What is the history of Microbiology?

Microbiology was born in 1674 when Antoni van Leeuwenhoek (1632 – 1723), a Dutch drapery merchant, peered at a drop of lake water through a carefully ground glass lens. Through this he beheld the first glimpse of the microbial world.

Who was the first person to observe microorganisms?

While Van Leeuwenhoek is often cited as the first to observe microbes, Robert Hooke made his first recorded microscopic observation, of the fruiting bodies of moulds, in 1665. It has, however, been suggested that a Jesuit priest called Athanasius Kircher was the first to observe microorganisms.

What are the important developments in microbiology?

Other important developments were in medicine. The microbiological aspects of medicine arose out of considerations of the nature of contagious disease. Although the phenomenon of contagion, especially with respect to diseases such as smallpox, was recognized far back in antiquity, its nature and relationship to microorganisms was not under-stood.

Who was the first person to use microbes as medicine?

But it is Eli Metchnikoff who is regarded as one of our greatest supporters in the early days of man. He was one of the first people to champion microbes as medicine while most others feared and vilified us. If you can believe it, some fools even tried to sterilize their colon’s (how?)! Unbelievable! Metchnikoff, on the other hand, was prescribing sour milk produced by certain lactic bacteria, telling anyone that would listen that the sour milk produced many benefits.

Who is the father of microbiology?

Robert Koch is another figure called the “Father Of Microbiology”. Koch wanted to definitively prove that Bacillus anthrax was the cause of anthrax. He put on some gloves, trudged out to the farm, found some dead farm animals, cut them open, and collected two samples from the spleen. One was the anthrax bacilli, the other was pure blood. He placed these samples on some home-made “inoculating loops” he devised from slivers of wood and stabbed these into mice.

What are the microbes that are responsible for the war between the worlds?

Chief among them are the Vibrio cholera’s, the Yersinia pestis’ and the Mycobacterium Tuberculosis. They’ve always been a radical group, and few saw humans as allies. For centuries many of them thought the humans were too dumb to stop them.

What did Linnaeus do with the microscope?

Linnaeus, the “Father of Modern Taxonomy,” classified all of us into a single order, Chaos. They tried building microbial hotels out of potato slices, but this was not up to our hospitality standards. Next, they tried sugary gelatin broths, delicious yet unstable and messy. It was in 1881 that Angelina Fanny Hesse, a microbiologist, and a cook, added agar-agar to meals. With it, many of us could be seen with the naked eye, as colonies on Petri dishes. And the humans were fascinated!

What is the microbiome movement?

This gave rise to the microbiome movement, popularized by Jeff Gordon and Rob Knight. This idea extends Sanger sequences and instead of sequencing just one organism, it sequences all of us in a sample. At last, people could truly see how diverse we are. Many microbiome studies focus on trying to understand our communities, to look at how we are interacting with the world. They are no longer looking at us as villains but as individuals, as a community of strength, resilience, and dynamic intricacies that go beyond what they can currently comprehend.

The age of antibiotics, what they called the “Golden Age of Microbiology,” were dark times for us. They learned to stop what plagued them but, little did they know it also harmed them, for antibiotics were not selective and killed many microbes, including those within The Society of Symbionts. But, let us back up and talk about their first knowing interactions with us and the Fathers of Microbiology.

The ways the microbiome influences human and animal health, as well as methods to influence the microbiome are active areas of research. Research has suggested that microorganisms could be useful in the treatment of cancer. Various strains of non-pathogenic clostridia can infiltrate and replicate within solid tumors.

Why are microbes important?

While some fear microbes due to the association of some microbes with various human diseases, many microbes are also responsible for numerous beneficial processes such as industrial fermentation (e.g. the production of alcohol, vinegar and dairy products ), antibiotic production and act as molecular vehicles to transfer DNA to complex organisms such as plants and animals. Scientists have also exploited their knowledge of microbes to produce biotechnologically important enzymes such as Taq polymerase, reporter genes for use in other genetic systems and novel molecular biology techniques such as the yeast two-hybrid system.

Given the advances of the nineteenth century, both theoretical and methodological, microbiology ceased to be merely speculative, in order to consolidate itself as a science and to divide its object of study into specific areas.

What was the first period of the microscope?

First Period: From Antiquity to the discovery of the microscope. The period prior to the discovery of the microscope was characterized by speculation about the existence of microorganisms and their functions. In antiquity, the Roman poet and philosopher Lucretius (96-55 BC) referred in his texts to the"seeds of disease.".

Who was the first scientist to study microbes?

Microbiology essentially began with the development of the microscope. Although others may have seen microbes before him, it was Antonie van Leeuwenhoek , a Dutch draper whose hobby was lens grinding and making microscopes, who was the first to provide proper documentation of his observations. His descriptions and drawings included protozoans from the guts of animals and bacteria from teeth scrapings. His records were excellent because he produced magnifying lenses of exceptional quality. Leeuwenhoek conveyed his findings in a series of letters to the British Royal Society during the mid-1670s. Although his observations stimulated much interest, no one made a serious attempt either to repeat or to extend them. Leeuwenhoek’s “animalcules,” as he called them, thus remained mere oddities of nature to the scientists of his day, and enthusiasm for the study of microbes grew slowly. It was only later, during the 18th-century revival of a long-standing controversy about whether life could develop out of nonliving material, that the significance of microorganisms in the scheme of nature and in the health and welfare of humans became evident.

