🧍 Because Streptococcus infantarius subsp. coli is not a valid name (lack of type strain) Streptococcus infantarius subsp. infantarius may be reduced to S. infantarius. — 🧍 Subsequently, this species has been divided into subspecies (see: below). — There are some problems with the two subspecies Streptococcus infantarius subsp. infantarius and Streptococcus infantarius subsp. coli (see: below). The author is very grateful to Dr. B.J. Tindall (DSMZ) for his helpful comments.
