Infections caused by fungi of the Scedosporium/Pseudallescheria complex in veterinary species

Fungi belonging to the Scedosporium/Pseudallescheria complex (SPCF) have been known to cause human infections for nearly a century and are important human pathogens, with an increasing frequency of infection in patients with underlying conditions. There appears to be a lower incidence of infections with SPCF in veterinary species, although this may be related to a lack of awareness of these diseases. Important recent taxonomic changes in this group of fungi include the classification of Pseudallescheria boydii and Scedosporium apiospermum as two distinct species and the identification of new pathogenic species of SPCF. In this article, the literature on natural and experimental infections caused by SPCF in veterinary species is reviewed. The importance of an accurate identification of veterinary isolates by molecular methods is stressed, especially since virulence and susceptibility to antimycotic drugs of different species may vary.
