Incidence of anti-Toxoplasma antibodies in women with high-risk pregnancy and habitual abortions.
Toxoplasmosis is a zoonosis caused by Toxoplasma gondii, an obligate intracellular parasite. In pregnant women on the worldwide scale, there are seroprevalences from 7% to 51.3% and in women with abnormal pregnancies and abortions the seroprevalences vary from 17.5% to 52.3%. In Mexico, seropositivity has been found to vary from 18.2% to 44.8% in women with abnormal deliveries or abortions. This study's aim was to determine the incidence of IgG and IgM anti-Toxoplasma antibodies in women at the Gineco-Obstetrics Hospital of the Western Medical Center of the Mexican Social Security Institute. Three hundred and fifty women with high-risk pregnancies were studied, and 122 (34.9%) were found to be IgG seropositive and 76 (20.7%) were IgM positive. In one group of women with habitual abortions there were 48 (44.9%) with the presence of IgG antibodies and 33 (33.3%) were IgM seropositive. Seropositivity was analyzed according to age, occupation, socio-economic level, eating raw or poorly cooked meat, and living with cats.
