Dual panel multiplex PCR assay for rapid detection of medically important fungi and resistant species of Candida and Aspergillus

Invasive fungal infections (IFIs) have risen dramatically in recent years among high risk immunocompromised patients. Rapid detection of fungal pathogens is crucial to timely and accurate antifungal therapy. Two multiplex polymerase chain reaction (PCR) assays were developed to detect major fungal s...
