Abstract
Toxoplasma gondii infection in pigs has epidemiological concern for its contributing role in human infections We determined seroprevalence of T gondii infection in 402 domestic pigs raised in backyards in Veracruz State Mexico using the modified agglutination test MAT cut off 125 182 453 of the 402 pigs were seropositive with MAT titers of 125 in 28 150 in 22 1100 in 18 1200 in 30 1400 in 35 1800 in 23 11600 in 11 and 13200 or higher in 15 Seropositive pigs were found in 137 533 of 257 homes in all 7 municipalities surveyed Multivariate analysis showed that T gondii seropositivity in pigs was associated with tropicalhumid climate OR = 432 95 CI 147–1262 P = 0007 of the raising municipalities feeding with leftovers OR = 283 95 CI 101–791 P = 004 storing pig food in the owner’s home OR = 239 95 CI 109–522 P = 002 and free ranging OR = 348 95 CI 149–815 P = 0003 Results indicate that backyard pigs in Veracruz have the highest seroprevalence of T gondii infection obtained by MAT in pigs studied in Mexico so far The correlates of T gondii infection found in the present study may be useful for an optimal planning of preventive measures against T gondii infection in pigs Results also remark the risk of T gondii infection in humans by ingestion of raw or undercook pork in Mexico
