Resumo: | The tick-borne diseases in addition to have a worldwide distribution, related to the dispersion of these vectors, and a complex epidemiologic network, making them difficult to control and prevention, cause major impacts on human and animal health. Brazil, the second largest herd of horses in the world, has the Theileria equi as a major hemoparasites transmitted by ticks to such animals, causing serious barriers to equideocultura in the country, which is considered endemic. Moreover, some aspects of its epidemiology, as the real vector of the disease in the country, are still not well understood. Regarding zoonotic diseases that the animals are involved, an emerging borreliosis, the Baggio - Yoshinari Syndrome, has drawn attention because horses seropositive for Borrelia spp. has been evidenced in our country, suggesting possible involvement of these animals in its epidemiology. Thus, this study aimed to perform serological diagnosis and assess the risk factors associated with seropositivity for Theileria equi and Borrelia spp. in the herd of horses for military use in the municipality of Resende, state of Rio de Janeiro. Samples of 174 horses for military use were tested by indirect ELISA immunoassay for Theileria equi and Borrelia burgdorferi strain G39/40. The dependent variable (seroreactivity) was tested through bivariate analysis for the association as the independent variables (gender, age, racial definition, group management, creation time in AMAN, system creation, origin of the horse, the presence of infestation by Dermacentor nitens, by Amblyomma cajennense, level of tick infestation and presence of tick infestation). The variables that were associated in bivariate analysis (p < 0.25) were included in the logistic regression model for multivariate analysis. It was found that the prevalence Borrelia spp. was 29.89%, and the T. equi prevalence was 74.14 %. Multivariate analysis demonstrated that the presence of tick infestation is associated (p < 0.05) with seropositivity for Borrelia spp. in horses (OR 3,45; CI 1,2 ? 9,7), and the creation time in AMAN greater than 15 years associated with seropositivity for T.equi (OR 5,70; CI 1,23 - 22,1). From the results obtained it can be inferred that ticks are related in the transmission of Borrelia spp in the herd studied, with their probable vectors. Further evidence of circulating Borrelia spp. in horses reinforces their role as sentinels, warning of the occurrence of human cases. Regarding Theileria equi, it was found that the area is endemic for the disease with a high prevalence of asymptomatic carriers, evoking care and preventive measures in the introduction of horses, coming from areas unaffected or enzootic instability, in the herd. |

O Brasil, com o terceiro maior rebanho de equ?deos do mundo, tem como um dos principais agentes transmitidos por carrapatos aos equ?deos Theileria equi. Tal agente ? considerado end?mico e vem causando entraves ? equideocultura nacional. Al?m disso, alguns aspectos de sua epidemiologia, como o artr?podo vetor da doen?a no pa?s, ainda n?o foram elucidados. No que tange ?s doen?as zoon?ticas em que os equ?deos est?o envolvidos, a S?ndrome de Baggio-Yoshinari, uma borreliose emergente, tem chamado a aten??o, pois t?m sido evidenciados equinos soropositivos para Borrelia spp. em nosso pa?s, sugerindo o envolvimento destes animais na epidemiologia desta doen?a. O objetivo deste estudo foi realizar o diagn?stico sorol?gico e avaliar os fatores de risco associados ? soropositividade para Theileria equi e para Borrelia spp. no rebanho de equinos de uso militar do munic?pio de Resende, estado do Rio de Janeiro. Amostras de 174 equinos de uso militar foram testadas atrav?s do ensaio de adsor??o imunoenzim?tica indireta iELISA para Theileria equi e Borrelia burgdorferi cepa G39/40. A vari?vel dependente (sororreatividade) foi testada, atrav?s de an?lise bivariada, quanto ? associa??o ?s vari?veis independentes (g?nero, idade, defini??o racial, grupo de manejo, tempo de cria??o na AMAN, sistema de cria??o, origem do equino, presen?a de infesta??o por Dermacentor nitens, presen?a de infesta??o por Amblyomma cajennense, grau de infesta??o por carrapatos, e presen?a de infesta??o por carrapatos). As vari?veis que apresentaram associa??o na an?lise bivariada (p<0,25), foram inclu?das no modelo de regress?o log?stica. Verificou-se que a soropreval?ncia para Borrelia spp. foi de 29,89%, e a para T. equi de 74,14%. A an?lise multivariada demonstrou que a presen?a de infesta??o de carrapatos est? associada (p<0,05) ? soropositividade dos equinos para Borrelia spp. (OR 3,45; IC 1,2 - 9,7), e que o tempo de cria??o na AMAN superior ? 