Streptococcus equi subsp. equi RealPCRTest with Culture

Reduce the time needed to identify and isolate contagious horses or asymptomatic horses shedding intermittently


Our highly specific and sensitive Streptococcus equi subsp. equi polymerase chain reaction (PCR) test helps detect the presence of S. equi subsp. equi DNA.

Plus, we automatically provide a culture (organism ID only) of beta hemolytic Streptococcus organisms to allow for confirmation of a positive PCR result.

(Positives must be considered presumptive until confirmed by culture because PCR cannot distinguish between dead and live organisms).

It’s the only protocol available that provides confirmation to support a confident diagnosis.

Sample requirements

Collect nasal or guttural pouch washes in buffered saline into a sterile, screw-top container. Or submit nasal swabs in transport media without charcoal.

Turnaround times

The S. equi subsp. equi RealPCR Test with Culture is performed daily, Monday–Friday.

  • RealPCR results are available in 1–3 working days.
  • Culture identification test results are available within 72 hours of sample receipt.
