The present study was conducted to investigate the prevalence of Toxoplasma gondii in sheep in Nepal. Blood samples were collected from 235 sheep from three districts of three different eco-zones namely, mountainous Jumla (88), hilly Pokhara (62) and plain/terai Chitwan (85). The samples were tested by using commercial ELISA kit. The overall prevalence of T. gondii infection in sheep was 36.17% (CI: 30.29–42.49%). The region wise prevalence showed highest in Chitwan (57.65%; CI: 47.04–67.60%), followed by Pokhara (32.94%; CI: 23.88–43.48%) and Jumla (9.41%; CI: 4.85–17.49%). Prevalence of T. gondii in Jumla was significantly lower than Pokhara and Chitwan (p < 0.05) but no significant difference in seroprevalence was encountered between Pokhara and Chitwan (p > 0.05). Similarly, no significant difference (p > 0.05) in prevalence of T. gondii was found in sex and age groups (p > 0.05). The result showed that T. gondii parasite is widely spread in the studied geographical regions of Nepal. Keywords: ELISA, Seroprevalence, Toxoplasma gondii, Nepal
