Efecto de medidas preventivas contra la toxoplasmosis en embarazadas
Abstract
The incidence of Toxoplasma gondii infection was studied by the Parasitology Group of the Colombian National Institute of Health in sera from 1,000 pregnat women in prenatal control at the Caja Nacional de Previsión, from 1987 until 1990. Specific IgG antibodies against Toxoplasma gondii were measured by the indirect immunofluorescence technique. Fifty nine per cent (59%) of the women were positive with titres ranging between 1:16 to 1:4,096. This figure agrees with those of the First National Health Survey. Forty one per cent (41%) of the woman population was negative; none of the seronegative women seroconverted, yielding an incidence of O in the studied group. All pregnant women were instructed about preventive measures to avoid the T. gondii infection during pregnancy, which showed a high effectiveness, since none of the seronegative patients seroconverted during pregnancy. Thus, it is highly advisable, to give education about the ways to prevent the infection, in addition to the serological follow-up.
