Strain (biology) - Wikipedia
WEBA strain is a genetic variant or subtype of a microorganism (e.g., a virus, bacterium or fungus). For example, a "flu strain" is a certain biological form of the influenza or "flu" virus. These flu strains are characterized by their differing isoforms of surface proteins.

WEBMany studies indicate that a bacterial species is composed of strains that are 70 to 100 percent related. In contrast, relatedness between different species is 0 to about 65 percent. It is important to emphasize that the term “related” does not …
Identifying Bacteria Through Look, Growth, Stain and Strain
WEBFeb 7, 2020 · Do they look slimy? Or wrinkly? As microbiologists combined different formulations of nutrients with agar to grow a diverse set of microorganisms, they created another tool for microbial identification: selective and differential media that help microbiologists identify bacteria and yeast species.

Bacterial taxonomy - Wikipedia
WEBBacterial taxonomy is the classification of strains within the domain Bacteria into hierarchies of similarity. This classification is similar to that of plants, mammals, and other taxonomies. However, biologists specializing in different areas have developed differing taxonomic conventions over time.
Diversity within species: interpreting strains in microbiomes
WEBSep 1, 2020 · For over a century, bacterial cultivation has enabled the isolation and classification of thousands of bacterial strains. Through these efforts, a species concept was translated in the bacterial context as a group of individuals that form a coherent genomic cluster 1 (see below for details and disagreements).
