Objective: To use two diagnostic antigens belonging to the frequently associated in Theileria domain, Theileria equi (T. equi) protein 82 (Te 82) and T. equi 104 kDa microneme-rhoptry antigen precursor (Te 43), to diagnose T. equi infection in horses as compared with equi merozoite antigen-2 (EMA-2). Methods: In the current study, we applied a cocktail-ELISA containing two antigens (EMA-2 + Te 82) to diagnose T. equi infection either in experimentally infected horses or in field infection. Results: Our findings have revealed that a cocktail formula of EMA-2 + Te 82 provided a more practical and sensitive diagnostic candidate for diagnosing T. equi infection in horses as compared with Te 82 or Te 43 alone. Conclusions: The ELISA technique using a cocktail formula of EMA-2 + Te 82 offers a practical and sensitive diagnostic tool for diagnosing T. equi infection in horses and using of this promising cocktail formula will be applicable for epidemiological surveys and will help control the infection in horses.
