Strain

A strain is a pure culture of microorganisms or viruses of a certain species, isolated from one source and possessing any specific properties that distinguish it from other representatives of the same species.

Strains of one type of microorganism can differ in many ways - biochemical activity, pathogenicity, resistance to antibiotics and other drugs. For example, among Escherichia coli there are strains that cause food poisoning and harmless strains that are representatives of normal intestinal microflora.

Isolation of pure strains is of great importance in microbiology and medicine. Studying the properties of individual strains allows us to better understand the characteristics of this type of microorganism as a whole. Pure strains are used to produce vaccines, antibiotics, probiotics and other biotechnological processes.



A strain of microorganisms is a pure culture of bacteria or viruses of the same species, isolated from the same source. Strains of microorganisms have their own unique properties that distinguish them from other representatives of the same species. These properties may include size, shape, color, ability to grow in a particular environment, and other characteristics.

Strains are used in various fields of science and industry, for example, in medicine to create antibiotics, in the food industry to produce food, and in agriculture to protect plants from diseases.

To create a strain of microorganisms, a pure culture must be isolated from a single source, such as soil, water, or another organism. This crop is then grown in a specific medium until it reaches a certain size and shape. After this, you can analyze the properties of the resulting strain.

One of the advantages of using microbial strains is that they can be used to create new products and processes. For example, strains of bacteria can be used to produce antibiotics, and strains of viruses can be used to create vaccines.

However, when using strains of microorganisms, it is necessary to take into account their properties and possible side effects. Therefore, before using a strain, it is necessary to conduct a thorough analysis of its properties and possible risks.



A strain is a large collection of organisms of the same species. They differ from each other in certain characteristics, such as size, color, shape, vitality, and so on. In other words, strains have their own characteristics that help them survive in a certain environment. However, it is important to understand that not all microorganisms in the body are strains. Microorganisms that are not strains can have different characteristics and work in different situations.

Strains are important for medicine. Thanks to knowledge about the properties of strains, microbiology can control the epidemiological situation in the human body.
