ABSTRACT
Objective To evaluate the performance of GP68 Antibiotic Susceptibility Testing card in testing the susceptibility of Streptococcus pneumoniae on VITEK 2-Compact system,taking E-test as reference.Methods A total of 98 strains of S.pneumoniae were collected and subjected to susceptibility testing using E-test and VITEK 2-Compact (AST-GP68) in Luzhou People's Hospital form January 1 to December 31,2015.Results According to the breakpoints of Clinical and Laboratory Standards Institute (CLSI),category agreement (CA) of penicillin was 80.6%.Very major error (VME) was 0.Major error (ME) was 12.2%,minor error (mE) was 7.1%.CA of ceffriaxone was 90.8%,VME 0,ME 4.1%,mE 5.1%.CA of cefotaxime was 91.8%,VME 0,mE 5.1%,mE 3.1%.CA of meropenem was 85.7%,VME 0,ME 2.0%,mE 12.2%.CA of other antibiotics (amoxicillin,ertapenem,erythromycin,tetracycline,chloramphenicol,telithromycin,linezolid,vancomycin,moxifloxacin,ofloxacin,levofloxacin) was 100%.Conclusions AST-GP68 on VITEK 2-Compact system may have false results of antimicrobial resistance to some antibiotics such as penicillin,ceftriaxone,cefepime,meropenem due to the defects of the underlying principle.Such false results should be verified by other methods in clinical practice.
