Cultural characterization and differentiation of nocardiae
Keyword(s):
Cultural and colonial morphology of 120 strains of nocardiae had been determined in three different semisynthetic media. On the basis of ability or inability to grow in the most reduced medium, and of growth pattern observed in the other liquid media, the nocardiae were categorized in six cultural groups. The reproducible and clear-cut cultural properties are considered a useful criterion for species differentiation.
