Streptococcus equi / Strangles

ID Screen® Streptococcus equi Indirect


Indirect ELISA kit for the detection of anti- Streptococcus equi in equine serum





  • Easy-to-use, standardized assay, with results in just over 2 hours
  • Qualitative protocol to detect previous exposure to S. equi
  • Quantitative protocol to assess SeM-specific antibody levels: horses with high SeM-specific serum antibodies may be predisposed to purpura when vaccinated for S. equi subsp equi with an attenuated live intranasal S. equi vaccine (1,2,3).
  • Practical: you can easily check that all samples have been correctly deposited because the dilution buffer changes color upon addition of the sera
