Its a fundamental course in Microbiology. Its meant for students, who have an idea and notion of biological sciences from intermediate and high school level. Its an introduction to the fascinating world of Microbiology: study of beings which can be seen through a microscope and some are macroscopic. It would first talk on the different fields of microbiology at an application level...the history of the development of microbiology. Some basic techniques in Microbiology are touched upon. They include sterilisation techniques and its principles. The physical and chemical agents used in Sterilisation. The methods of disinfection and the its difference from sterilisation. Physical agents include Heat , Steam at atmospheric pressure, Steam under atmospheric pressure. Temperatures at 100 degree celsius and temperatures above 100 degree celsius and temperature below100 degree celsius. They also include Microscopes and the types of microscopy. Light microscopy and electron microscopy. Also the stains and staining solutions with methodologies to increase contrast in viewing under a microscope. Staining techniques like Gram staining , Acid Fast staining, endospore staining , simple staining , Flagella staining and negative staining using nigrosin or India Ink , otherwise called capsular staining. The different components of biological dyes and the acidic or basic stains make up are explained in brief.
