Abstract : | OBJECTIVE: Aspergillus section Nigri comprises a group of related species that include Aspergillus niger, A. welwitschiae, A. carbonarius, A. brasiliensis and A. tubingensis. Some of these species are morphologically very similar to A. niger but exhibit different patterns of susceptibility to antifungal agents; such is the case for A. tubingensis. Therefore, when diagnosing aspergillosis, it is important to identify the pathogen at the species level. This study aimed to identify the species of an Aspergillus spp. isolate (MM-82) obtained from a patient with a dermatosis localized to the right leg. MATERIALS AND METHODS: The MM-82 isolate was examined for macro- and microscopic morphology, conidia size and thermotolerance, and a phylogenetic analysis of a benA gene segment was performed for molecular identification. Susceptibility to antifungals was determined using antifungal microdilution according to the methodology of European Society of Clinical Microbiology and Infectious Diseases (EUCAST). RESULTS: Based on its phenotypic characteristics and the phylogenetic analysis of the sequence of a benA gene segment, the MM-82 isolate was identified as A. tubingensis. This fungus did not show resistance to antifungal agents commonly used for treatment. CONCLUSION: This study demonstrated that A. tubingensis can cause skin infection; this constitutes the first report of a case of aspergillosis caused by A. tubingensis in Mexico. |
