Seroprevalence of Toxoplasma gondii in sheep from the Ancash region, Peru

The aim of this study was to determine the seroprevalence of Toxoplasma gondii in sheep from the Ancash region, Peru. In total, 199 serum samples were evaluated with a commercial indirect ELISA kit. The real seroprevalence of antibodies against T. gondii was 55.47% (95% CI: 55.14- 55.80). The province of Yungay had the highest frequency with 82.01% (95% CI: 80.78- 83.24), as well as animals that lived at <2500 m above the sea level with areal value of 76.11% (95% CI: 74.83- 77.39). A significant association was found with the variable altitude (OR = 2.96, p=0.016), where sheep living at altitudes <2500 m above sea level have a higher risk of contracting toxoplasmosis compared to those living at altitudes >2500 m above sea level. No significant association was found with the variables age and sex (p>0.05).
