Candida inconspicua (Lodder & Kreger-van Rij) S.A. Meyer & Yarrow<br />

Candida inconspicua is a rare cause of candidaemia.<br />

RG-1 organism.<br />

Culture: Colonies (SDA) white to cream-coloured smooth, glabrous, yeast-like.<br />

Microscopy: Ovoidal budding blastoconidia, 2.0-5 x 5.0-11.0 µm.<br />

India Ink Preparation: Negative - no capsules present.<br />

Dalmau Plate Culture: Spherical to ovoid budding yeast cells only. Primitive<br />

pseudohyphae may be produced after 14 days.<br />

Physiological Tests: + Positive, - Negative, v Variable, w Weak, s Slow<br />

Germ Tube - L-Sorbose - L-Arabinose - D-Glucitol -<br />

Fermentation Sucrose - D-Arabinose - α-M-D-glucoside -<br />

Glucose - Maltose - D-Ribose - D-Gluconate -<br />

Galactose - Cellobiose - L-Rhamnose - DL-Lactate +<br />

Sucrose - Trehalose - D-Glucosamine + myo-Inositol -<br />

Maltose - Lactose - N-A-D-glucosamine + 2-K-D-gluconate -<br />

Lactose - Melibiose - Glycerol + D-Glucuronate -<br />

Trehalose - Raffinose - Erythritol - Nitrate -<br />

Assimilation Melezitose - Ribitol - Urease -<br />

Glucose + Soluble Starch - Galactitol - 0.1% Cycloheximide -<br />

Galactose - D-Xylose - D-Mannitol - Growth at 40 O C +<br />

Key Features: Germ tube negative yeast and sugar assimilation pattern and colonies<br />

are white on Candida CHROMagar.<br />

Antifungal Susceptibility: C. inconspicua limited data available (Guitard et al.<br />
