HKDSE生物 | Pathogenic Microorganisms 致病微生物
朗林生物專業補習，深入解析 Pathogenic Microorganisms，涵蓋 Bacteria、Viruses、Fungi 等。學習 Koch’s Postulates、Transmission Modes、Prevention Strategies，助你DSE滿分！
題目1: What are the key differences between bacteria and viruses as pathogens? (4 marks)
Bacteria are prokaryotic cells (無細胞核), can reproduce independently via binary fission (二分分裂), sensitive to antibiotics. Viruses are acellular (非細胞), obligate intracellular parasites (細胞內寄生), replicate using host machinery, not affected by antibiotics. Examples: Bacteria – TB (Mycobacterium tuberculosis); Virus – Influenza.
題目2: Explain Koch’s Postulates for proving a microorganism is pathogenic. (5 marks)
1. Microorganism found in all diseased hosts. 2. Isolate and culture pure strain. 3. Inoculate healthy host, reproduce disease. 4. Re-isolate identical microorganism. Exceptions for unculturable pathogens like viruses.
題目3: Describe two modes of transmission for pathogenic microorganisms. (4 marks)
Direct contact: Skin-to-skin (e.g., MRSA). Airborne: Droplets/coughing (e.g., COVID-19 via SARS-CoV-2). Prevention: Hand hygiene, masks.
題目4: How do vaccines prevent viral infections? Give an example. (4 marks)
Vaccines induce active immunity by presenting antigens (e.g., mRNA vaccines for COVID-19), stimulating memory B/T cells for antibody production on re-exposure. Example: HPV vaccine prevents cervical cancer-causing virus.
題目5: Why are antibiotics ineffective against fungi? Suggest control methods. (3 marks)
Fungi are eukaryotic (真核), share metabolic pathways with humans; antibiotics target prokaryotic features. Control: Antifungals (e.g., azoles), hygiene, avoid moist environments (e.g., Athlete’s foot – Tinea pedis).
