Other scientists recognized the importance of bacteria in agriculture and the dairy industry. There have also been some vaccines that were not as effective and have side effects for example, typhoid vaccine. Immunology deals with the responses of the immune system to the presence of microorganisms inside the body.


While Cohn and others advanced knowledge of the morphology of bacteria, other researchers, such as Louis Pasteur and Robert Kochestablished the connections between bacteria and the processes of fermentation and disease, in the process discarding the theory of spontaneous generation and improving antisepsis in medical treatment.

Ad In bacteriology, the structure, functions, and growth of various bacteria have been discovered. Identification and characterizing of bacteria being associated to diseases led to advances in pathogenic bacteriology.

He identified bacteria as the cause of infectious diseases and process of fermentation in diseases. His research led flirt in tagalog quotes twitter a study of disease prevention and the treatment of disease by vaccines and immune serums a branch of medicine now called immunology.

Bacteriology has also explored the positive and negative impact of bacteria in the environment and in human beings.


Both Koch and Pasteur played a role in improving antisepsis in medical treatment. The organisms seem to correspond with some boaventura online dating the very large forms of bacteria as now recognized. The importance of bacteria was recognized as it led to a study of disease prevention and treatment of diseases by vaccines.

Patients suspected of having infectious diseases are often requested to submit samples such as blood, urinesputum, and feces, for examination.

Important discoveries came in andwhen Pasteur succeeded in immunizing animals against two diseases caused by bacteria. Bacteriology has also provided discovery of antibiotics. The improvement of the microscope by Anton van Leeuwenhoek has opened the minute world of bacteria to everyone.

Top 10 facts about the world Bacteriology is the study of bacteria. Other ways to identify bacteria are through their appearance or shape, the substances they produce, and through their chemical reactions when tested in the laboratory.

This is an important aspect of bacteriology, which leads to the development of antibiotics or antibacterial drugs known to treat diseases caused by bacteria. In the laboratory, bacteriologists then grows the bacteria present in the sample by planting them in certain growth media.

Some cannot survive extremes of temperatures, while others prefer very low or high temperatures.


Different classes of bacteria have different requirements for growth. French Scientist Louis Pasteur developed techniques to produce vaccines. Between and Pasteur produced two successful vaccinations for animals against diseases caused by bacteria and it was successful.

Bacteriological study subsequently developed a number of specializations, among which are agricultural, or soil, bacteriology; clinical diagnostic bacteriology; industrial bacteriology; marine bacteriology; public-health bacteriology; sanitary, or hygienic, bacteriology; and systematic bacteriology, which deals with taxonomy.


Many bacteria also differ in their oxygen needs and nutrient needs. In his paper he described his method of preparing thin layers of bacteria on glass slides and fixing them by… The beginnings of bacteriology paralleled the development of the microscope.

Bacteriology has developed and can be studied in agriculturemarine biologywater pollutionbacterial genetics and biotechnology. As late as the midth century, bacteria were known only to a few experts and in a few forms as curiosities of the microscope, chiefly interesting for their minuteness and motility.

Treatment and prevention of diseases are made possible because of these studies. For example, rod-shaped bacteria are called bacilli, while round-shaped bacteria are known as cocci.

It was in when Leeuwenhoek first discovered bacteria. Bacteria are microscopic organisms composed of a single cell. In Koch published an important paper on the investigation, preservation, and photographing of bacteria.

The microscope is an essential tool for many bacteriologists as it can magnify the minute organisms many times their actual size.

Aside from bacteria, microbiology also studies fungiviruses, and parasites in association to the diseases they cause in man. The modern methods of bacteriological technique had their beginnings in —85 with the introduction of the use of stains and by the discovery of the method of separating mixtures of organisms on plates of nutrient media solidified with gelatin or agar.

They are generally referred to as microorganisms because they are so tiny that a microscope is often needed to visualize them. The first person to see microorganisms was probably the Dutch naturalist Antonie van Leeuwenhoekwho in described some animalcules, as they were then called, in water, saliva, and other substances.

Strict and sterile procedures are usually observed in growing the bacteria in order to isolate the bacteria causing the disease and to prevent the bacteria from spreading around the laboratory. Learn More in these related Britannica articles: Introduction[ edit ] Bacteriology is the study of bacteria and their relation to medicine.

This had an enormous positive effect on public health and gave a better understanding of the body and diseases. Once bacteria are identified, a proper diagnosis can be done and patients can be given the right antibiotic for treatment.

In medicine, microbiology and immunology are often studied together. Another important function is the identification of bacteria that often cause disease in man and animals, and the mechanisms of how they bring about infection.

History[ edit ] The discovery of the connection of microorganisms to disease can be dated back to the nineteenth century, when German physician Robert Koch introduced the science of microorganisms to the medical field.

These had been seen with a simple lens magnifying about — diameters. An individual who studies, identifies, and classifies bacteria is called a bacteriologist.
