Fatal fungal endocarditis by Aspergillus udagawae: an emerging cause of invasive aspergillosis

Aspergillus udagawae has morphological similarities to Aspergillusfumigatus; however, it shows a low susceptibility to common antifungal drugs and poor in vitro sporulation. We present the first reported case of infectious endocarditis caused by A. udagawae. An awareness of this newly described Aspergillus species is vital for further clarification.
