Streptococcus canis is a group G beta-hemolytic species of Streptococcus. [1] It was first isolated in dogs, giving the bacterium its name. These bacteria are characteristically different from Streptococcus dysgalactiae, which is a human-specific group G species that has a different phenotypic chemical composition.
Beyond the pain and discomfort associated with strep throat, one of the most frustrating aspects of the infection is that, to many people, it looks very similar to a sore throat. This is one ...