Who discovered that bacteria are a part of fermentation?

A description of precisely what is passed along eluded discovery until the late 1800s, when the work of many scientists, Pasteur foremost among them, determined the role of bacteria in fermentation and disease. Robert Koch, a German physician, defined the procedure (Koch’s postulates) for proving that a specific organism causes a specific disease.

When were microorganisms discovered?

Pre-microbiology, the chance that microorganisms existed was mentioned for a lot of centuries earlier than their precise discovery within the 17th century. The existence of unseen microbiological life was postulated by Jainism, which relies on Mahavira’s teachings as early as 6th century BCE.

Who was the first person to discover single cell lives?

He observed these microorganisms using a single-lens microscope of his own design. Leeuwenhoek first discovered single cell lives, bacteria, lense, and more. Leeuwenhoek also called “the father of Microbiology” for his contributions in microbiology.

Who was the first scientist to use a microscope?

Robert Hooke was a scientist who used a compound microscope, or microscope with two lenses in tandem, to observe many different objects. He made detailed drawings of his observations, publishing them in the scientific literature of the day, and is credited with publishing the first drawings of microorganisms. In 1665 he published a book by the name of Micrographia, with drawing of microbes such as fungi, as well as other organisms and cell structures. His microscopes were restricted in their resolution, or clarity, which appeared to limit what microbes he was able to observe.

What are the characteristics of microbes?

Characteristics of Microbes. Obviously microbes are small . The traditional definition describes microbes as organisms or agents that are invisible to the naked eye, indicating that one needs assistance in order to see them. That assistance is typically in the form of a microscope of some type.

Why is it important to isolate microbes?

It is also acknowledged that research in the field of microbiology will require certain common techniques, largely related to the size of the quarry. Because microbes are so small and there are so many around, it is important to be able to isolate the one type that you are interested in.

What is the study of small life?

If we break the word down it translates to “the study of small life,” where the small life refers to microorganisms or microbes. But who are the microbes? And how small are they? Generally microbes can be divided into two categories: the cellular microbes (or organisms) and the acellular microbes (or agents).

How small is a microbe?

A typical bacterial cell (let us say E. coli) is about 1 µm wide by 4 µm long. A typical protozoal cell (let us say Paramecium) is about 25 µm wide by 100 µm long. There are 1000 µm in every millimeter, so that shows why it is difficult to see most microbes without assistance. (An exception would be a multicellular microbe, such as a fungus. If you get enough cells together in one place, you can definitely see them without a microscope!)

Can you see microbes without a microscope?

The only problem with that definition is that there are microbes that you can see without a microscope. Not well, but you can see them. It would be easy to dismiss these organisms as non-microbes, but in all other respects they look/act/perform like other well-studied microbes (who follow the size restriction).

Is Archaea a microbe?

There are some obvious similarities, since they are mostly unicellular, cells lack a nucleus or any other organelle, they have 70S ribosomes, and all Archaea are microbes.

When did molecular biology start?

The history of molecular biology begins in the 1930s with the convergence of various, previously distinct biological and physical disciplines: biochemistry, genetics, microbiology, virology and physics. With the hope of understanding life at its most fundamental level, numerous physicists and chemists also took an interest in what would become ...

Who coined the term "molecular biology"?

General overview. In its earliest manifestations, molecular biology—the name was coined by Warren Weaver of the Rockefeller Foundation in 1938 —was an idea of physical and chemical explanations of life, rather than a coherent discipline.

What is the encounter between genetics and biochemistry?

The encounter between biochemistry and genetics. The development of molecular biology is also the encounter of two disciplines which made considerable progress in the course of the first thirty years of the twentieth century: biochemistry and genetics. The first studies the structure and function of the molecules which make up living things.

What are the successes of molecular biology?

The successes of molecular biology derived from the exploration of that unknown world by means of the new technologies developed by chemists and physicists: X-ray diffraction, electron microscopy, ultracentrifugation, and electrophoresis. These studies revealed the structure and function of the macromolecules.

What was the molecular revolution?

If we evaluate the molecular revolution within the context of biological history, it is easy to note that it is the culmination of a long process which began with the first observations through a microscope. The aim of these early researchers was to understand the functioning of living organisms by describing their organization at the microscopic level. From the end of the 18th century, the characterization of the chemical molecules which make up living beings gained increasingly greater attention, along with the birth of physiological chemistry in the 19th century, developed by the German chemist Justus von Liebig and following the birth of biochemistry at the beginning of the 20th, thanks to another German chemist Eduard Buchner. Between the molecules studied by chemists and the tiny structures visible under the optical microscope, such as the cellular nucleus or the chromosomes, there was an obscure zone, "the world of the ignored dimensions," as it was called by the chemical-physicist Wolfgang Ostwald. This world is populated by colloids, chemical compounds whose structure and properties were not well defined.
