Other Streptococcus Species and Related Genera Activities

Key points

  • CDC's Streptococcus Laboratory works with S. salivarius, S. suis, and other streptococci beyond S. agalactiae, S. pneumoniae, and S. pyogenes.
  • The laboratory also works with other gram-positive, catalase-negative cocci.
  • Public health laboratories can contact the lab for information about identifying these types of bacteria.

Background

The Streptococcus Laboratory identifies and characterizes isolates of Streptococcus species and related genera (catalase-negative, gram-positive cocci). These include:

  • Abiotrophia, Aerococcus, Alloiococcus
  • Dolosicoccus, Dolosigranulum
  • Enterococcus, Eremococcus, Facklamia
  • Gemella, Globicatella, Granulicatella
  • Helcococcus, Ignavigranulum, Isobaculum
  • Lactococcus, Leuconostoc, Pediococcus
  • Tetragenococcus, Vagococcus, Weissella

Following in-house validation, laboratories can use real-time polymerase chain reaction (PCR) assays to target the gtfP and fbpS genes to detect S. salivarius and S. suis, respectively. View a list of primer and probe sequences:
