MESSINA, Matías T et al. Prevalencia de anticuerpos anti-Toxoplasma gondii en embarazadas en siete hospitales de Buenos Aires: Comparació;n entre 2006 y 2017. Medicina (B. Aires) [online]. 2019, vol.79, n.6, pp.433-437. ISSN 0025-7680.

We analyzed the presence of IgG and IgM anti- Toxoplasma gondii, as a measure of infection, in pregnant women attending seven hospitals in the Metropolitan Area of Buenos Aires during 2006 and 2017. T. gondii seroprevalence in 2006 vs. 2017, was: Hospital Alemán: 22 and 17% (p = 0.004), Hospital Fiorito: 44 and 33% (p < 0.001), Hospital Gandulfo: 30 and 34% (p 0.025), Hospital Grierson 60 and 44% (p < 0.001), Hospital Rivadavia: 59 and 51% (p = 0.003), Hospital Sardá: 47 and 39% (p < 0. 001), and Hospital Thompson: 61 and 51% (p < 0.001). The comparison showed a significant decrease in seroprevalence in six hospitals. We also observed a significant decrease in the reactivity for IgM in 2017 compared to 2006 and in the seroprevalence for T. gondii in the overall population of pregnant women in the study. This means that a greater number of women are susceptible to develop acute infection during pregnancy.
