1. Introduction to Microbiology:
Definition, common characteristics of all biological systems, A brief history of microbiology, Theories of spontaneous generation & biogenesis, Germ theories of disease, Characteristics of prokaryotic & eukaryotic cells, Whittaker’s five kingdom concept, Scope of microbiology in human welfare, Sanitation & environmental pollution control, Application of microbiology in medicine, agriculture, food & dairy, industry.
2. Microscopy and microscopic Examination:
Microscopy: Principal parts and functions of compound light microscope, the path of light, calculation of total magnification, definition of resolution, Principle mechanism, applications, advantages and limitations of Light ( Bright-field, Dark-field, fluorescence, phase-contract and confocal ) and electron ( transmission and scanning ) microscopy.
Staining: Definition, Staining procedure, Different types of staining, Types of dyes used in staining, mechanism of gram-staining.

3. Major groups of microorganisms:

Bacteria: Diagram of typical bacterial cell, size, shape and arrangement structures external to the cell wall, structure and chemical composition of cell wall, structures internal to the cell wall, concept of spores and cysts, classification, taxonomy, nutrition, nutritional types of bacteria, physical conditions required for growth (temperature, gaseous requirements), oxygen toxicity, reproduction and growth carve, synchronous growth, oxygenic & anoxygenic phototropic bacteria.
Fungi: Characteristics, morphology, classification, growth & reproduction, importance in natural process.
Virus: Characteristics and classification.
Salient features of Algae, Protozoa, Cyanobacteria and Actinomycetes.

4. Culture techniques:

Definition of culture media, Types of media, Preparation of media, Composition of media, Distinguish between pure culture and mixed culture, method of isolating pure cultures, Different methods for preservation of pure culture, quantitative measurement of growth.
5. Control of Microbial Growth:
Principles of microbial control (Sterilization, disinfection, antisepsis, degermation, sanitization), Physical methods of microbial control (heat, moist heat, autoclave, pasteurization, dry heat sterilization, filtration, low temperature, desiccation, osmotic pressure, radiation), Chemical methods of microbial control (various disinfectants and antiseptics).
