Comparative Study of Ability for Growth Support and Species Differentiation by Colony Features on Commercial Chromogenic Agar, Pourmedia Vi Candida and CHROMagar Candida

Abstract

Ability for growth support and species differentiation by colony features were compared on two commercial chromogenic agars, CHROMagar Candida and newly developed Pourmedia Vi Candida. Eleven strains (ten species) of standard strains and twenty-four isolates (five species) of clinical strains were tested. All isolates were grown on both agar plates in 48 hours at 35°C, however, several species had not matured in 22 hours. Color of the colonies for each strain were stable on both agars. The results show that Pourmedia Vi Candida is equivalent to CHROMagar Candida in its ability to differentiate species as a primary culture plate.
