Etymology

The specific epithet hyovaginalis is derived from the Greek hŷs (genitive: hyos, "pig") and Latin vagina ("sheath" or "vagina"), combined with the suffix -alis (pertaining to). The name refers to its origin in the vaginal tract of pigs.^[2]

Isolation and ecology

Streptococcus hyovaginalis was originally isolated from vaginal swabs taken from sows in Belgium.^[1] It appears to be a rare or minor component of the porcine vaginal microbiota and has not been implicated in disease.
