Microscopy and culture of fungal disease
The clinical mycological laboratory strives to provide an accurate and rapid diagnosis of suspected fungal disease, or exclude its possibility. The most common and most traditional methods for demonstrating fungi in tissue and body fluids are microscopy and culture. The techniques discussed in this chapter are not exhaustive but have proved to be efficient for the visualization and recovery of fungi from clinical samples. In general, these methods do not require expensive or specialist equipment. The clinician’s presumptive diagnosis may help with the selection of the most appropriate specimen and aid the laboratory in the method of processing and selection of the primary culture media. However, all too often there is scant clinical information provided to the laboratory, and indeed a fungal infection may initially not have been suspected.
