“…This result is similar when compared to the results found in Rolândia (PR) and Londrina (PR), with pregnant women between 36 and 45 years old, and between 31 and 48 years old, respectively (Lopes et al, 2009;Dias et al, 2011). In two maternity wards in Cuiabá (MT), an association between age and seropositivity was found (Leão et al, 2004).…”

“…In this paper, the prevalence for IgM anti-T. gondii antibodies was 1.0%, a lower result than that found in researches conducted in Palotina (PR) (Bittencourt et al, 2012), Vitória (ES) (Areal and Miranda, 2008), Londrina (PR) (Mandai et al, 2007), Rolândia (PR) (Dias et al, 2011), Miracema (RJ) (Ribeiro et al, 2008) and Recife (PE) (Porto et al, 2008), which detected 1.1%, 1.3%, 1.7%, 1.9%, 2.0%, and 2.8%, respectively. In the state of Santa Catarina (Sandrin et al, 2012), researchers have found a prevalence of 0.57%.…”

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.

Toxoplasmosis is a worldwide zoonosis with important public health implications. The aims of this study were to determine and identify factors associated to the seroprevalence of anti-Toxoplasma gondii antibodies in humans and dogs from Jataizinho, Parana State, Brazil. Serum samples from 280 humans and 766 dogs, from rural and urban areas, were tested by indirect immunofluorescent antibody test. Positive dilutions were ≥ 1:16. Epidemiological informations were obtained through an individual questionnaire and data tabulation was performed using EpiInfo 3.5.3 (CDC, Atlanta). Statistical significance was evaluated by chi-square (ᵪ 2 ) or Fisher's exact tests with a 5.0 % significance level. The seroprevalence in humans was 70.00% (196/280), as follows: 69.08% (143/207) in rural and 72.60% (53/73) in a slum urban community. The seroprevalence in dogs was 52.35% (401/766), as follows: 71.74% (99/138) in rural and 48.08% (302/628) in urban area. In rural areas, there was no factor associated to risk of infection. In urban slum community, visualizing more than four rats at home was a factor statistically associated to seropositivity for human toxoplamosis. Infection of urban dogs was associated to age, contact with stray dogs or rodents, and free access to street. The results indicated a similar possibility of contact with Toxoplasma gondii between dogs and humans living in rural or slum urban areas of small municipalities.Keywords: IFAT; prevalence; Toxoplasma gondii; zoonosis.

Os objetivos deste estudo foram determinar e identificar fatores associados à soroprevalência de anticorpos anti-Toxoplasma gondii em humanos e cães de Jataizinho, Paraná, Brasil. Amostras de soro de 280 humanos e 766 cães, de áreas rural e urbana, foram testadas pela reação de imunofluorescência indireta (RIFI). Foram consideradas positivas diluições ≥1:16. Informações epidemiológicas foram obtidas por meio de questionário individual e a tabulação dos dados foi realizada com EpiInfo 3.5.3 (CDC, Atlanta). A significância estatística foi avaliada por Chi-quadrado (ᵪ 2 ) ou Exato de Fisher com nível de significância de 5,0 %. A soroprevalência em humanos foi como segue: 70,00% (196/280), 69,08% (143/207) em área rural e 72,60% (53/73) em uma comunidade urbana carente. Em cães, foi 52,35% (401/766), na área rural 71,74% (99/138) e na área urbana 48,08% (302/628). Nas áreas rurais não houve fator estatisticamente associado ao risco de toxoplasmose. Na área urbana, visualizar mais do que quatro ratos em casa foi fator associado à soropositividade para toxoplasmose em humanos. A soropositividade em cães urbanos apresentou associação à idade, ao contato com cães errantes ou roedores e com acesso livre à rua. Os resultados indicaram semelhante possibilidade de contato com Toxoplasma gondii entre cães e humanos residentes em áreas rura...
