Strain

Introduction to the article Strains are diverse groups of microorganisms that have similar genetic origins and common properties. This means that strains can produce the same product (for example, bacteria that can produce milk) or exhibit certain properties (for example, strains that are resistant to antibiotics). Strains are often used in various fields of science, including biotechnology, agriculture and medicine. In this article we will look at how strains are used in these areas and what properties they acquire due to their genetic origin. We will also look at how strains can be manipulated and used to solve various problems.

Description of the concept of strains A strain is a group of microorganisms of the same species that has a certain genetic origin. If all organisms in a group have the same properties, then they are called genotypic strains. Genotypic strains are different from phenotypic strains, which carry different phenotypes but have the same genotype. Strains are divided into many different categories depending on what properties they have. For example, bacterial strains have the ability to produce a certain product or are resistant to certain antibiotics. Other categories of strains include thermotolerant strains (resistant to high temperatures), prion strains (ability to cause disease), etc. The properties of strains can be changed by mutations in their genome, however, this can lead to a decrease in the effectiveness of the strain or a decrease in its ability to produce the desired product. The strain genes that control these changes are called virulence genes. These genes may be useful for producing new drugs or fighting diseases. The management and use of strain characteristics are important aspects in modern science.
