Notes:
- The phylogenomic assignment score of this taxon is 0.10780 (N = 3).
- According to Bartlett et al. (2022), this species is an established human pathogen. Publication: Bartlett A, Padfield D, Lear L, Bendall R, Vos M. A comprehensive list of bacterial pathogens infecting humans. Microbiology 2022; 168:0.
- 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. Publication: Schlegel L, Grimont F, Ageron E, Grimont PA, Bouvet A.
