Overview

• 

   

  Microbiology is the study of small life in other words the study of all living organisms that are too small to be visible with the naked eye and are usually visible only through a microscope. Such organisms are referred to as microorganisms or microbes.

   

  Microorganisms were first observed over three hundred years ago and it is estimated that only one percent of the species of microorganisms that exist have been studied so far.

  Microorganisms

   

  Microorganisms include bacteria, archaea, viruses, protozoa, protists, microscopic fungi and moulds, yeasts, and microscopic algae. Note that viruses, though not always strictly classed as living organisms, are included. Bacteria are a large group of unicellular prokaryotic microorganisms. A few micrometres in length, bacteria have a wide range of shapes, ranging from spheres to rods and spirals. Archaea are single-celled microorganisms.

   

  Fungi are Eukaryotic, Heterotrophic Organisms

   

  The majority grow as multicellular filaments called hyphae forming a mycelium but some fungal species grow as single cells. Fungi that are largely invisible to the naked eye are classed as microorganisms. Yeasts, moulds and mushrooms are examples of fungi. Algae include many single-celled organisms that are also considered protozoa, such as Euglena. Blue-green algae are in fact bacteria that obtain their energy through photosynthesis. They are generally, and more correctly, referred to as cyanobacteria.

   

  Protozoa

   

  Protozoa are mostly single-celled, motile protists that feed by phagocytosis, though there are numerous exceptions. Examples of protozoa include Euglena, Amoeba, Paramecium and Toxoplasma. Protists are a diverse group of eukaryotic microorganisms. Protists were traditionally subdivided into the one-celled animal-like protozoa, the plant-like protophyta, and the fungus-like slime molds and water molds. These groups have been replaced by phylogenetic-based classifications but are still used as informal names for describing the various protists.

   

  Microbiology Encompasses

   

  Microbiology encompasses both prokaryotic and eukaryotic microorganisms but the majority of microbes are prokaryotes. Prokaryotes are a group of organisms that do not have a membrane-bound nucleus; they do not possess a nuclear membrane or nuclear envelope. They have DNA but the DNA is not enclosed in a membrane or envelope. In addition, they do not possess other membrane-bound organelles. Most are unicellular, but a few prokaryotes such as Myxobacteria have multicellular stages in their life cycles.
