“…In the current study, 10.57% of the animals were seroreactive in IIF, similar to the results found by Moura et al (2016) in Santa Catarina (SC) and Valença et al (2015) in Alagoas (AL), with a prevalence of 10.40% and 14.30%, respectively. In the literature, there are also reports of higher prevalence in Minas Gerais (MG) (GENNARI et al, 2015) and Italy (PAPINI et al, 2015).…”

“…Different diagnostic techniques, cut-off values, geographic locations, and management conditions may partially explain some of the differences in prevalence found in the literature (FINGER et al, 2013;VENTURI et al, 2017). In the present study, a IIF antibody titer cut-off value of 64 was considered an infection, which is consistent with previous studies (GENNARI et al, 2015;MOURA et al, 2016;PAPINI et al, 2015;VALENÇA et al, 2015). This value guarantees greater specificity, in addition to decreasing the possibility of cross-reactions with other etiological agents (ABREU, 2013).…”

“…Although horses are among the domestic species most resistant to Toxoplasma gondii, recent studies show an increase in infections in the recent years, with a significant and widespread prevalence, varying between 10% and 28% throughout the country (GENNARI et al, 2015;MOURA et al, 2016;VALENÇA et al, 2015). Regarding the 87 rural properties in this study, 25 (28.73%) had at least one animal reactive against toxoplasmosis by IIF, a value below that found by Valença et al (2015) in Alagoas (AL), where 69.40% of the studied properties had MAT-reactive animals.…”

Leptospirosis and toxoplasmosis are diseases that may affect man and domestic and wild animals. They also have wide geographical distributions and thus cause large public health issues. The objective of the current study was to conduct leptospirosis and toxoplasmosis seroepidemiology in horses used for animal traction in small rural propertiesof the municipality of Umuarama, in northwest region of the state of Paraná, Brazil. Blood samples were collected from 312 horses from 87 small farms. Microscopic agglutination tests (MAT) and indirect immunofluorescence (IIF) analysis were performed on sera to detect leptospirosis and toxoplasmosis, respectively. These were performed in conjunction with an epidemiological questionnaire. The MAT results included 180 (57.69%) samples that were considered reactive with titers between 100 and 12800 for one or more serovars. Thirty-three (10.57%) samples subjected to IIF were considered reactive, with titers ranging between 64 and 1024. From the analyzed variables, contact with wild animals (p= 0.012) and animal exchange between properties (p = 0.004) were associated with toxoplasma infection. The study revealed that horses in the northwestern region of Paraná were exposed to Leptospira spp. and Toxoplasma gondii, with an insignificant implication of the animals' clinical condition; however, since it is possible for animals to transmit infection to other animals as well as humans via the intermittent shedding of leptospires through urine into the environment, it may be considered a problem of one health. As for the presence of T. gondii antibodies, these horses played the role of sentinel of the infection. Environmental sanitation measures, serological studies of herds, control of rodents and felids on properties, and the dissemination of information about these diseases are relevant for disease control at the study site.A leptospirose e a toxoplasmose são enfermidades de ampla distribuição geográfica e podem acometer o homem, animais domésticos e selvagens que causam elevados problemas para a saúde pública. O objetivo deste trabalho foi realizar a soroepidemiologia da leptospirose e toxoplasmose em equinos utilizados como tração animal de pequenas propriedades rurais do município de Umuarama, região noroeste do estado do Paraná, Brasil. Foram coletadas amostras de sangue de 312 equinos de 87 pequenas propriedades rurais. Para detectar a leptospirose e toxoplasmose os soros foram submetidos às técnicas de soroaglutinação microscópica (SAM) e imunofluorescencia indireta (IFI) respectivamente associada ao preenchimento de um questionário epidemiológico. Na SAM, 180 (57,69%) amostras foram consideradas reagentes apresentando títulos entre 100 e 12800, para um ou mais sorovares. Na IFI, 33 (10,57%) amostras foram consideradas reagentes com títulos de 64 a 1024. Em relação às variáveis analisadas, o contato com animais selvagens (p= 0,012) e troca de animais entre propriedades (p= 0,004) foram associados à infecção toxoplásmica. O estudo revela que os equinos da região noroeste do Pa...

“…Entre as espécies domésticas, os equinos são os mais resistentes à infecção por T. gondii, podendo causar encefalite (Coiro et al 2012) além de sinais como hiperirritabilidade, incoordenação, desordens oculares e aborto que podem ser observados (Moura et al 2016).…”

RESUMO.-Este estudo teve como objetivo determinar a soroprevalência da toxoplasmose em equídeos mantidos em diferentes formas de manejo no estado de Pernambuco. Para tanto, um total de 400 amostras de soro sanguíneo de equídeos clinicamente saudáveis foram analisados através do teste de aglutinação modificado (MAT) considerando-se cut-off de 1:25. Dados referentes às características dos animais e dos rebanhos, sistema de criação, presença de outros animais, idade, sexo, raça, aptidão, condição física foram coletados por meio de questionários investigativos. Anticorpos IgG anti-Toxoplasma gondii foram detectados em 12,5% (50/400) dos animais analisados. Dos 12 municípios estudados, houve positividade em 91,67% (11/12) com variação entre 4,4% e 33,3%. Quando avaliados os fatores de risco, apenas o fator mesorregião (p=0,029) apresentou associação com a infecção, particularmente Zona da Mata (OR=3), seguida de Região Metropolitana do Recife (OR=2,2), Agreste (OR=1,7) e Sertão (OR=1). Os resultados revelam a presença do parasito na área estudada, o que pode representar um elo na cadeia de transmissão da toxoplasmose a qual tem repercussão em saúde pública tendo em vista que o Brasil é o oitavo maior exportador de carne equina do mundo. This paper reports seroprevalence of toxoplasmosis in horses kept in different forms of breeding system in the state of Pernambuco. For that, 400 blood serum samples from clinically healthy horses were analyzed through the test of modified agglutination (MAT) considering cut-off of 1:25. Data related to the characteristics of the animals and herds, breeding system, presence of other animals, age, gender, breed, aptitude, and physical conditions were collected throughout investigative surveys. IgG anti-Toxoplasma gondii antibodies were detected in 12.5% (50/400) of the analyzed animals. In the 12 studied towns, there was a positivity in 91. 67% (11/12) with a variation between 4% and 33.3%. When the risk factors were evaluated, only the mesoregion factor (p=0.029) had an association with the infection, particularly the Zona da Mata region (OR=3), followed by the Recife Metropolitan Area (OR=2.2), Agreste region (OR=1.7) and Sertão region (OR=1). The results shows the presence of the parasites on the studied area, which may represent a link with the transmission chain of toxoplasmosis which has influence on the public health system, considering that Brazil is the eighth greatest exporter of equine meat in the world.

“…O gênero dos equídeos não influenciou estatisticamente a soro positividade, assim como o observado em outros estudos (MENDONÇA et al, 2001;CAMOSSI et al, 2010;MOURA et al, 2016;LOPES et al, 2013;MIAO et al, 2013;e FINGER et al, 2013). Em contrapartida Oliveira et al (2014) e Haridy et al (2009) consideraram-no como um fator predisponente, sendo as fêmeas mais sensíveis a infecção pelo parasita do que os machos, possivelmente devido a fatores hormonais.…”
