    • Course Title: Molecular Diagnostics (MIC661)
    • Instructor: Dr. Muhd Hanis bin Md Idris
    • Course Description: Applications of molecular methods in diagnosing infectious diseases, conducting epidemiological investigations, and controlling infections in humans and plants. Nucleic acid amplification methods for pathogen detection will be highlighted, along with molecular methods for chromosomal and plasmid profiling, DNA fingerprinting, detection of drug resistance and virulence genes, molecular strain typing, and epidemiology analysis. Emerging technologies like mass spectrometry and sequencing-based pathogen identification will also be covered.
    • Course Learning Outcomes: Explain basic principles of DNA hybridization, PCR and genome sequencing techniques, along with their applications in diagnosing infectious diseases (C2). Students should also elaborate and review current molecular diagnostic techniques for pathogen detection (C5). Finally, students will be able to manipulate lab experiment results and present interpretations in written form (P4).

    Molecular Diagnostics

    • What is molecular diagnostics?: MDx tests analyze DNA, RNA, or protein biomarkers to identify diseases, predict disease courses, evaluate treatment responses, or assess individual disease predispositions.
    • Why molecular diagnostics?: High use due to specificity, sensitivity, and personalized medicine potential.
    • Specificity: Ability of a diagnostic test to correctly identify individuals without a disease (low false positives).
    • Sensitivity: Ability of a diagnostic test to correctly identify individuals with a disease (low false negatives).
    • Personalized medicine: Healthcare approach tailoring treatment to individual genetic, environmental, and lifestyle factors.
    • Market Size: Projected to increase from 8.5billionto8.5 billion to 8.5billionto20 billion by 2030.
    • Technology advancements: Polymerase Chain Reaction (PCR) increases the sensitivity of detection by amplifying DNA, allowing detection of minute amounts of genetic material. Next-Generation Sequencing (NGS) allows for high throughput sequencing, identifying a wide range of pathogens. Microarray enables simultaneous detection of multiple sequences. Fluorescence in situ hybridization (FISH) uses fluorescent probes to detect DNA or RNA sequences within tissue samples
    • Applications & Technology: Molecular diagnostics are used in health, medicine, forensics, pharmaceutical industry, biological warfare, and drug discovery.
