Exercise 8. Read and translate the text:

Microbiology

Microbiology is the scientific study of microscopic organisms, either unicellular (single cell), multicellular (cell colony), or acellular (lacking cells) including protozoans, yeasts, algae, molds, microscopic fungi, bacteria, and viruses. Microbiology is concerned with the structure, function, and classification of these organisms and with ways of controlling and using their activities.

Microbiology encompasses numerous sub-disciplines including virology, mycology, parasito-logy, and bacteriology. Its foundations were established in the later 19th century, with the work of Louis Pasteur and Robert Koch. Since then, the scientists have identified many disease-causing microorganisms and have developed means of controlling their harmful effects. In addition, they have discovered means of channeling the activities of various microorganisms to benefit medicine, industry, and agriculture. Molds, for example, produce antibiotics, notably penicillin.

Modern microbiology. The branches of microbiology can be classified into pure and applied sciences. Both general microbiology and its specialized branches are developing extremely vigorously. There are three fundamental reasons for such development. First, microbiology has had the advantage of a large number of new methods of research, through advances made in physics, chemistry, and engineering. Second, the practical usefulness of microorganisms has increased sharply since the 1940’s. Third, microorganisms are being used to solve some of the most important theoretical problems of biology, such as heredity and variability, the biosynthesis of organic compounds, and metabolic regulation.

Medical microbiology related to applied sciences is a branch of medicine concerned with the prevention, diagnosis and treatment of infectious diseases. There are four kinds of microorganisms that can cause infectious disease; bacteria, fungi, parasites and viruses. In addition, this field of science studies various clinical applications of microbes for the improvement of health as well.

A medical microbiologist studies the characteristics of pathogens, their modes of transmission, mechanisms of infection and growth. Using this information a treatment can be devised. Medical microbiologists often serve as consultants for physicians, providing identification of pathogens and suggesting treatment options. They may also assist in preventing or controlling epidemics and outbreaks of disease. Not all medical microbiologists study microbial pathology; some study common, non-pathogenic species to determine whether their properties can be used to develop antibiotics or other treatment methods.

History of Medical Microbiology

Anton van Leeuwenhoek (Антони ван Левенгук) is considered to be the one of the first to observe microorganisms using a microscope. In 1676, he (to observe) bacteria and other microorganisms, using a single-lens microscope of his own design.

In 1796, using an ancient Chinese technique for smallpox vaccination, Edward Jenner (to develop) a method using cowpox а to successfully immunize a child against smallpox. The same principles (to use) for developing vaccines today.

Following on from this, in 1857 Louis Pasteur also (to design) vaccines against several diseases as well as pasteurization for food preservation.

Joseph Lister is considered to be the father of antiseptic surgery. By sterilizing the instruments with diluted carbolic acid and using it to clean wounds, post-operative infections (to reduce) making surgery safer for patients.

In the years between 1876-1884 Robert Koch provided much insight into infectious disease. He (to be) one of the first scientists to focus on the isolation of bacteria in pure culture. This (to give) rise to germ theory, a certain microorganism being responsible for a certain disease. He (to develop) a series of criteria around this that have become known as the Koch's postulates.

In 1884 Hans Christian Gram developed the method of staining bacteria, to make them more visible and differentiable under a microscope. This technique (to use) widely today.

In 1929 Alexander Fleming developed the most commonly used antibiotic substance both at the time and now: penicillin.

Exercise 6: Read and translate the text:

Microorganisms

A microorganism or microbe is a microscopic organism which may be a single cell or multicellular organism. The study of microorganisms is called microbiology, a subject that began with Anton van Leewenhoek’s discovery of microorganisms in 1675, using a miscroscope of his own design.

All the existing microorganisms can be divided into two main groups – aerobic and anaerobic. Aerobic microorganisms must have atmospheric free oxygen for their life and growth. However one knows that free oxygen is not favourable for the development of anaerobic microorganisms.

