Toxoplasmosis seroepidemiology in pregnant women in a city in the Northwest AbstractToxoplasmosis is a zoonosis caused by the Toxoplasma gondii protozoa. The congenital form happens when the parasite reaches the fetus through the placenta and causes damages of different intensities, which can be consequence of the strain virulence, of the immune response capability of the pregnant woman or even of the pregnancy stage, and can result in fetal death or severe clinical symptomatology. The aim of this paper was to determine the prevalence of antibodies to Toxoplasma gondii antibodies in pregnant woman seen at the Basic Health Units (BHU) in the city of Umuarama (PR) and check for possible toxoplasmosis associations with social-demographic characteristics, behavior and environmental variables. In this study, a total of 813 pregnant women who had their prenatal exams at the BHU in the city of Umuarama (PR) were included. Blood samples collected from these subjects were submitted to IgG and IgM anti-T. gondii antibody survey. Each pregnant woman answered an epidemiological questionnaire for the detection of variables, which were later analyzed by the EpiInfo program. The prevalence detected for IgG and IgM anti-T. gondii antibodies were 56.8% and 1.0%, respectively. The variables age group, education level, per capita income, number of pregnancies, ingestion of fresh sausage, presence of peridomiciliary cats in the backyard and the habit of ingesting farm milk showed association to the infection by T. gondii.Keywords: Toxoplasma gondii; serology; zoonosis; public health, congenital toxoplasmosis.

SUMMARYThe aim of the present work was to determine the prevalence of IgG and IgM anti-Toxoplasma gondii antibodies and the factors associated to the infection in pregnant women attended in Basic Health Units in Rolândia, Paraná, Brazil. The sample was divided in two groups: group I (320 pregnant women who were analyzed from July 2007 to February 2008) and group II (287 pregnant women who were analyzed from March to October 2008). In group I, it was found 53.1% of pregnant women with IgG reactive and IgM nonreactive, 1.9% with IgG and IgM reactive, 0.3% with IgG non-reactive and IgM reactive and 44.7% with IgG and IgM non-reactive. In group II, it was found 55.1% with IgG reactive and IgM non-reactive and 44.9% with IgG and IgM non-reactive. The variables associated to the presence of IgG antibodies were: residence in rural areas, pregnant women between 35-40 years old, low educational level, low family income, more than one pregnancy, drinking water which does not originate from the public water supply system and the habit of handling soil or sand. Guidance on primary prevention measures and the quarterly serological monitoring of the pregnant women in the risk group are important measures to prevent congenital toxoplasmosis.

“…Os gatos podem disseminar oocistos no ambiente, enquanto os cães podem atuar como vetores mecânicos auxiliando na transmissão das formas infectantes do T. gondii aderidas em seu pelo 33,34 . Em outros estudos 13,19 o contato com gatos não teve associação significativa com a infecção pelo T. gondii. Em contrapartida, Lopes et al 20 e Avelino et al 33 encontraram associação quanto à presença de gatos.…”

“…Valores semelhantes de prevalência de susceptibilidade foram encontrados Rio Grande do Sul (25,5%) 22 e em Recife (22,5%) 13 . A prevalência de infecção ativa para o T. gondii nas mulheres grávidas foi de 0,9%, achados similares foram evidenciados em Fortaleza, Ceará (0,5%) 15 e em Natal, Rio Grande do Norte (0,52%) 30 , que também estão no Nordeste do Brasil, e em Goiânia, Goiás (0,7%) 31 .…”

ResumoOBJETIVO: Determinar a prevalência de toxoplasmose e identificar os principais fatores associados à sororeatividade em gestantes atendidas em dois centros de referência em uma cidade do Nordeste do Brasil. MÉTODOS: Foi realizado um estudo transversal com 561 gestantes atendidas em dois centros de referência para pré-natal de alto risco em uma cidade do Nordeste do Brasil. Todas foram entrevistadas por meio de um questionário epidemiológico e foram coletadas amostras de sangue em que foram realizadas sorologia anti-Toxoplasma gondii para IgG e IgM (ELISA), teste de avidez da IgG e reação em cadeia da polimerase (PCR). A análise estatística foi realizada com o programa SPSS version 18.0 Windows, usando odds ratio e intervalo de confiança de 95%, considerando-se o nível de significância de 5%. RESULTADOS: Constatou-se sororeatividade para toxoplasmose em 437 (77,0%), susceptibilidade em 124 (22,1%) e 5 (0,9%) gestantes com infecção ativa. Não encontramos associação significativa entre sororeatividade para toxoplasmose e idade, procedência, renda, escolaridade, situação da rede de esgotos, número de gestações e idade gestacional. As variáveis com associação significativa (p≤0,05) para sororeatividade foram: multigestas (p=0,03) e convívio com cães soltos na rua (p=0,001). CONCLUSÕES: O estudo permitiu identificar uma alta sororeatividade para toxoplasmose entre as pacientes atendidas no pré-natal, assim como os fatores associados à sororeatividade, devendo ser reforçadas orientações apropriadas sobre medidas de prevenção primária e monitoramento sorológico trimestral das gestantes nesse município e outras regiões do Nordeste do Brasil. Abstract PURPOSE:To determine the prevalence of toxoplasmosis and to identify the main factors associated with seroreactivity in pregnant women cared for at two reference centers in a city in Northeast Brazil. METHODS: A cross-sectional study was conducted on 561 pregnant women at two high-risk prenatal reference centers in a city in Northeast Brazil. All women were interviewed using an epidemiological questionnaire and had their blood samples collected for the following serological tests: anti-Toxoplasma gondii IgG and IgM (ELISA), IgG avidity test, and polymerase chain reaction (PCR). Statistical analysis was carried out using SPSS version 18.0 for Windows, calculating odds ratio, confidence interval of 95% and with the level of significance set at 5%. RESULTS: Seroreactivity for toxoplasmosis was detected in 437 women (77.0%), susceptibility in 124 (22.1%) and active infection in 5 (0.9%). There was no significant association between seroreactivity for toxoplasmosis and age, location, income, education, availability of sewage, number of pregnancies or gestational age. The variables significantly associated (p≤0.05) with seroreactivity were multiparity (p=0.03) and living with stray dogs (p=0.01). CONCLUSIONS: This study identified high seroreactivity for toxoplasmosis among patients seen during prenatal care, as well as factors associated with seroreactivity. Appropriate guid...
