BAVA, Amadeo Javier  and  ZUIANI, María Fernanda. Quality assessment of the mycological diagnosis: cultures. Acta bioquím. clín. latinoam. [online]. 2007, vol.41, n.1, pp.125-129. ISSN 0325-2957.

The ability to identify different fungal strains at genera or specie level for participant laboratories of the Mycology Sub-Program, was evaluated. Taking into account all results as a whole, 66% of laboratories identified the strains correctly, while another 25% recognized the strains partially. Regarding dermatophytes, a higher percentage of correct responses for Trichophyton mentagrophytes recognition was observed with respect to (76%) those of the evaluated Microsporum species: M. canis (66%) and M. gypseum (65%). The results produced by the identification of yeasts species showed 2 different groups: one constituted by Candida albicans and Cryptococcus neoformans, with higher percentages of correct responses (87 and 95%, respectively) and another one constituted by C. tropicalis and C. glabrata, which presented difficulties for their correct identification (28 and 32% correct responses). The evaluated species of Aspergillus (A. fumigatus and A. niger) were recognized by 63% and 72% of the participants. The results obtained, considered as acceptable, show the need to improve the evaluated capacity, taking into account their decisive influence on mycologic diagnosis quality.
