INTRODUCTION TO MICROBIOLOGY Dr. Nain Taara Senior Assistant Professor  WHAT IS MICROBIOLOGY? Microbes, or microorganisms are minute living things that are usually unable to be viewed with the naked eye. What are some examples of microbes? Bacteria, fungi, protozoa, algae, viruses are examples! Some are pathogenic Many are beneficial DR.T.V.RAO 3 MD  BRANCHES OF MICROBIOLOGY Bacteriolo gy Mycology Virology Immunolo gy Parasitolo gy 4  DEFINING MICROBIOLOGY Microbiology defined as ‘’The study of organisms too small to be seen with the naked eye’’ These organisms include viruses, bacteria, algae, fungi, and protozoa. Microbiologists are concerned with characteristics and functions such as morphology, cytology, physiology, ecology, taxonomy, genetics, and molecular biology.

Vaccines and interferons are being investigated to prevent and cure viral diseases. The use of immunology to identify some bacteria according to serotypes (variants within a species) was DR.T.V.RAO MD 14 THE BIRTH OF MODERN CHEMOTHERAPY Treatment with chemicals is chemotherapy. Chemotherapeutic agents used to treat infectious disease can be synthetic drugs or antibiotics. Antibiotics are chemicals produced by bacteria and fungi that inhibit or kill other microbes. Quinine from tree bark was long used to treat malaria. 1910: Paul Ehrlich developed a synthetic DR.T.V.RAO 15 MD  COMMONLY USED ANTIBIOTICS Penicillin Cephalosporins, Tetracycline's Quinolones Vancomycin Chloramphenicol Drugs for Tuberculosis eg Streptomycin DR.T.V.RAO 16 MD  COMMONLY USED VACCINES Small pox eradicated BCG, MMR Polio oral Vaccine Triple Antigen DR.T.V.RAO 17 MD
