One hundred and thirty Texel sheep and their 117 Texel lambs were included in the study. Serum samples were tested for antibodies to<jats:italic>T<\/jats:italic>.<jats:italic>gondii<\/jats:italic>,<jats:italic>N<\/jats:italic>.<jats:italic>caninum<\/jats:italic>and<jats:italic>Sarcocystis<\/jats:italic>spp. using IFAT.<jats:italic>Toxoplasma gondii<\/jats:italic>seroprevalence was 10.00% in sheep (IC<jats:sub>95%<\/jats:sub>: 4.80\u201315.20%), being higher in adult sheep (\u226512 year) than in younger sheep (OR 1.30; 95% CI, 1.10\u20131.50).<jats:italic>N<\/jats:italic>.<jats:italic>caninum<\/jats:italic>and<jats:italic>Sarcocystis<\/jats:italic>spp. seroprevalences were 1.54% (IC<jats:sub>95%<\/jats:sub>: 0.00\u20135.70) and 72.09% (IC<jats:sub>95%<\/jats:sub>: 67.70\u201382.70), respectively, with no association between age and seropositivity in sheep (<jats:italic>P<\/jats:italic>&gt;0.05).<jats:italic>T<\/jats:italic>.<jats:italic>gondii<\/jats:italic>seroprevalence in lambs was 4.27% (IC<jats:sub>95%<\/jats:sub>: 0.61\u20137.94). No association between<jats:italic>T<\/jats:italic>.<jats:italic>gondii<\/jats:italic>serological status in sheep and their lambs was detected (<jats:italic>P<\/jats:italic>= 0.07). Two<jats:italic>T<\/jats:italic>.<jats:italic>gondii<\/jats:italic>and<jats:italic>Sarcocystis<\/jats:italic>spp. seropositive lambs were euthanized and<jats:italic>T<\/jats:italic>.<jats:italic>gondii<\/jats:italic>and<jats:italic>Sarcocystis<\/jats:italic>spp. DNA was detected by PCR in their tissues. In conclusion, the increase of<jats:italic>T<\/jats:italic>.<jats:italic>gondii<\/jats:italic>seropositivity in relationship with sheep age and the lack of association between sheep-lamb serological status, suggest that horizontal infection is the main transmission route in this flock as reported before. Due to the low number of<jats:italic>N<\/jats:italic>.<jats:italic>caninum<\/jats:italic>-seropositive ewes no assumptions can be done about the impact of this parasite in this flock. According with previous reports, the main transmission route for<jats:italic>Sarcocystis<\/jats:italic>spp. in this species in the present study was
