Strangles is a prevalent infectious and contagious disease among Equidae that is caused by Streptococcus equi subspecies equi. This study was conducted on 184 horses that were studied in terms of carrying S. equi and its frequency among the horse population kept in equestrian clubs around Tabriz. The serum samples were collected from different equestrian clubs and were assayed using an iELISA (Indirect Enzyme-Linked Immunosorbent Assay) test for anti-SeM antibody in Streptococcus equi. The relative frequency of carriers was 53.3% in stallions and 24.5% in mares (p<0.001). The seroprevalence of carriers was 95% in horses with a record of respiratory disease and 39.6% in horses without respiratory disease (p<0.001). The seroprevalence of carriers was 68.2% in Kurd breed horses, 37.1% in the Arabian breed, 64% in crossbreed, and 80% in the Thoroughbred breed (p<0.05). Any significant relationship was not found between carriers and age (p>0.05). The results of Chi-squared test showed that the most positive results were observed in Arpadresi area of Tabriz city (p<0.001). The present investigation is the first study in the city of Tabriz, and the results show the lack of proper hygiene and the existence of stable carriers at the level of equestrian clubs.