15 anos est? associado ? soropositividade para T.equi (OR 5,70; IC 1,23 - 22,1). A partir dos resultados obtidos pode-se inferir que os carrapatos est?o relacionados na transmiss?o da Borrelia spp. no rebanho estudado, sendo seus prov?veis vetores. Al?m disto, a evid?ncia de circula??o de borr?lias nos equinos refor?a seu papel como sentinelas, alertando para a ocorr?ncia de casos humanos. Com rela??o ? Theileria equi, verificou-se que a ?rea ? end?mica para a doen?a, com alta preval?ncia de animais portadores assintom?ticos, evocando cuidados e medidas preventivas na introdu??o de equinos, oriundos de ?reas de instabilidade enzo?tica ou indenes, no rebanho.Submitted by Jorge Silva (jorgelmsilva@ufrrj.br) on 2020-02-14T18:30:40Z No. of bitstreams: 1 2014 - Rubens Fabiano Soares Prado.pdf: 2042043 bytes, checksum: 143c18335d78655e1170899efb5d0c6d (MD5)Made available in DSpace on 2020-02-14T18:30:40Z (GMT).

description |
The tick-borne diseases in addition to have a worldwide distribution, related to the dispersion of these vectors, and a complex epidemiologic network, making them difficult to control and prevention, cause major impacts on human and animal health. Brazil, the second largest herd of horses in the world, has the Theileria equi as a major hemoparasites transmitted by ticks to such animals, causing serious barriers to equideocultura in the country, which is considered endemic. Moreover, some aspects of its epidemiology, as the real vector of the disease in the country, are still not well understood. Regarding zoonotic diseases that the animals are involved, an emerging borreliosis, the Baggio - Yoshinari Syndrome, has drawn attention because horses seropositive for Borrelia spp. has been evidenced in our country, suggesting possible involvement of these animals in its epidemiology. Thus, this study aimed to perform serological diagnosis and assess the risk factors associated with seropositivity for Theileria equi and Borrelia spp. in the herd of horses for military use in the municipality of Resende, state of Rio de Janeiro. Samples of 174 horses for military use were tested by indirect ELISA immunoassay for Theileria equi and Borrelia burgdorferi strain G39/40. The dependent variable (seroreactivity) was tested through bivariate analysis for the association as the independent variables (gender, age, racial definition, group management, creation time in AMAN, system creation, origin of the horse, the presence of infestation by Dermacentor nitens, by Amblyomma cajennense, level of tick infestation and presence of tick infestation). The variables that were associated in bivariate analysis (p < 0.25) were included in the logistic regression model for multivariate analysis. It was found that the prevalence Borrelia spp. was 29.89%, and the T. equi prevalence was 74.14 %. Multivariate analysis demonstrated that the presence of tick infestation is associated (p < 0.05) with seropositivity for Borrelia spp. in horses (OR 3,45; CI 1,2 ? 9,7), and the creation time in AMAN greater than 15 years associated with seropositivity for T.equi (OR 5,70; CI 1,23 - 22,1). From the results obtained it can be inferred that ticks are related in the transmission of Borrelia spp in the herd studied, with their probable vectors. Further evidence of circulating Borrelia spp. in horses reinforces their role as sentinels, warning of the occurrence of human cases. Regarding Theileria equi, it was found that the area is endemic for the disease with a high prevalence of asymptomatic carriers, evoking care and preventive measures in the introduction of horses, coming from areas unaffected or enzootic instability, in the herd. |
