Abstract

Dematophytes invade hosts when their state is suitable for the production of their pathogenicity. When the host's resistance is reduced, the prevalence of dermatophytoses can be extremely high or the symptomatology can be very unusual. It is suspected that the 'maladie dermatophytique' and pherhaps dermatophytic mycetoma develop in such situations. The fact is that the behaviour of dermatophytes does not differ from that of the so-called opportunistic fungi and in some cases it is possible to speak of dermatophytic asthenomycosis.

Analysis of the dermatophyte Trichophyton rubrum expressed sequence tags.

BACKGROUND: Dermatophytes are the primary causative agent of dermatophytoses, a disease that affects billions of individuals worldwide. Trichophyton rubrum is the most common of the superficial fungi. Although T. rubrum is a recognized pathogen for humans, little is known about how its transcriptional pattern is related to development of the fungus and establishment of disease. It is therefore necessary to identify genes whose expression is relevant to growth, metabolism and virulence of T. rubrum. RESULTS: We generated 10 cDNA libraries covering nearly the entire growth phase and used them to isolate 11,085 unique expressed sequence tags (ESTs), including 3,816 contigs and 7,269 singletons. Comparisons with the GenBank non-redundant (NR) protein database revealed putative functions or matched homologs from other organisms for 7,764 (70%) of the ESTs. The remaining 3,321 (30%) of ESTs were only weakly similar or not similar to known sequences, suggesting that these ESTs represent novel genes. CONCLUSION: The present data provide a comprehensive view of fungal physiological processes including metabolism, sexual and asexual growth cycles, signal transduction and pathogenic mechanisms.
