RESUMO
In this study, ELISA was used for the detection of antibodies against the immunodominant surface antigen 1 [SAG 1, synonymous P30] of Toxoplasma gondii and peroxidase-conjugated protein G was used instead of commercially unavailable enzyme-conjugated anti-dromedary antibody. A latex agglutination test was employed to select 20 seronegative control animals and peroxidase-conjugated protein A was used for comparison with protein G. The overall seroprevalence rate was 31.4%, males had, to some extent, a higher seropositive rate than females. Seropositive camels sampled in winter had significantly higher antibody levels than those sampled in summer. ELISA values using protein G and protein A conjugates were significantly correlated. The results were discussed
