“…Infection with T. gondii can be transmitted vertically from mother to child, although a minority of infected individuals worldwide acquire the parasite congenitally 109 . Studies conducted in different countries in the Americas, Asia, Europe and Oceania over the past 40 years using varied methodologies present rates of primary infection during pregnancy that range from 1.0/1000 to 5.7/1000 pregnant women and do not suggest a temporal trend 110–119 . The risk of vertical transmission increases as pregnancy progresses, but infection acquired in the early stages of pregnancy is more likely to result in clinical disease.…”

Ocular toxoplasmosis results from retinal infection with the protozoan, Toxoplasma gondii. This parasite, which exists as multiple clonal subpopulations and in three stages, is capable of replication in any nucleated cell of its primary feline or multiple paratenic hosts. Human seroprevalence of toxoplasmosis is high across the globe, but with geographic variation. While prevalence of ocular toxoplasmosis is not well documented, toxoplasmic retinochoroiditis is the commonest form of posterior uveitis in many countries. Correlation of parasite genotype with disease is an important area of new research. Ocular infection with T. gondii often follows ingestion of bradyzoites in undercooked infected meat. Oocysts may survive for an extended period in the environment, and water contaminated with oocysts is an important source in toxoplasmosis epidemics. Ocular toxoplasmosis is preventable by a combination of community activities and personal measures. Public health action is well justified by the considerable burden of congenital and postnatal infections.

Seroprevalence of Toxoplasma gondii infection among immigrant and native pregnant women in Eastern Spain

et al. 2011

In European countries, toxoplasma antenatal screening is recommended to prevent toxoplasmosis. The seroprevalence of these infections in immigrants can be different than in native population. From February 2006 to June 2010, a cross-sectional study was carried out in all pregnant women attended at a reference unit in Elche, Spain. An enzyme immunoassay was used for detection of IgG antibodies against Toxoplasma gondii. For each immigrant woman, one Spanish pregnant woman of the same age cared for in the same day was recruited (Spanish control group). A total of 1,627 migrant pregnant women participated in this study. The adherence to screening among migrants was 91.9% (95% CI, 90.5-93.1%), similar than that found in Spaniards (92.2%; 95% CI, 90.8-93-4%). Among migrant women, 619 were positive for IgG anti-T. gondii antibodies (41.4%; 95% CI, 38.9-43.9%), compared with 12.0% (95% CI, 10.5-13.8%) among Spaniards (odds ratio (OR), 5.2 (95% CI, 4.3-6.3). Seroprevalence in pregnant women from Latin America, northern Africa, Eastern Europe, Africa Sub-Saharan and Western Europe was higher than in the Spanish control group (OR, 5.4, 5.8, 6.5, 5.4, and 2.4, respectively; p < 0.001). No Asian pregnant woman was immune. Seroprevalence increased with increasing age in migrant pregnant women: 15-25 years, 38.2%; 26-35 years, 40.7%; and 36-45 years, 52.8%. The seroprevalence of T. gondii infection in migrant pregnant women living in Spain was higher than in the native population. However, no cases were found in Asian immigrants, highlighting the importance of primary prevention of this infection in pregnant women coming from that geographic region.
