'Seroprevalence and Molecular Detection of Toxoplasma gondii Infection among chicken (Gallus domesticus) in Riyadh Region, Saudi Arabia.
Abstract
Toxoplasmosis is a widely prevalent zoonotic disease. The prevalence of Toxoplasma gondii (T.
gondii)infection in chicken is a good indicator of soil contamination with T.gondiioocysts. Since
chicken meat is widely consumed in many countries including Saudi Arabia, in the present report, the prevalence of T.gondii infection in chicken (Gallus domesticus) in Riyadh region, Saudi Arabia was investigated, moreover, the T.gondii recent infection was determined using PCR test. T.gondiiSeroprevalence was studied in 200 chicken (Gallus domesticus) collected from different regions in Riyadh using ELISA IgG assay. The results revealed that 32% (64 out of 200) of the chicken investigated were seropositive. PCR test on the T.gondii B1 gene showed that 37.5% of the chicken had T.gondii DNA indicating recent infection. We concluded that, T. gondii infection may pose a potential threat to human and animal health in Riyadh region and attention should be given.
