Abstract
Fungal infections of central nervous system (CNS) are increasingly encountered in various clinical settings. Any pathogenic fungus is able to produce CNS infection, though only certain groups are neurotropic. The outcome of CNS fungal infections depends on early diagnosis and prompt management. But, the early diagnosis faces stiff challenges due to general considerations of rarity of CNS fungal infection, non-specific clinical symptoms and signs and difficulty in collection of samples for conventional diagnosis. Application of genomic-based molecular techniques is usually rapid and sensitive and may detect the causative agent accurately and help appropriate and prompt antifungal therapy. These techniques can be applied either for detection of nucleic acid in clinical samples or for the accurate identification of fungi isolated from the clinical specimen. Detection of nucleic acid in clinical sample faces the challenge of extraction of nucleic acid, inadequate amount nucleic acid in sample and contamination during test procedure. The current chapter describes the existing knowledge on genomic-based molecular tests for diagnosis and monitoring of CNS fungal diseases.
