Equine Strangles Cases and Diagnostic Testing at WSVL

To date in 2026, the Wyoming State Veterinary Laboratory (WSVL) has detected 12 cases of equine strangles.

Strangles is a highly contagious bacterial disease of the equine upper respiratory tract. The bacteria cross mucous membranes in the nose and mouth to infect lymph nodes, where they cause abscesses that can eventually rupture. The infected lymph nodes become swollen, which can compress the upper respiratory tract (hence, the name strangles). Younger horses often exhibit more clinical signs than older horses. The prognosis for uncomplicated horses is generally good. The best strategy to prevent strangles is to minimize exposure risks.

The WSVL Bacteriology Section offers the following diagnostic tests for Streptococcus equi subsp. equi:

· qPCR (new assay): $45 — results available within 24 hours

· Bacterial culture: $20 — results available in 2 days

· Antimicrobial susceptibility testing (performed on culture-positive isolates): $20 — results available in 3–4 days

For additional information, please contact the WSVL bacteriology section at 307-766-9931 or Dr. Mariela Srednik at 307-766-9932.

This map shows the geographic distribution of equine strangles cases submitted to the Wyoming State Veterinary Laboratory (WSVL) in 2026.

Note: Case locations are based on the owner's county when that information is provided on the submission form. If the owner's county is unavailable, the county of the submitting veterinarian is used.

Coming soon: a qPCR test for strangles (Streptococcus equi subsp. equi). The bacteriology section is currently validating this assay and look forward to offering it soon.
