The “Quick review on Microbiology & Serology aims to understand the morphology of bacteria, sterilization and disinfections techniques, immunity, antigen-antibody reaction and serological reaction. To develop the skill of various clinical testing techniques. By, emphasis on to understand the morphology of bacteria, sterilization and disinfections techniques, immunity, antigen-antibody reaction and serological reaction. To develop the skill of various clinical testing techniques.Bacteriology is a study of bacteria responsible for human illness. They are ubiquitous. Study of bacteriology helps in identification of infections / communicable diseases cause by them. It also helps in finding suitable anti microbial agent for treatmentImmunology and serology are closely associated subjects and are important from diagnostic point of view. Immunology is study of antigen or antibody produced in response to external invader while serology is invitro study of these changes.The Books covers the Principles of identification of bacteria, size, shape, arrangement; capsule, spore flagella etc. Principles of sterilization and disinfection. Principles of Bio-chemical reactions. Principles of Agglutination, Precipitation and compliment fixation reactions. Principles of various bacterial test.It includes a concepts of Morphology and Physiology of bacteria, Aerobic and Anaerobic Mycobacteria, Pyogenic cocci. Immunity, Antigen, Antibody and compliment. Autoimmunity and diseases.Contents-1. BACTERIOLOGY •Introduction to microbiology -Classification, morphology and physiology of bacteria.
