Genetic relatedness versus biological compatibility between Aspergillus fumigatus and related species.

ABSTRACT: Aspergillus section Fumigati contains 12 clinically relevant species. Among these Aspergillus species, A. fumigatus is the most frequent agent of invasive aspergillosis, followed by A. lentulus and A. viridinutans. Genealogical concordance and mating experiments were performed to examine the relationship between phylogenetic distance and mating success in these three heterothallic species. Analyses of 19 isolates from section Fumigati revealed the presence of three previously unrecognized species within the broadly circumscribed species A. viridinutans. A single mating type was found in the new species Aspergillus pseudofelis and Aspergillus pseudoviridinutans, but in Aspergillus parafelis, both mating types were present. Reciprocal interspecific pairings of all species in the study showed
