ABSTRACT
OBJECTIVE To discuss the best scheme for fungemia detection by analyzing and comparing the ability and performance characteristics of the BACTEC 9120 automated blood culture system and 4 kinds of blood culture bottles in the detection of simulated fungemia.METHODS Simulated blood culture was produced using 65 fungi isolates from clinical specimens and BACTEC Plus Aerobic/F,Plus Anaerobic/F,Peds Plus/F and Myco/F Lytic blood culture bottles and detected by BACTEC 9120 automated blood culture system.The final inoculum densities were 1-5 CFU/ml blood.The(time to detection TTD) of simulated blood culture with different concentrations of suspension produced using 2 kinds of standard strains and 4 kinds of blood culture bottles was compared.RESULTS From the 260 bottles in this study 216 had growth detected by the BACTEC 9120 blood culture system.The positive rates of BACTEC Plus Aerobic/F and Anaerobic/F,which were 90.77%and 41.54%,respectively,were significantly(P
