The reference used for compiling the methods in Section I is:
Murray, P.R., Baron, E. J., Jorgensen, J.J., Pfaller, M.A., and Yolken, R.H. Manual of Clinical Microbiology, 8th ed. ASM Press: Washington, DC, 2003.

The Streptococcus species identification methods in Section II were compiled by several individuals, including Lynn Shewmaker, Richard Facklam, and Lucia Teixeira.
