The development of blue colonies after 48 h of incubation at 37[degrees]C in Chromagar[R] Medium and the distribution of blastospores along pseudomycelium
observed in the microcultures (Figure 1) determined that all isolates belong to Candida tropicalis.
A total of 485 samples were collected from all patients; the direct microscopic examination was positive in 385 specimens (79.3%) showing filaments in 371 cases (96.3%), yeast and pseudomycelium
in two cases (0.5%), and both filaments with spores in 12 cases (3.1%).
Malassezia spp are globose to ellipsoidal lipophilic yeast (Matousek and Cambell, 2002) with thick wall and do not produce pseudomycelium
Several of these species produced pseudomycelium
or mycelium during growth, even a few of the true yeast species (Golonka, unpub, data; Kurtzman and Fell, 1998).
Citrus sinensis Budding, spherical to Candida tropicalis elongate cells, forming pseudomycelium
Lycopersicon Non septate mycelia Rhizopus stolonifer esculentum Sporangiospores are directly opposite the branched rhizoids.
Yeast isolates were examined for assimilation of sugars and citrate, pseudomycelium
formation and urease production before being identified according to Kreger van Rig (1984) and Barnett et al.
