Resumo
A Piroplasmose Equina (PE) resulta da infeção por Babesia caballi e Theileria equi e é atualmente responsável por grandes perdas económicas mundiais. Quando um equino é exportado de Portugal para os EUA, deve fazer-se acompanhar da sua identificação, testes serológicos negativos e um certificado sanitário assinado pelo veterinário. Esta doença é endémica em regiões com climas tropicais, subtropicais e temperados. A maioria dos sinais clínicos derivam da anemia hemolítica associada a febre. O diagnóstico pode ser realizado através de exame microscópico de esfregaços sanguíneos, testes serológicos ou pelo teste de cadeia de polimerase em tempo real. Atualmente, o fármaco que apresenta uma maior eficácia no tratamento destas infeções é o dipropionato de imidocarb, no entanto, existem outros fármacos disponíveis. Este estudo teve como objetivo obter informação relevante sobre a incidência de piroplasmose em Portugal através da análise de testes serológicos realizados a 139 equinos entre 2020 e 2022, com o intuito de observar a distribuição de Piroplasmose em equinos Lusitanos em território nacional avaliados para exportação. O presente estudo constatou que apesar da obrigatoriedade de realizar o teste serológico de ELISA, a grande maioria dos casos positivos foram ao teste serológico de IFAT, nomeadamente 24,5%, existindo uma crescente incidência de Theileria equi em comparação com Babesia caballi, 68% e 20% respetivamente. Sendo o Alto Alentejo a zona com maior positividade de entre as nove regiões, nomeadamente 68,2%. São necessárias mais pesquisas sobre piroplasmose em Portugal, de forma a reduzir o número de casos positivos, reduzir os entraves à expansão do mercado do cavalo lusitano, educar a comunidade sobre os fatores de risco e alertar os veterinários sobre a epidemiologia da PE.

Equine Piroplasmosis (EP) results from infection by Babesia caballi and Theileria equi and is currently responsible for major economic losses at a worldwide level associated with commercial exchanges. When a horse is exported from Portugal to the USA, it must be accompanied by its identification, negative serological tests, health certifica te signed by the veterinarian. This disease is endemic in regions with tropical, subtropical and temperate climates. Most clinical signs derive from hemolytic anemia associated with fever. Diagnosis can be made by microscopic examination of blood smears, s erological tests, or by real time polymerase chain testing. Currently, the drug that is most effective in the treatment of these infections is imidiocarb dipropionate, however, there are other drugs available. This study aimed to obtain relevant informa tion on the incidence of piroplasmosis in Portugal through the analysis of serological tests carried out on 139 horses between 2020 and 2022, with the aim of observing the distribution of piroplasmosis in Lusitanian horses in the national territory evaluat ed for export. The present study found that despite the obligation to perform the ELISA serological test, the vast majority of positive cases were submitted to the IFAT serological test, namely 24.5%, with an increasing incidence of Theileria equi compared to Babesia caballi, 68%. and 20% respectively. Alto Alentejo being the area with the highest positivity among the nine regions, namely 68.2%. More research is needed on piroplasmosis in Portugal, in order to reduce the number of positive cases, reduce obs tacles to the expansion of the Lusitano horse market, educate the community about risk factors and alert veterinarians about the epidemiology of Piroplasmosis.
