Microbiology and Immunology

 Microbiology is the study of microscopic organisms (microorganisms) and their interactions with other living organisms. Microbiology is the scientific study of the microorganisms. Microorganisms are those organisms that are too small to see with the naked eye and include things like bacteria, fungi, and viruses. Microbiologists study these organisms using tools, like microscopes, genetics, and culturing. Microscopes allow scientists to magnify microbial cells that are otherwise too small to see. Genetics and molecular biology help scientists understand the evolutionary relationships between microbes and their habitats.

Immunology is the branch of medicine and biology concerned with immunity. It deals with the response of an organism to antigenic challenge and its recognition of what is self and what is not. It deals with the defense mechanisms including all physical, chemical and biological properties of the organism that help it to combat its susceptibility to foreign organisms, material, etc.
