There is a lack of information concerning the prevalence Toxoplasma gondii infection in wild birds Mexico. In present study, serum samples and tissues from 653 Durango State, Mexico, were evaluated for T. infection. Antibodies to (modified agglutination test, titer 1∶25 or higher) found 17 (2.6%) birds, including 1 2 curve-billed thrashers (Toxostoma curvirostre), (1 Anas platyrhynchos, diazi) 4 ducks, eagles (Aquila sp.), 5 (27.8%) 18 great-tailed grackles (Quiscalus mexicanus), 7 (1.3%) 521 rock pigeons (Columba livia), (14.3%) quail (Coturnix coturnix). The seroprevalence captured park outside city zoo (11.6%, 8/69) was significantly higher than that other regions (1.5%, 9/584, OR = 8.38; 95% CI: 2.82–24.77; P 0.0001). Brains hearts 23 (17 seropositive, 6 seronegative) bioassayed mice isolation gondii. Viable isolated seropositive pigeons. DNA obtained isolate pigeon genotyped using PCR-RFLP typing 11 markers (B1, SAG1, SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1, Apico) revealed an atypical genotype.
