Resumo: Infections by gastrointestinal parasites in domestic animals are very common worldwide, both in rural and urban areas. In addition to the pathogenic effects in the host, most of these parasites have a zoonotic nature, representing a potential risk to public health. Dog, being the animal which man has a closest relationship with, and as definitive host of various parasites, have an important role in the transmission of parasitic infections to people. Prevalence studies of gastrointestinal parasites are important not only in terms of overall prevalence, but also in terms of knowing the most common species in each geographical area. The concern of owners and veterinarians with the health and welfare of animals, as well with the zoonotic nature of these infections, have led to the implementation of regular deworming protocols. These protocols are often applied with wrong intervals, without first carried out coprology exams. There for, prevalence studies of gastrointestinal parasites facilitate the development of logical recommendations on the frequency of deworming and on the choice of drugs formulation to use, according to the parasites found in each region. This study aimed to estimate the prevalence of gastrointestinal parasites in owned dogs, and assess the need of deworming, determining the presence or absence of gastrointestinal parasites at the time of consult, by coprology exam. Samples were collected from dogs that underwent to prophylactic consults in two veterinary clinics in the district of Coimbra, Portugal. Individual questionnaires were completed for each animal, in order to gather dog’s characterization, management and deworming protocols information. Samples were processed through the Benchtop flotation procedure and McMaster modified technique for identification and counting of eggs and oocysts, respectively. A total of 77 fecal samples were taken. The overall prevalence of gastrointestinal parasites was 11.7% (n=9). The Ancylostomatidae family and the protozoon Cystoisospora spp. (C. canis and C. rivolta) were the most prevalent, with 33,3% each, followed by the helminthes species Dipylidium caninum (22,2%), Toxocara canis (22,2%) and Trichuris vulpis (11,1%). The prevalence was lower when compared to other studies in the country, which was expected, since the sampling came from household dogs, with restricted access to the street and dewormed regularly. These results show that we should combine regular deworming with coprology exams, in order to not over deworming, and direct the protocols to the most prevalent agents.

Para além dos efeitos patogénicos que apresentam para o hospedeiro, muitos destes parasitas têm um carácter zoonótico, representando um potencial risco para a saúde pública. O cão, sendo o animal com o qual o homem tem uma relação mais próxima, e como hospedeiro definitivo de várias espécies de parasitas, possui um papel importante na transmissão de infeções parasitárias às pessoas. Estudos de prevalência de parasitas gastrointestinais são importantes não só em termos de prevalências totais, mas também para se conhecerem quais as espécies mais comuns em cada área geográfica. A preocupação dos proprietários e médicos veterinários com a saúde e bem-estar dos animais, bem como com o carácter zoonótico que estas infeções apresentam, levaram à implementação de protocolos regulares de desparasitação. Muitas vezes estes protocolos são aplicados com intervalos errados, sem que antes sejam realizados exames coprológicos. Deste modo, estudos de prevalência de parasitas gastrointestinais facilitam o desenvolvimento de recomendações lógicas quanto à frequência de desparasitação dos animais e quanto à escolha dos princípios ativos a utilizar, de acordo com os parasitas encontrados em cada região. Este estudo teve como objetivos estimar a prevalência de parasitas gastrointestinais em cães de companhia e avaliar a necessidade de desparasitação, determinando a presença ou ausência de parasitas no momento da consulta, através de exames coprológicos. As amostras foram recolhidas a cães apresentados para consultas de profilaxia (vacinação/desparasitação), em duas clínicas veterinárias, no distrito de Coimbra, Portugal. Foram preenchidos questionários para cada animal, de modo a reunir informação sobre a caracterização do cão, o maneio e os protocolos de desparasitação. As amostras foram processadas semanalmente através do método de flutuação de Benchtop e da técnica de McMaster modificado, para identificação e contagem de ovos e oocistos, respetivamente. Um total de 77 amostras fecais foram recolhidas. A prevalência de parasitas gastrointestinais foi de 11,7% (n=9). A família Ancylostomatidae e o protozoário Cystoisospora spp. (C. canis e C. rivolta) foram os mais prevalentes, com 33,3% cada, seguidos pelos helmintas Dipylidium caninum (22,2%), Toxocara canis (22,2%) e Trichuris vulpis (11,1%). As prevalências foram inferiores em relação a outros estudos no país, o que era expectável, uma vez que a amostragem se tratou de animais de companhia, com acesso restrito à rua e desparasitados com frequência. Estes resultados mostram que devemos aliar a desparasitação regular com os exames coprológicos.Vieira, Maria João Nobre de Matos PereiraBarros, Luís Carlos MeirelesRepositório Comumda Silva, Carolina Claro Ferreira Paulino2016-12-14T10:38:50Z2016-06-21T00:00:00Z2016-06-21T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10400.26/16741201229536enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-09-05T13:56:48Zoai:comum.rcaap.pt:10400.26/16741Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T15:11:20.460461Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
