CARDENAS, Denny et al. Frequency of anti Toxoplasma gondii antibodies in pregnant of Cucuta, Colombia. Rev Med Hered [online]. 2015, vol.26, n.4, pp.230-237. ISSN 1018-130X.

Toxoplasmosis is caused by Toxoplasma gondii and it is especially dangerous during pregnancy. The presence of IgG antibodies against T. gondii indicates past infection, while the presence of IgM indicates acute infection. Objective: To determine the frequency and titers of antibodies against T. gondii in pregnant women in Cucuta, Colombia. Methods: A cross sectional study was carried out in which titers of IgG and IgM to T. gondii were measured using agglutination and immunoassay methods in serum samples of first, second and third trimester pregnant women who attended pre-natal control in the Center for Imagenology and Clinical Laboratory during the second semester of 2014. Results: 167 women were evaluated; 115 (68.9%) were negative for IgG and 52 (31.1%) were positive; specific IgM was search for in 35 of these IgG positive women, only one was positive (3%). IgG titers varied from 1:1 to 1:8 in the 34 IgM seronegative women, but was 1:16 in seropositive women. Conclusions: One third of the population studied was previously infected showing low titers of IgG, the minority showed evidence of acute infection.
