Toxoplasmosis is caused by
Toxoplasma gondii, which is particularly relevant in
pregnant women, due to the
risk of
congenital infection. The aim of this study was to study the serological profile of
pregnant women and analyze some factors related to
infection in this group. A descriptive and
retrospective study was performed analyzing the results of 356
pregnant women in the Mixed
Health Unit of Jaçanã-RN from 2009 to 2014. Results of
serological tests for
IgG and
IgM anti-T. gondii
antibodies were provided by LACEN-RN. The
chi-square test (χ2) was calculated being considered statistically significant for p<0.05. The results showed that 59% of the
pregnant women tested presented
serology IgG anti-T. gondii
reagent (
IgG+) and
IgM anti-T. gondii non-reactive (
IgM-), 0.6%
reagent for both (
IgG+ and
IgM+) and 40.4% susceptible to
infection (
IgG- and
IgM-). 71.3% of the
women were tested in the
first trimester of
pregnancy; the 20-29 years of age range was the most prevalent (62.5%) and the 11-19 years of age range was the most susceptible (47%). The rural
women had the highest
incidence of positive
serology (60.2%) and those from the
urban area were the most susceptible (40.7%). There was no statistical
association between
serology and the
age group (p=0.282) and origin (p=0.881) variables. There is need for
investment in
prenatal care and
health education for the
population about
toxoplasmosis
