Rastreio parasitológico em lagomorfos, roedores e petauros do açúcar, através das técnicas de esfregaço fecal e Mini-FLOTAC

Abstract

ABSTRACT - Parasitological screening in lagomorphs, rodents and sugar gliders, through faecal smear and Mini-FLOTAC techniques - Nowadays, there is a great number of exotic animals kept as pets. These animals can be important reservoirs of parasites, some transmissible to humans. In this study, a parasitological screening was carried out on some small exotic mammal species kept as pets, in Portugal, to assess the prevalence of gastrointestinal parasites in these populations. Faecal samples were collected from 57 animals, including 23 rabbits, 14 guinea pigs, 2 chinchillas, 3 rats, 2 hamsters and 13 sugar gliders. Samples were analyzed through Mini-FLOTAC and faecal smear with Ziehl-Neelsen staining. Gastrointestinal parasites were identified in 8,77% (5/57) of the animals. Through Mini-FLOTAC it was possible to observe and quantify Eimeria spp. oocysts in 13,04% (3/23) of the rabbits. The faecal smear with Ziehl-Neelsen staining allowed the identification of Giardia spp. cysts in two out of three of the rat faecal samples. One common aspect between these 5 positive animals is the fact that no regular deworming is performed in a prophylactic way in none of them. Mini-FLOTAC is a relatively recent technique, very sensitive, precise and accurate, that in this study allowed the identification of one highly contagious species among rabbits. On the other hand, through faecal smear with Ziehl-Neelsen staining is possible to identify Cryptosporidium spp. oocysts and Giardia spp. cysts, two protozoans with zoonotic potential.

Atualmente existe um grande número de animais exóticos mantidos como animais de companhia. Estes animais podem ser importantes reservatórios de parasitas, alguns deles transmissíveis ao Homem. Neste estudo, foi realizado um rastreio parasitológico em algumas espécies de pequenos mamíferos exóticos de companhia, em Portugal, de forma a obter prevalências de parasitas gastrointestinais nessas populações. Foram obtidas amostras de fezes de 57 animais, incluindo 23 coelhos, 14 porquinhos da Índia, 2 chinchilas, 3 ratazanas, 2 hamsters e 13 petauros do açúcar. As amostras foram analisadas através do Mini-FLOTAC e do esfregaço fecal com coloração Ziehl-Neelsen. Foram identificados parasitas gastrointestinais em 8,77% (5/57) dos animais. Através do Mini-FLOTAC foi possível observar e quantificar oocistos de Eimeria spp. em 13,04% (3/23) dos coelhos. O esfregaço fecal com coloração Ziehl-Neelsen permitiu identificar quistos de Giardia spp. em duas das três amostras fecais das ratazanas. Um aspeto comum entre estes 5 animais positivos, é o facto de em nenhum deles ser realizada desparasitação regular de forma profilática. O Mini-FLOTAC é uma técnica relativamente recente, muito sensível, precisa e exata, que neste estudo permitiu a identificação de uma espécie altamente contagiosa entre coelhos. Por sua vez, através do esfregaço fecal com coloração Ziehl-Neelsen é possível identificar oocistos de Cryptosporidium spp. e quistos de Giardia spp., dois protozoários com potencial zoonótico
