Sl. Pendland et al., COMPARISON OF CHARCOAL-BASED AND STARCH-BASED MEDIA FOR TESTING SUSCEPTIBILITIES OF LEGIONELLA SPECIES TO MACROLIDES, AZALIDES, AND FLUOROQUINOLONES, Journal of clinical microbiology, 35(11), 1997, pp. 3004-3006
We compared growth characteristics of 46 Legionella strains grown on b
uffered charcoal yeast extract alpha (BCY alpha) agar and buffered sta
rch yeast extract (BSYE) agar and MICs of macrolides, azalides, and fl
uoroquinolones for these organisms. Growth was poor and not reproducib
le on BSYE agar. Growth was excellent on BCYE alpha, and MICs were eas
y to interpret. BCYE alpha is superior to BSYE for testing susceptibil
ities of Legionella species by agar dilution.
