Accurate identification of fungal species, particularly Candida, is essential for the interpretation of anti-fungal sensitivity testing (MICs) and successful treatment. Identification of fungi based on phenotypic and morphological characteristics can be both difficult and slow. Classification of fungi by their ribosomal gene sequences is now widely accepted. PCR amplification of 18S ribosomal gene sequences followed by DNA sequencing and comparison to ribosomal sequence databases allows the classification of most Candida species and many other fungi. This broad-range fungal PCR can also be used to detect a wide range of fungal species in primary clinical specimens.

18S PCR, fungal PCR, broad-range fungal PCR, pan-fungal PCR, ribosomal PCR