Most bacterial species are either spherical, called cocci or rod -shaped, called bacilli. Some rod-shaped bacteria, called vibrios, are slightly curved or comma-shaped; others, called spirilla, can be spiral-shaped.

This wide variety of shapes is determined by the bacterial cell wall and cytoskeleton, and it is important because it can influence the ability of bacteria to acquire nutrients, attach to surfaces, swim through liquids etc.

When bacteria multiply they divide. The growing organism increases in size up to a certain limit and in due time divides. The process of division depends on the conditions of the environment. Under optimal conditions, bacteria can grow and divide extremely rapidly, and bacterial population can double as quickly as every 9.8 minutes.

If bacteria form a parasitic association with other organisms, they are classed as pathogens. Pathogenic bacteria are a major cause of human death and diseases and cause infections such as tetanus, typhoid fever, diphtheria, cholera and tuberculosis. Some organisms, such as Staphylococcus or Streptococcus, can cause skin infections, pneumonia, and meningitis.

Other bacteria are the essential part of the normal human flora and usually exist on the skin or mucous membrane without causing any disease at all. In fact they help to protect us from becoming infected with harmful microbes.

Bacteria frequently secrete chemicals into their environment in order to modify it favourably. The secretions are often proteins and may act as enzymes that digest some forms of food. The understanding of bacterial metabolism and genetics allow the use of biotechnology for the production of therapeutic proteins, such as insulin.

The study of bacteria is known as bacteriology, a branch of microbiology.

Exercise 6. Read and translate the text:

Alexander Fleming

Sir Alexander Fleming was a Scottish bacteriologist and Nobel Prize winner, best known for his discovery of penicillin.

Alexander Fleming was born in 1881. He did research work at one of the hospitals in London and became interested in bacterial action and antibacterial drugs. In 1922, during his work on the bacteriology of septic wounds, he discovered lysozyme, a ferment found in many animal tissues and secretions which attacks bacteria. He was already much preoccupied with the problem of discovering anti-bacterial agents that were not toxic or harmful to the living organism.

Fleming discovered penicillin by mistake when he was trying to study Staphylococcus bacteria in 1928. He was running experiments with the bacteria in his laboratory at London's St. Mary's Hospital, and set a laboratory dish containing the bacteria near an open window. Upon returning to the experiment, he found that some mould blown in through the open window onto the dish, contaminating the bacteria.

Instead of throwing away his spoiled experiment, Fleming looked closely at it under his microscope. Surprisingly, he saw not only the mould growing on the bacteria, but a clear zone around the mould. Fleming understood the importance of what had happened and immediately began to study the phenomenon.

He placed some mould on other plates and grew more colonies. By means of numerous experiments on animals he determined that this new substance was not toxic to the tissues and stopped the growth of the most common pathogenic bacteria.

Fleming called this substance penicillin. It is of the same family of moulds that often appear on dry bread.

But many investigations had been carried out before a method of extracting pure penicillin was found. It was also very difficult for Fleming to interest biologists and mould experts in penicillin and to decide the problem of its production.

In 1942 Fleming tried his own first experiment. A friend of his was very ill, dying. After several injections of penicillin the man was cured. It marked the beginning of penicillin treatment.

However, it was not until World War II that penicillin, the first antibiotic, was finally isolated by Howard Florey and Ernst Chain. Fleming, Florey and Chain received the Nobel Prize in Medicine in 1945, for their discovery which revolutionized medicine and led to the development of lifesaving antibiotics.

Fleming wrote numerous papers on bacteriology, immunology and chemotherapy. He was elected professor of the medical school in 1928 and emeritus professor of bacteriology at the University of London in 1948. He was elected fellow of the Royal Society in 1943 and knighted in 1944. He said: “Everywhere I go people thank me for saving their lives. I do not know why they do it. I didn't do anything. Nature makes penicillin. I only found it.”

Fleming died on 11 March 1955.
