931). The top three pathogens wereE. coli,A. baumannii andK. pneumoniae. Notably, during the year 2014, 195 strains of carbapenem-resistantEnterobacteriaceaewere isolated, about 6.9% of all theEnterobacteriaceae isolates. Meanwhile, 613 (66.5%) strains of multiple drug resistantA. baumannii and 197 (28.7%) strains of multiple drug resistantP. aeruginosa were isolated.Conclusion During the year 2014, the resistance of the gram-negative bacteria in this hospital is mainly characterized by carbapenem-resistantEnterobacteriaceae, multiple drug resistant A. baumanniiand multiple drug resistantP. aeruginosa. Surveillance of antimicrobial resistance is beneifcial for rational use of antibiotics.
