Resumo
A proximidade do Homem com seus animais de companhia traz benefícios físicos e psicológicos, porém, deve-se ter em atenção as doenças parasitárias, principalmente aquelas que, devido ao seu potencial zoonótico, possam pôr em risco a saúde das pessoas.
Com o objetivo de avaliar a presença de parasitas e potenciais zoonoses parasitárias em áreas frequentadas por cães, foram colhidas amostras de solo e de fezes em parques caninos, jardins públicos e praias dos concelhos de Sintra e Cascais.
Foi realizado um inquérito por meio de questionários presenciais a 111 tutores para se obter a opinião destes sobre parasitoses nos seus cães e o seu conhecimento sobre o potencial zoonótico. Foram analisadas 86 amostras de fezes e 30 amostras de solo de 10 locais públicos frequentados por tutores com os cães.
Nas amostras de fezes observou-se que 36% encontravam-se contaminadas por ovos ou larvas de parasitas. Observou-se a presença de larvas ou ovos de ancilostomídeos em 20,39% e ovos de Toxocara spp. em 15,12% das amostras de fezes. Das amostras de solo, 50% estavam contaminadas por ovos ou larvas de parasitas, comprovando o risco zoonótico nos concelhos de Sintra e Cascais.
De acordo com os dados obtidos pelos questionários, 55,8% dos tutores não tinham conhecimento sobre zoonoses nem sobre contaminação ambiental por fezes e o seu potencial risco zoonótico. Do total de inquiridos, 85,5% afirmaram recolher as fezes dos seus cães, 42,3% concordavam que é preciso aumentar as campanhas de conscientização e 55,8% consideram benéfico realizar campanhas nas escolas para a conscientização da importância da recolha das fezes nas vias públicas.
Como conclusão deste estudo, pode-se observar que as desparasitações não estão a ser suficientes para evitar a contaminação ambiental e o risco zoonótico. Neste estudo também se observou que a maioria dos tutores entrevistados não têm conhecimento sobre o que são zoonoses, o que revela a falta de informação sobre o assunto.
The proximity of human beings and their companion animals is correlated with physical and psychological benefits. However, attention must be drawn to parasitic diseases, with emphasis to those that present zoonotic potential and pose an increased risk to humans. This study aimed to evaluate the presence of parasites and parasitic zoonoses in soil and feces collected in dog parks, public gardens and beaches in the Municipalities of Sintra and Cascais, as well as to obtain dog owners’ opinions on the subject and assess their knowledge of zoonotic potential through questionnaires. A total of 86 faecal samples and 30 pooled soil samples were collected from 10 pre-selected public locations frequented by owners with the dogs. Simultaneously, 111 questionnaires were answered by dog owners in the same locations. The results from feces and. We detected parasitic eggs or larvae in 36% of the fecal samples. Hookworm larvae or eggs were present in 20.93% and Toxocara spp. Soil analyses showed an overall presence of parasitic eggs and larvae in 50% of the soil samples, confirming the zoonotic risk in the Municipalities of Sintra and Cascais The analysis of the data obtained through the questionnaires showed that 55.8% of dog owners lacked knowledge about zoonoses and environmental contamination from feces. A total of 85.5% of dog owners declared collecting the feces of their dogs, 42.3% agreed that it is necessary to increase awareness, and 55.8% agreed that increasing education campaigns in schools to change people’s attitude towards collecting their dog's feces in public places would be beneficial. This study showed that the current levels of deworming are not enough to avoid environmental contamination and zoonotic risk. It also shows that most of the dog owners interviewed is not aware of what zoonoses are, which reveals an overall lack of information about of the subject.
