Microbiology is defined as "the study of organisms too small to be clearly seen by the unaided eye." These organisms include viruses, bacteria, algae, fungi, archaea, and protozoa. When studying microorganisms, microbiologists are concerned with characteristics and functions such as morphology, cytology, physiology, ecology, taxonomy, genetics, and molecular biology.
Microbiology can be broken down into several branches of focus: food and dairy, public health, agriculture, industry, immunology and medical microbiology.
For those studying microbiology, especially medical students, the Internet is an excellent resource. Some of the best websites are listed below, categorized by topic for quick reference.
