WAYNE, Pa.--(BUSINESS WIRE)--With the increased incidence of systemic fungal infections and the growing number of antifungal agents, laboratory methods to guide the selection of antifungal therapy have gained greater attention. Clinical and Laboratory Standards Institute (CLSI) has recently published an updated standard, Reference Method for Broth Dilution Antifungal Susceptibility Testing of Filamentous Fungi; Approved Standard—Second Edition (M38-A2), which describes a method for testing the susceptibility of filamentous fungi (moulds) that cause invasive (Aspergillus spp., Fusarium spp., Rhizopus oryzae [R. arrhizus], Pseudallescheria boydii [Scedosporium apiospermum], S. prolificans, Sporothrix schenckii, and other opportunistic pathogenic moulds) and cutaneous (dermatophyte, Trichophyton, Microsporum, and Epidermophyton spp.) fungal infections to antifungal agents.
