Interpretive Summary:

Technical Abstract: Aspergillus contaminans is described as a new species from the fingernail of a patient with an infected nail. Phylogenetic analysis of four loci (ITS, calmodulin, beta tubulin and RNA polymerase beta, second largest subunit) showed that this species is most closely related to A. carlsbadensis from Aspergillus sect. Usti. Only one species from the section is known as a human pathogen, A. calidoustus. There was no growth of this species at 37 C so we infer that the A. contaminans was isolated as a contaminant of the infected nail. Aspergillus contaminans produced hulle cells that are very apparent on all media and displayed other characteristics of section Usti.
