The Strain

The strain refers to a specific subtype or variation of a microorganism, such as a virus or bacteria. Think of it as a unique version within a broader category—similar to how different breeds of dogs are variations within the canine species. These strains can differ in how they behave, spread, or respond to treatments. Identifying the strain helps scientists and healthcare providers understand the nature of an infection and develop effective strategies to manage or prevent it. In essence, a strain is a distinct, identifiable form of a microorganism that impacts its characteristics and behavior.
