Streptococcus dysgalactiae has two main subspecies: S. dysgalactiae subsp. equisimilis (SDSE) and S. dysgalactiae subsp. dysgalactiae (SDSD). SDSE often colonizes and causes infections in humans; however, SDSD is an animal pathogen which often causes pyogenic infection in domestic animals. We present a case of meningitis with SDSD and herpes simplex virus in a 22-day-old newborn baby who had no exposure to animals.
