MICROBIOLOGY AND PARASITOLOGY Categories of Diseases Caused by Pathogens Introduction to Microbiology What is Microbiology? Biology is the study of living organisms. Microbiology is an advanced biology course. Microbiology 3 is the study of microbes, which are extremely small (microscopic) living organisms and certain nonliving entities. Living microbes are known as cellular microbes or microorganisms; examples include bacteria, archaea, some algae, protozoa, and some fungi. Nonliving microbes are known as acellular microbes or infectious particles; examples include viroid, prions, and viruses. Microbes are ubiquitous (i.e., they are found virtually everywhere). Acellular and Cellular Microbes Microbes Microbes play significant roles in our lives; they are essential for life on this planet. Photosynthetic algae and bacteria (such as cyanobacteria) produce much of the oxygen in our atmosphere. Microorganisms are involved in the decomposition of dead organisms and waste products. Saprophytes – are organisms that live on dead and/or decaying organic matter. Bioremediation 3 The use of microbes to clean up toxic wastes and other industrial waste products. The microbes that cause disease are Microbes as Saprophytes sometimes referred to as
