Deteção de anticorpos anti-Leishmania em roedores, lagomorfos e mustelídeos tidos como animais de companhia na Área Metropolitana de Lisboa

Abstract

A leishmaniose é uma doença parasitária de distribuição mundial provocada por um protozoário do género Leishmania, que em Portugal pertence à espécie Leishmania infantum. A infeção por L. infantum já foi detetada em diversas espécies de carnívoros domésticos e selvagens, lagomorfos, roedores, entre outros animais, incluindo o Homem. Entre as espécies de novos animais de companhia (NAC), sabe-se que os coelhos e furões são naturalmente infetados e suscetíveis à infeção por L. infantum. Contudo, pouco se sabe ainda acerca da infeção por Leishmania e leishmaniose em NAC. A presente dissertação teve como objetivos contribuir para uma melhor compreensão da infeção por L. infantum em NAC e sobre o seu potencial papel como reservatório na transmissão do protozoário a outros vertebrados, bem como para o estudo de outras possíveis hemoparasitoses que afetam estes animais de companhia, cada vez mais populares. Neste contexto, foi realizado um rastreio de infeção por L. infantum através da pesquisa de anticorpos pela técnica de imunofluorescência indireta (IFI) em 33 animais, entre os quais 24 coelhos, 6 porquinhos-da-Índia, 1 chinchila e 2 furões. Adicionalmente procedeu-se à pesquisa de outros parasitas através da observação de esfregaços sanguíneos de 26 destes animais, tendo alguns dos resultados sido confirmados por análises moleculares. Foi ainda realizado um questionário a todos os detentores dos animais incluídos no estudo. Através da técnica de IFI não foram detetados anticorpos anti-Leishmania infantum em nenhum dos animais testados e a observação dos esfregaços sanguíneos revelou-se negativa para outros parasitas. Embora os resultados tenham sido negativos, a presença de parasitas no organismo do animal não pode ser totalmente excluída. Através do inquérito realizado no âmbito deste estudo foi também evidente a falta de conhecimento dos detentores quanto à infeção por L. infantum e leishmaniose em NAC. O controlo da infeção por Leishmania/leishmaniose apoia-se no esclarecimento da comunidade científica e dos detentores dos animais. Neste sentido, os resultados obtidos neste estudo epidemiológico pioneiro realizado na região de Sintra, Portugal, permitiram um melhor conhecimento desta infeção em NAC na Área Metropolitana de Lisboa.

ABSTRACT - Anti-Leishmania antibody detection in rodents, lagomorphs and mustelids kept as pets in the Metropolitan Area of Lisbon - Leishmaniosis is a zoonotic infectious parasitic disease of worldwide distribution, caused by a protozoan of the genus Leishmania, which in Portugal is mainly caused by the L. infantum species. Leishmania infantum is known to infect domestic and wild carnivores as well as lagomorphs and rodents, amongst other animals, including humans. Exotic animals, such as rabbits and ferrets, are proven to be susceptible to L. infantum infection. However, currently there is not much information available on the Leishmania infection and leishmaniosis in exotic animals kept as pets. The present dissertation aimed to contribute to a better understanding of Leishmania infection in exotic pets and their role in the transmission of this parasites, as well as to detect hemoparasites in these increasingly popular pets. In this context, a survey of 33 asymptomatic exotic pets, including 24 rabbits, 6 guinea pigs, 1 chinchilla and 2 ferrets, was carried out to investigate the presence of L. infantum infection using the Indirect Fluorescent Antibody Technique (IFAT). Additionally, the blood smears of 26 of these animals were observed to search for other blood parasites and some of the results were confirmed through molecular analysis. All pet owners were also asked to answer a questionnaire. No anti-Leishmania infantum antibodies were detected using IFAT neither hemoparasites were observed in blood smears. Although the results were all negative, the presence of parasites cannot be completely excluded. The questionnaire revealed the general lack of awareness regarding L. infantum infection and leishmaniosis in exotic pets. Leishmania infection/leishmaniosis control is based on the enlightenment of the scientific community and animal owners. In this sense, in this pioneer survey, the obtained results promoted a better knowledge about L. infantum infection in exotic animals kept as pets at Sintra region, Metropolitan Area of Lisbon.
