L. Lebrun et al., EVALUATION OF THE ETEST FOR RAPID SUSCEPTIBILITY TESTING OF MYCOBACTERIUM-AVIUM TO CLARITHROMYCIN, Journal of antimicrobial chemotherapy, 37(5), 1996, pp. 999-1003
MICs of clarithromycin were determined by the Etest method for thirty
clinical strains of Mycobacterium avium complex (MAC) and compared wit
h MICs results as determined by the reference agar dilution method. Ag
reement (within +/-1 log(2) dilution) between the Etest and the refere
nce method was 70% for susceptible strains and 100% for resistant stra
ins. No major errors resulting in misclassification in susceptibility
or resistance categories were detected for the Etest MIC method. It is
suggested that the Etest is easy to perform and is an accurate method
for determining susceptibility of MAC strains to clarithromycin.
