The application of microbiology in pharmaceutical and healthcare environments is stated as pharmaceutical microbiology. It is a branch of microbiology that recognizes that the enormously diverse range of microorganisms in the environment has abundant possibilities, some of which are beneficial and others which are harmful. It also underlines the significance of the presence of a wide range of microorganisms and toxins (microbial by-products such as endotoxins and pyrogens) in pharmaceutical raw materials, finished products, intermediates, and pharmaceutical manufacturing environments, as well as microbiological control of pharmaceutical products and manufacturing environments.
Pharmaceutical biotechnology is a dynamic and rapidly growing discipline in which biotechnology principles are applied to drug development. Pharmaceutical biotechnology industries create biotechnological products using recombinant DNA technology, which involves genetic manipulation of cells, or monoclonal antibodies.
