“…Some studies have reported that stray dogs are more susceptible to T. gondii infection because of their increased likelihood to come into contact with rodents and the oocysts eliminated by cats (MINEO et al, 2004). However, in our study, we found no association between animals in the kennel and seropositivity to T. gondii (p>0.05), which is similar to the results observed by Azevedo et al (2005).…”

We examined the presence of antibodies against the parasites Toxoplasma gondii, Neospora caninum, and Leishmania spp., as well the presence of DNA from Leishmania spp., in dogs from Pirassununga -SP. The seropositivity rate was compared with the animals' originating location. Three hundred seventy-three blood samples from the county's kennel and local veterinary clinics were collected and analyzed. A total of 300 samples were tested for T. gondii and N. caninum using an indirect immunofluorescence antibody test (IFAT); 45% (135/300) were positive for T. gondii and 24.3% (73/300) were positive for N. caninum. Three hundred seventy-three samples were tested for Leishmania spp. using the IFAT. Of these, 4.6% (17/373) were positive. Additionally, 145 samples were tested using a polymerase chain reaction (PCR); of these samples, 0.7% (1/145) was positive. Considering the results, we conclude that these parasites are present in the city of Pirassununga -SP and that the animals have contact with the protozoan. It is therefore necessary to create methods for disease prevention to maintain both animal and human health in regard to leishmaniasis and toxoplasmosis.Keywords: IFAT, PCR, dogs, epidemiology, Leishmania spp., Neospora caninum, Toxoplasma gondii. ResumoAvaliou-se a presença de anticorpos contra Toxoplasma gondii, Neospora caninum e Leishmania spp.; assim como a presença de DNA de Leishmania spp. em cães de Pirassununga-SP, e associou-se sua soropositividade ao local de origem dos animais. Foram coletadas 373 amostras de sangue do canil municipal e de clínicas veterinárias locais, que foram analisadas pelo teste de Imunofluorescência Indireta (RIFI). Do total, 300 amostras foram testadas para T. gondii e N. caninum, das quais 45% (135/300) foram positivas para T. gondii e 24,3% (73/300) para N. caninum. Para Leishmania spp. foram avaliadas 373 amostras pela RIFI, sendo 4,6% (17/373) positivas. Adicionalmente, 145 amostras foram testadas utilizando-se a PCR e, dessas amostras, 0,7% (1/145) foi positiva. Considerando-se os resultados, pode-se concluir que esses parasitos estão presentes na cidade de Pirassununga -SP e que os animais tiveram contato com os protozoários. Faz-se, dessa forma, necessária a divulgação de meios de prevenção às doenças, com o intuito de manter o controle sobre as mesmas, tanto na saúde animal quanto na saúde humana, em relação à leishmaniose e à toxoplasmose.

“…Substantial differences between reagent dogs for T. gondii from distinct geographic urban areas were detected among the urban sectors of this research and in other studies in Brazil (6,29) . During the visits, deficient sanitation and infrastructure as well as garbage disposal on streets and squares were observed, and these facts could have improved transmission and development of the agent at the environment in districts D and E.…”

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...

Abstract:The aim of this study was to detect antibodies against T. gondii in dogs with clinical signs compatible with toxoplasmosis attended in a veterinary hospital. A serological survey was performed in 598 dogs from 1993 to 2013. The IgG antibodies survey against T. gondii was carried out by means of Indirect Fluorescence Antibodies Test (IFAT); samples with titers ≥16 were considered positive. Among the dogs with clinical signs, 259 (43,31%) were positive for T. gondii with titers varying between 16 to 4096; among the healthy animals, 79 (22.25%) were reagents. The most frequent signals were: neurological (30.43%) and uveitis (8.03%). Among variables race, gender, and age, only the last one affected the observed results with greater frequency f seropositive in elderly dogs. Keywords: clinical signs; dogs; IFAT; serology; Toxoplasma gondii; zoonosis.
