Seroepidemiology of Toxoplasma gondii Infection in Women of Reproductive Age: A Cross-Sectional Study in a Northwestern Mexican City

Research output: Contribution to journalArticlepeer-review


Background: Through a cross-sectional survey, we determined the
seroprevalence and correlates of Toxoplasma gondii (T. gondii) infection in women of reproductive age in Hermosillo City, Mexico.
Methods: We studied 445 women of reproductive age in Hermosillo
City in the northwestern Mexican state of Sonora. Women were enrolled in the University of Sonora. Sera of women were examined
for IgG and IgM antibodies to T. gondii by commercially available
enzyme immunoassays. The association of T. gondii seropositivity
with the characteristics of the pregnant women was determined by
bivariate and multivariate analyses.
Results: Of the 445 women (mean age: 22.18 ± 5.6 years) studied,
16 (3.6%) had IgG antibodies to T. gondii, and two (12.5%) were also
positive for IgM antibodies to T. gondii. Of the 16 anti-T. gondii IgGpositive women, six (37.5%) had IgG levels higher than 150 IU/mL,
four (25.0%) between 100 and 150 IU/mL, and six (37.5%) between
9 and 99 IU/mL. Multivariate analysis of socio-demographic and behavioral variables showed that T. gondii seropositivity was associated
with older age (odds ratio (OR): 5.30; 95% confidence interval (CI):
1.37 - 20.50; P = 0.01) and boar meat consumption (OR: 6.86; 95%
