| Abstract: | A total of 482 serum samples from pastoral camels in the Butana plains, mid-Eastern Sudan, were tested for Toxoplasma antibodies by the latex agglutination test (LAT). Sixty-seven percent of the camels were seroreactive. The prevalence rate of seroreactivity increased significantly with age (P less than 0.01) and was highest among camels aged over 7 years (74.2%). The prevalence rate of seropositivity decreased proportionally with the level of serum dilution. At dilutions of 1:32 and above, the prevalence rate was 25.9%. There were no sex-linked differences in seroreactivity. This study suggests widespread infection with Toxoplasma gondii among pastoral camels, a finding that warrants a closer look into the possible ways infection is acquired by camels in their arid environment, its economic impact, as well as its public health significance, especially among the nomads who consume cameline milk and liver raw. |
