Os dejo el resumen de nuestro trabajo científico publicado en Diagnostic Microbiology and Infectious Diseases sobre la actividad de los fármacos antifúngicos denominados equinocandinas contra Candida albicans y dos especies relacionadas estrechamente con esta, Candida africana y Candida dubliniensis. Felicito a mis colegas Sandra Gil-Alonso, Nerea Jauregizar y Elena Eraso de la Facultad de Medicina de la Universidad del País Vasco (UPV/EHU) en Bilbao y Emilia Cantón del Hospital La Fe (Valencia), por su arduo trabajo.

Este es su Resumen:
Candida albicans remains the most common fungal pathogen. This species is closely related to 2 phenotypically similar cryptic species, Candida dubliniensis and Candida africana. This study aims to compare the antifungal activities of echinocandins against 7 C. albicans, 5 C. dubliniensis, and 2 C. africana strains by time–kill methodology. MIC values were similar for the 3 species; however, differences in killing activity were observed among species, isolates, and echinocandins. Echinocandins produced weak killing activity against the 3 species. In all drugs, the fungicidal endpoint (99.9% mortality) was reached at ≤31 h with ≥0.5 μg/mL for anidulafungin in 4 C. albicans and 1 C. dubliniensis, for caspofungin in 1 C. albicans and 2 C. dubliniensis, and for micafungin in 4 C. albicans and 1 C. dubliniensis. None of echinocandins showed lethality against C. africana. Identification of these new cryptic species and time–kill studies would be recommendable when echinocandin treatment fails.
