Abstract
Toxoplasma gondii is an obligatory intracellular parasite that can infect man and homoeothermic animals. In immunocompetent individuals the infection is generally asymptomatic, the foremost groups seriously affected by the infection are the immunocompromised and the pregnant women who acquire the infection during pregnancy. In this survey were analyzed 1485 serum samples from women attended at public health network of São Paulo metropolitan region during the period of January 2001 to July 2005. The detection of IgG antibody anti-T.gondii was realized by enzyme-linked immunosorbent assay (ELISA), both IgG and IgM antibodies were detected by immunofluorescent antibody technique (IFAT). Among the samples analyzed 57.10% presented IgG antibody anti-T. gondii and IgM antibody was detected in 1.95% individuals. Previous epidemiologic studies performed in Brazil demonstrated an IgG anti–T. gondii antibody seroprevalence varying from 40% to 80%, which corroborate with the date of the present investigation. There is the necessity of the studies to estimate the T. gondii infection prevalence rate in several Brazilian regions, in order to establish a developing health education strategies, and information programs for population to decreased congenital infection risk.References
