Resistance Analysis of 49 Strains of Acinetobacter Baumannii

Objective:To analysis resistance of 49 strains of acinetobacter baumannii for clinical control and treatment of acinetobacter baumannii provides the basis.Methods:From January 2010 to January 2011,specimens of secretions,cerebrospinal fluid,lung lavage fluid,sputum,purulent fluid in hospitalized patients were separated out of acinetobacter baumannii 49 strains,used VITEK-2 system to identify bacteria;Drug sensitive test was conducted by antibiotics drug diffusion method;acinetobacter baumannii resistance was analyzed by WHONET 5.4 analysis software.Results:Acinetobacter baumannii resistance had the grim situation,the separating and resistant rate were increasing year by year,and multiple resistance and the resistance ratio increased significantly.Resistance of seven clinical common antibiotic was tested in 49 strain of acinetobacter baumannii,the antibiotic resistance rate of gentamycin,meropenem,cefepime,ceftazidime,cefotaxime,ciprofloxacin,amikacin were 53.06%,32.65%,22.45%,32.65%,44.90%,30.61%,8.16%.Through the data,the antibiotic resistance rate of gentamycin was higher.Conclusion:Compound drug and active antibacterial agent are more effectively.The measures of cleaning the sanitary status in patient's living space and improving immunity can help to control and treat acinetobacter baumannii.
