- Contaminação ambiental e parasitária por fezes de canídeos na cidade de SantarémPublication . Crespo, Maria Virgínia; Fradinho, A. R.; Rosa, FernandaEm 2011, efetuou-se a colheita de 96 amostras de fezes de canídeos nas quatro freguesias urbanas, num total de 384. As amostras foram sujeitas a exames coprológicos. Em 53 amostras (13,80%) observaram-se ovos de helmintes e oocistos de protozoários com uma distribuição variável desde 7,29% (Marvila) a 28,13% (Sta. Iria). Identificaram-se ovos de Taeniidae e Dipylidiidae, Ancylostomatidae, Ascarididae, Trichuridae e Spiruridae e oocistos de Eimeriidae. Predominaram as infeções simples (73,58%), seguidas das duplas (22,64%). A prevalência global e o valor da eliminação por freguesia foram inferiores aos dados anteriormente obtidos. A gravidade das co-infeções aumentou ligeiramente, continuando-se a verificar o maior risco de infeção parasitária na freguesia de Sta. Iria e o menor em Marvila embora esta última tenha apresentado a maior contaminação ambiental por fezes. Estes resultados sugerem que as campanhas implementadas são insuficientes, ou não abrangem as áreas de maior risco, nomeadamente os bairros periféricos, pelo que, mais uma vez seria importante a tomada de medidas sanitárias e de sensibilização da comunidade residente nas áreas de risco identificadas.The main purpose of the present study was to determine the gastrointestinal parasitism present in faeces in Santarem, to compare it with previous studies, and to evaluate the efficiency of the sanitary measures implemented. In 2011, 96 dog faeces samples were taken in four parishes, with an overall of 384. Coprological exams were performed. In 53 faeces samples (13,80%) sheded helminth eggs and/or protozoa oocyst, which prevalence varied from 7,29% (Marvila) to 28,13% (Sta. Iria). Taeniidae and Dipylidiidae, Ancylostomatidae, Ascarididae, Trichuridae and Spiruridae eggs and Eimeriidae oocyst were observed. Simple infections prevail (73,58%) followed by double infections (22,64%). The overall prevalence and the parishes prevalence were lower than those obtained in earlier studies. Co-infections were slightly more severe, the major and the minor risk of parasitic infection was still registered in Sta Iria and Marvila, respectively, although the higher environmental contamination by dog faeces was observed in Marvila. These data suggest that the implemented measures are still inadequate or do not include the areas of major risk of parasitic infection, namely the suburban residential areas. Once again, these results pointed out to the importance of the implementation of prophylactic measures and community awareness activities in those identified risk areas.
- Intestinal parasites in dogs from the Center-west of PortugalPublication . Crespo, Maria Virgínia; Rosa, Fernanda; Morgado, Marina; Ferreirinha, Dario; Cerejo, A.; Madeira, MartaEnvironmental contamination by dog faeces in public areas is considered a risk factor to Public Health. Therefore, during a period of five years (2000-2005) a parasitological study on dog faeces was performed in Center-West region of Portugal. Coprological exams were performed. Out of 2806 samples analysed, 792 (28,23%) showed eggs/oocysts of intestinal parasites, with higher prevalences in rural areas (53,35%). Specimen eggs belonging to the families Taeniidae, Dipylidiidae, Ancylostomatidae, Ascarididae, Trichuridae and Spirocercidae and oocysts from Eimeriidae and Sarcocystidae, were identified. The results obtained pointed out to the continuity of prophylactic measures which has already been implemented in the studies areas.
