Soroprevalência para Toxoplasma gondii em gestantes e neonatos atendidos em Hospital Universitário da região Sul do Brasil

Abstract

Toxoplasmosis is a parasitic zoonosis of worldwide distribution, caused by the protozoan Toxoplasma gondii. The aim of this study was to investigate the prevalence of antibodies against Toxoplasma gondii in pregnant women and neonates attended at a university hospital in southern Brazil. In serology for T. gondii by indirect immunofluorescence, was recorded prevalence among pregnant women from 42% (100/238) and 5% (12/238) for IgG and IgM, respectively. The IgG titer more common in pregnant women was 32 (32-1054). Congenital infection was not recorded, since the samples of umbilical cord serum were negative for IgM-specific. In multivariate analysis, was observed higher seroprevalence in pregnant women with aged equal or higher than 35 years (p=0.029). It is concluded that seropositivity recorded shows exposure of pregnant women to the parasite T. gondii. Despite not having been registered congenital infection, exposure of pregnant women demonstrates the need for attention to the diagnosis in prenatal testing.
