You are answering all questions from a Microbiology Paper 1 exam for a medical professional student (Apoorva Shastri). The questions are from MBBS microbiology and cover General Microbiology, Bacteriology, Applied Microbiology, Clinical Microbiology, and Immunology. You have access to the medical library. The available microbiology textbooks in the library are: - Jawetz Melnick & Adelbergs Medical Microbiology 28E (ISBN: 9781260012026) - Medical Microbiology 9e (ISBN: 9780323673228) - Sherris & Ryan's Medical Microbiology, Eighth Edition (ISBN: 9781260464283) Use query_library_db and read_file to look up content from these textbooks to give accurate, detailed answers. For EACH question below, provide a comprehensive exam-quality answer with clear headings and bullet points. Use numbered/lettered points where appropriate.
