overall health status, and treatment administered [7]. T. equi is considered to be more pathogenic than B. caballi and is more frequently involved in clinical cases of EP [8]. This equine disease cannot be diagnosed based solely on clinical signs. Infections from B. caballi and T. equi are clinically indistinguishable; therefore, the differentiation between these infections is very important for successful treatment and ultimate control of the disease [9]. Horses infected with T. equi can become carriers and thus potentially disseminate the parasite to non-affected regions.
