Abstract

Abstract : Introduction: The fungal genus Colletotrichum is an uncommon cause of human infections. It has been implicated in cutaneous phaeohyphomycosis, artritis and keratitis secondary to traumatic implantation. Case presentation: We report two cases of keratitis due Colletotrichum truncatum in middle-aged, immunocompetent persons without history of trauma. The aetiological agents were identified based on DNA sequencing. Azoles and echinocandins showed high minimal inhibitory concentrations while amphotericin B was ≤ 0.25 mg l −1 . Both patients failed topical antifungal treatment and needed penetrating keratoplasty with a favourable outcome. Conclusion: C. truncatum caused keratomycosis which did not respond to topical antifungal agents. To the best of our knowledge these are the first reported cases of keratitis due to this fungus in Cuba and Latin-America and highlights the expanding spectrum of fungal agents causing eye infections.
