Bacteriology is the study of bacteria, their structure, functions, growth, and impact on the environment and humans. Bacteriologists use microscopes to identify and classify bacteria, which have different requirements for growth and can cause diseases. Bacteriology is a subcategory of microbiology, which also studies fungi, viruses, and parasites. Bacteriologists grow bacteria in the laboratory to isolate disease-causing bacteria and provide the right antibiotic treatment.
Bacteriology is the study of bacteria. Bacteria are microscopic organisms composed of a single cell. They are generally referred to as microorganisms because they are so small that a microscope is often needed to view them. An individual who studies, identifies, and classifies bacteria is called a bacteriologist. He usually does his studies in the laboratory.
The microscope is an essential tool for many bacteriologists as it can magnify tiny organisms many times their actual size. Anton van Leeuwenhoek’s refinement of the microscope opened up the tiny world of bacteria to all. It was 1676 when Leeuwenhoek first discovered bacteria.
Different classes of bacteria have different requirements for growth. Some cannot survive extreme temperatures, while others prefer very low or high temperatures. Many bacteria also differ in their oxygen and nutrient requirements. Other ways to identify bacteria are through their appearance or shape, the substances they produce, and their chemical reactions when tested in the laboratory. For example, rod-shaped bacteria are called bacilli, while round-shaped bacteria are known as cocci.
In bacteriology, the structure, functions and growth of various bacteria were discovered. Bacteriology has also explored the positive and negative impact of bacteria on the environment and on humans. Another important function is the identification of bacteria that often cause disease in humans and animals, and the mechanisms by which they cause infection. This is an important aspect of bacteriology, leading to the development of antibiotics or antibacterial drugs known to cure diseases caused by bacteria.
Bacteriology is a subcategory of microbiology, the study of microorganisms. In addition to bacteria, microbiology also studies fungi, viruses and parasites in association with the diseases they cause in humans. In medicine, microbiology and immunology are often studied together. Immunology deals with the responses of the immune system to the presence of microorganisms within the body. The treatment and prevention of diseases are made possible thanks to these studies.
Patients suspected of having infectious diseases are often asked to submit samples such as blood, urine, sputum and stool, for examination. In the laboratory, bacteriologists then grow the bacteria in the sample by planting them in certain growth media. Strict and sterile procedures are usually observed in growing bacteria in order to isolate the bacteria that cause disease and prevent the bacteria from spreading in the laboratory. Once the bacteria are identified, a proper diagnosis can be made and patients can be given the right antibiotic for treatment.
