Study of rapidity and quality for the VITEK susceptibility cards with 45 wells.
VITEK 45 wells Card was evaluated. Recent clinical isolates of gram-positive cocci (107) and gram-negative bacilli (179) were antimicrobial susceptibility testing by VITEK system in comparison with MIC-2000 system. The antimicrobial susceptibility results were available within of 8 h for gram-positive cocci without a part of MRSA. Enterobac-teriaceae were available within of 8 h and Pseudomonas aeruginosa were from 8 to 11 h. The antimicrobial susceptibility data had disagreement of 60% with EM, 46% with CLDM for Enterococcus faecium, 50% with CMZ for Citrobacter freundii, and 71% with CTM for Morganella morganii, whereas it was satisfactory agreement of 97.5% for gram-positive cocci and 98.2% for gram-negative bacilli. In using this procedure it was possible to provide accurate and rapid results of anti-microbial susceptibility tests for all organisms.
