During the mycological analysis of skin and nail samples taken from patients with
onychomycosis and tineas in Assiut city, it is interesting to report that yeast fungi
were the main causal agents being cultured from 45.79% of total cases. In general,
21 species of yeast were isolated. Some of these are reported for the first time from
clinical specimens. From the literature available up-to-date around the world, this
study reports for the first time Saccharomycopsis fibuligera as the causal agent of four
clinical cases: two onychomycoses, one tinea capitis and one tinea amiantacea. Also,
it is reported here the second record for Trichosporon dohaense from a case of onychomycosis
of a 40-year-old woman (after its original description in 2009 by Taj-
Aldeen et al. J Clin Microbiol 47: 1791). Candida galli was also reported for the first
time from clinical specimen (tinea unguium) in 2014 by Gal
an-S
anchez et al. Mycopathol
178: 303, and this study reports the second case of onychomycosis by
C. galli. These strains were identified on the basis of their phenotypic, biochemical,
physiological and genotypic features. Strains and internal transcribed spacer (ITS)
gene sequences of these species are deposited at Assiut University Mycological Center
Culture Collection (AUMC) and National Center for Biotechnological Information
(NCBI) respectively.
