Streptococcus peroris sp. nov. and Streptococcus infantis sp. nov., new members of the Streptococcus mitis group, isolated from human clinical specimens. 1998 48 3 921 927 International Journal of Systematic Bacteriology Int J Syst Bacteriol 0020-7713 10.1099/00207713-48-3-921 9734047 From Mogens Kilian (e-mail, Jan 16 2016): Strain SK959 was derived from strain GTC849, which I received from the authors describing the species and designating that strain as the type strain. SK959 is my collection number making it clear that the strain has been passed through different laboratories before lyophilization and, as a consequence, may have some mutations that distinguish it from the original and from the other derivative ATCC 700779.
