Molecular Typing of Fungi: Introduction, Common Molecular Typing Method, and Application

by
Various Candida species growth on HiCrome Candida Differential Agar

Introduction Molecular typing of fungi uses DNA-based methods to identify species and differentiate strains for clinical, epidemiological, and environmental studies. Key techniques include Internal Transcribed Spacer (ITS) sequencing (the standard for identification), Multilocus Sequence Typing (MLST), restriction fragment length polymorphism (RFLP), and Whole Genome Sequencing (WGS). These methods are crucial for tracking …

Fungal Identification by PCR-Sequencing (Sanger): Introduction, Principle, Clinical Significance, and Keynotes

by
Pure culture of Candida

Introduction Accurate identification of fungi is critical for clinical, environmental, and epidemiological purposes. Traditional culture and morphology-based methods are time-consuming and may misidentify cryptic or closely related species. PCR amplification followed by Sanger sequencing of conserved genetic loci (e.g., ITS, 18S rRNA, 28S rRNA, β-tubulin, …
