Key points
- ÐÇ¿ÕÓéÀÖ¹ÙÍø's Streptococcus Laboratory works on streptococci and other Gram-positive catalase-negative cocci.
- The laboratory is a reference center that supports U.S. health departments and collaborates with many international partners.
- ÐÇ¿ÕÓéÀÖ¹ÙÍø laboratorians can assist health departments and public health laboratory workers upon request.

Priorities
Key activities for ÐÇ¿ÕÓéÀÖ¹ÙÍø's Streptococcus Laboratory include:
- Supporting active population-based surveillance for invasive disease
- Helping U.S. laboratories, including in response to outbreaks
- Building international laboratory capacity
- Researching special topics
Surveillance
Related to its pathogens, the laboratory supports Active Bacterial Core surveillance (ABCs) by performing whole-genome sequence-based typing and characterization of isolates. This work includes:
- Serotyping or emm typing
- Antimicrobial susceptibility testing
- Strain characterization
Laboratory support
ÐÇ¿ÕÓéÀÖ¹ÙÍø's Streptococcus Laboratory supports public health departments and laboratories upon request. The laboratory can type and characterize isolates that meet certain criteria.
ÐÇ¿ÕÓéÀÖ¹ÙÍø can also provide training to public health laboratory staff interested in developing typing capacity using one of the following approaches:
- Polymerase chain reaction
- Whole-genome sequencing
