Strain (biology), variants of plants, viruses or bacteria; or an inbred animal used for experimental purposes. Strain (chemistry), a chemical stress of a molecule. Strain (injury), an injury to a muscle (tear in tendon) in which the muscle fibers tear as a result of over-stretching.
1. a. : lineage, ancestry. b. : a group of presumed common ancestry with clear-cut physiological but usually not morphological distinctions. a high-yielding strain of winter wheat. broadly : a specified infraspecific group (such as a stock, line, or ecotype) c. : kind, sort.
In mechanics, strain is defined as relative deformation, compared to a reference position configuration. Different equivalent choices may be made for the expression of a strain field depending on whether it is defined with respect to the initial or the final configuration of the body and on whether the metric tensor or its dual is considered.

In biology, a strain is a genetic variant, a subtype or a culture within a biological species. Strains are often seen as inherently artificial concepts, characterized by a specific intent for genetic isolation.
