“…Although these variables are related, the analysis was performed independently, since there were 49 dogs that although domiciled, had contact with stray dogs in the backyard of their houses. The lower prevalence in dogs at less than one year of age may be associated with shorter length of exposure to sources of T.gondii infection, as referred by several authors worldwide (5,24,27,(30)(31)(32) .…”

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.

Neospora caninum is protozoan parasite with domestic and wild dogs, coyotes and grey wolves as the definitive hosts and many warm-blooded animals as intermediate hosts. It was cultivated and named in 1988. Neosporosis is a major disease of cattle and has no public health significance. Since 1990's N. caninum has emerged as a major cause of abortion in cattle worldwide, including in Brazil. N. caninum also causes clinical infections in several other animal species. Considerable progress has been made in understanding the biology of N. caninum and there are more than 200 papers on this subject from Brazil. However, most of the reports on neosporosis from Brazil are serological surveys. Overall, little is known of clinical neosporosis in Brazil, particularly cattle. The few reports pertain to sporadic cases of abortion with no information on epidemics or storms of abortion. The objective of the present review is to summarize all reports from Brazil and suggest topic for further research, including prevalence of N. caninum oocysts in soil or in canine feces, and determining if there are additional definitive hosts, other than the domestic dog. There is need for a national survey in cattle using defined parameters. Future researches should focus on molecular characterization of N. caninum strains, possibility of vaccine production and relationship between wildlife and livestock epidemiology.Keywords: Neospora caninum, neosporosis, domestic animals, wild animals, Brazil. ResumoNeospora caninum é um protozoário parasita que possui os canídeos domésticos e selvagens, coiotes e lobos cinzentos como hospedeiros definitivos e vários animais de sangue quente como hospedeiros intermediários. Foi cultivado e nomeado em 1988. A neosporose é uma das principais doenças em bovinos e não tem significância em saúde pública. Desde 1990, N. caninum tem emergido como uma das principais causas de aborto em bovinos em todo o mundo, inclusive no Brasil. N. caninum também causa infecções clínicas em várias outras espécies animais. Consideráveis avanços foram feitos na compreensão da biologia desse parasita e há mais de 200 trabalhos sobre o assunto no Brasil. No entanto, a maioria dos relatos de neosporose do Brasil são relacionados a sorologia. Em geral, pouco se sabe sobre a neosporose clínica no Brasil, particularmente em bovinos. Os poucos relatos referem-se a casos esporádicos de aborto sem informações sobre epidemias ou surtos de aborto. O objetivo da presente revisão é resumir todos os relatos sobre N. caninum no Brasil e sugerir tópicos para pesquisas futuras, incluindo a prevalência de oocistos de N. caninum no solo ou em fezes caninas e determinar se há hospedeiros definitivos adicionais, exceto o cão doméstico no país. Uma pesquisa nacional em bovinos usando parâmetros definidos seria de grande importância. Pesquisas futuras deveriam ser focadas na caracterização de cepas de N. caninum, possibilidade de produção de vacinas e a relação epidemiológica entre a vida selvagem e o gado.Palavras-chave: Neospora caninum, neospo...
