“…A contaminação ambiental por dejetos de animais domésticos que perambulam em vias públicas é motivo de preocupação tanto para os ambientalistas como para profissionais sanitaristas. As fezes de cães e gatos podem albergar uma série de parasitas de importância em saúde pública, como formas infectantes de Toxocara canis ou T. cati, e de Ancylostoma braziliense e A. caninum (Matesco et al, 2006).…”

Larva migrans visceral e cutânea são zoonoses causadas por Toxocara spp. e Ancylostoma spp., respectivamente. O objetivo desta pesquisa foi avaliar a contaminação por estes agentes em áreas de lazer do município de Canoinhas, Santa Catarina, por meio das técnicas de sedimentação espontânea, centrífugo sedimentação e centrífugo flutuação. Das áreas de lazer examinadas (n=5), 100% apresentaram a areia contaminada e 80% apresentaram fezes contaminadas por Ancylostoma spp e/ou Toxocara spp. Destas, 100% apresentaram contaminação pelo Ancylostoma spp e apenas uma apresentou contaminação com ovos de Toxocara spp.. A presença de Ancylostoma spp. e de Toxocara spp. nas amostras de areia analisadas foi de 39%. Nos exames de fezes coletadas nas áreas de lazer foram detectadas 17% de amostras positivas, sendo detectado apenas ovos de Ancylostoma spp. O estudo revelou que a contaminação das áreas de lazer do município de Canoinhas é preocupante, reforçando a necessidade de implementar medidas efetivas para controle de zoonoses em áreas de lazer.

“…However, both pet species can harbor several parasites that are potentially transmissible to humans. Special attention should be given to ascarids and ancylostomatids, which affect dogs and cats worldwide, considering their spread and risk to animal and human health (MADRID et al, 2005;MATESCO et al, 2006;TRAVERSA, 2012;DANTAS-TORRES;OTRANTO, 2014).…”

“…Beach sand presents the epidemiological factors necessary for the occurrence of parasitic diseases transmitted by animals: weather conditions favorable to free-living stages of parasites and many stray dogs walking freely on the beach promenade and sand, resulting in waste accumulation MATESCO et al, 2006). Studies conducted in Brazil and other countries have found Ancylostoma spp., Toxocara spp., Giardia spp., and Trichuris spp.…”

Helminths and protozoa are examples of endoparasites that, during their biological cycles, can alternate between free-life stages and parasitic stages in the environment. Pets, such as dogs and cats, live together with humans and play a significant role in society; however, these animals may carry many parasites which, besides showing direct pathogenicity to the host, represent risks to human health, as is the case with parasitic zoonoses. Public areas like parks, gardens, squares, and beaches may offer risks to human users since these environments may contain feces deposited by parasitized dogs. This study verified the occurrence of helminth eggs and/or protozoan cysts or oocysts in fecal samples collected from sand strips at the beaches Armação do Pântano do Sul, Campeche and Morro das Pedras, in the south of Florianópolis Island, Santa Catarina State (SC), during the summer period. Pet feces were collected in the 2016-2017 summer season, from December 2016 to February 2017. In the Laboratory of Animal Parasitology (CCA/UFSC), fecal samples were processed based on Willis-Mollay flotation technique and Hoffman sedimentation technique. Samples from all three analyzed beaches were positive for the presence of parasites and fecal material was found along the seashore, sites where people freely walk barefoot. Of 104 fecal samples collected, 45 (43.27%) were positive for one or more parasites. The greatest prevalence was found in Campeche Beach, which had 72.22% positive samples. Ancylostomids were most prevalent, indicating that cutaneous larva migrans is likely to occur in humans. Other parasites such as Trichuris vulpis, Toxocara spp. and Giardia spp. were also detected in coproparasitological analyses. Based on the results, it was concluded that contamination of the beaches in Florianópolis Island, SC, constitutes a public health problem due to the possibility of zoonosis transmission. These results reinforce the importance of establishing health programs for parasite control and education programs to elucidate the risks of transmission of these zoonoses to the population, in an attempt to reduce environmental contamination risks at beaches of seaside resorts.

“…However, in recent years Sato et al (2005) and SoteroMartins et al (2013) have indicated the importance of assessing the sanitary quality of sand, especially to detect zoonotic parasites, to provide information for the formulation of new regulations or improvement of existing ones (the main one being Resolution 274/2000 from the National Environmental Council -CONAMA (CONAMA, 2000). Mentz et al (2004) and Matesco et al (2006) identified the presence of various parasite species, among them Strongyloides stercoralis, T. canis and A. brasiliensis, in sand samples, indicating the importance of beaches in the transmission of diseases to humans. Despite these studies, little is known about the epidemiological aspects of parasite contamination of sand in recreational areas and soil around houses in the state of Rio de Janeiro.…”

Intestinal helminths are among the pathogens most often found in humans and can result in serious pathological, such as visceral larva migrans syndrome. Domestic animals serve as the natural hosts, but under certain conditions humans can acquire infection, developing an atypical cycle. Thus, the contamination for animal droppings in public spaces, such as beaches, poses risk factor in the transmission, increasing the incidence of these zoonoses. In this context, informations about environmental health is necessary because the monitoring would be the first step for treating unhealthy environments. Therefore, the study monitored the sand of beaches of two islands within Guanabara Bay, Rio de Janeiro state, was carried out by traditional methods (Lutz and Baermann) and the ELISA immunological test, in order to determine the level and the influence of seasonality on this contamination. Among the genera detected, Ascaris sp. and Ancylostoma sp. occurred with greatest frequency, functioning as important biological markers of environmental contamination. The highest frequency of parasite structures occurred in the summer, meaning a greater risk of disease transmission. The results evidence the high level of environmental contamination and the seasonal variations of this contamination. Additionally, the data obtained from ELISA confirm the sensitivity of this technique to detect cysts and oocysts of protozoa in the sand samples analyzed. Keywords: environmental contamination, sand, parasitological techniques RESUMOHelmintos intestinais estão entre os patógenos mais frequentemente encontrados em seres humanos e podem resultar em patologias graves, como a síndrome de larva migrans visceral. Os animais domésticos servem como hospedeiros naturais e, em certas condições, os seres humanos podem ser afetados, desenvolvendo um ciclo atípico. Por isso, a contaminação por fezes de animais em espaços públicos, como praias, representa risco na transmissão, aumentando a incidência de possíveis zoonoses.
